Downloading DjVu files from Internet Archive ( #

Clicking DjVu book links on opens them in a Java applet within the web browser, with no option to save. Right clicking and "saving link as..." results in a tiny HTML file being downloaded instead. Here's how to download the actual DjVu file (we'll use H.G. Wells' The wonderful visit in this example):
  1. Right click and copy the DjVu link:
  2. Paste the link into your browser's address bar
  3. Add an extra forward slash before "stream":
  4. Press Enter to begin downloading the DjVu file
UPDATE: The DjVu file can also be downloaded from the directory listing: simply click the "HTTP" link to the right of "All Files:" to access.

Ensign, Demint to force vote on health care bill unconstitutionality #

WASHINGTON, D.C. - Today, U.S. Senators Jim DeMint (R-South Carolina) and John Ensign (R-Nevada), raised a Constitutional Point of Order on the Senate floor against the Democrat health care takeover bill on behalf of the Steering Committee, a caucus of conservative senators. The Senate will vote tomorrow on the bill's constitutionality.

"I am incredibly concerned that the Democrats' proposed individual mandate provision takes away too much freedom and choice from Americans across the country," said Senator Ensign. "As an American, I felt the obligation to stand up for the individual freedom of every citizen to make their own decision on this issue. I don't believe Congress has the legal authority to force this mandate on its citizens."

"Forcing every American to purchase a product is absolutely inconsistent with our Constitution and the freedoms our Founding Fathers hoped to protect," said Senator DeMint. "This is not at all like car insurance, you can choose not to drive but Americans will have no choice whether to buy government-approved insurance. This is nothing more than a bailout and takeover of insurance companies. We're forcing Americans to buy insurance under penalty of law and then Washington bureaucrats will then dictate what these companies can sell to Americans. This is not liberty, it is tyranny of good intentions by elites in Washington who think they can plan our lives better than we can."

Americans who fail to buy health insurance, according to the Democrats' bill, would be subject to financial penalties. The senators believe the bill is unconstitutional because the insurance mandate is not authorized by any of the limited enumerated powers granted to the federal government. The individual mandate also likely violates the "takings" clause of the 5th Amendment.

The Democrats' healthcare reform bill requires Americans to buy health insurance "whether or not they ever visit a doctor, get a prescription or have an operation." If an American chooses not to buy health insurance coverage, they will face rapidly increasing taxes that will rise to $750 or 2% of their taxable income, whichever is greater.

The Congressional Budget Office once stated "A mandate requiring all individuals to purchase health insurance would be an unprecedented form of federal action. The government has never required people to buy any good or service as a condition of lawful residence in the United States."

A legal study by scholars at the nonpartisan Heritage Foundation concluded: "An individual mandate to enter into a contract with or buy a particular product from a private party, with tax penalties to enforce it, is unprecedented-- not just in scope but in kind--and unconstitutional as a matter of first principles and under any reasonable reading of judicial precedents."

Xcopy Windows to a new hard drive #

While imaging a 160GB drive with four partitions (Dell Diag, Recovery, OS, MediaDirect) to a new 500GB drive via an Acronis True Image boot CD, something went terribly wrong. Long story short, neither drive would boot (stuck in perpetual reboot loop) though files were visible on both drives. After wrangling with partition and recovery tools on the 500GB drive to no avail, the following process worked:
  1. Wiped all partitions on the 500GB drive and created a single NTFS partition
  2. Installed Vista normally on 500GB drive
  3. Booted from Microsoft Diagnostics and Recovery Toolset (DaRT) CD
  4. Erased all files from C: on 500GB drive
  5. Copied all files from 160GB drive's OS partition (F:) to 500GB drive (C:) via xcopy:
    xcopy f:\*.* c:\ /b /c /e /h /k /o /r /x /y
  6. Booted from 500GB drive - still no joy: "Missing operating system"
  7. Booted from Vista install disc and selected "Repair your computer" (with the vague idea of trying fixboot and perhaps fixmbr)
  8. The following message appeared: "Windows found problems with your computer's startup options. Do you want to apply repairs and restart your computer?"
  9. Clicked "Repair and restart" and booted from 500GB drive
  10. Windows Vista started normally, with all data and apps intact!

UPDATE: Robocopy replacement (covers another interesting tool, strarc.exe)

Bundled Snow Leopard Upgrade DVDs do *not* work on older Macs with blank drives #

There are many assertions around the web that the Mac OS X Snow Leopard Upgrade DVD works exactly like the full version. Here's an example of such a claim from Macworld:
However, the Snow Leopard upgrade DVD does not require that you have Leopard installed; it's a full install disc that works on any Intel Mac.
and another from MacInTouch:
Can I install the Snow Leopard upgrade on a blank hard disk?
Yes. According to a number of reports, you can even install it on a Mac that does not have a Leopard disk attached.
While this may be true of the retail upgrade disc, bundled DVDs and those issued under the Mac OS X Snow Leopard Up-to-Date Program (distinguishable by the notice "This software is part of a hardware bundle - not to be sold separately") do not work on older Macs with blank drives, as this screenshot demonstrates:
Mac OS X can't be installed on this computer. This disc requires that Mac OS X 10.5 or later already be installed on your computer.
For bots, screen readers, and image-free browsers, here it is in plain text:
Mac OS X can't be installed on this computer. This disc requires that Mac OS X 10.5 or later already be installed on your computer. If you want to restore your system from a Time Machine backup, click "Restore from Backup".
The only choices are "Restore from Backup" and "Restart". Not even the usual utilities (Terminal, Disk Utility, etc) are available. This message can be avoided by plugging in an external drive with Leopard installed (including another Mac in Target Disk Mode) or by remastering the DVD with a few minor changes.

Batch replace text in PDF files #

Simple text replacements in simple PDF documents can be made with, part of CAM-PDF-1.52, which, by the way, includes many other cool tools like:
$ perl -MCPAN -e shell
If this is the first time you've run CPAN, it will ask you a series of questions - the default answers worked fine for me. When the cpan> prompt appears, install the CAM::PDF module:
cpan> install CAM::PDF
Now let's see if our PDF allows modification:
$ pcasm-book.pdf 
File:         pcasm-book.pdf
File Size:    1071411 bytes
Pages:        195
Author:       Paul A. Carter
CreationDate: D:20050320210800
Creator:      LaTeX with hyperref package
Keywords:     80x86 assembly programming
Producer:     pdfTeX-1.10b
Subject:      80x86 Assembly Language Programming
Title:        PC Assembly Language

PDF version:  1.4
  Passwd:     none
  Print:      yes
  Modify:     yes
  Copy:       yes
  Add:        yes
As it does, let's batch replace the word "Borland" with the word "Inprise" and name the new file output.pdf:
$ -o pcasm-book.pdf Borland Inprise output.pdf
That seems to have worked, but there are still instances of "Borland" in the file - why were they not changed? The following script by Adam314 will output the entire file, including the hidden PDF formatting codes:
use warnings;
use strict;
use CAM::PDF;
my $infile = '/path/pcasm-book.pdf';

#open file
my $doc = CAM::PDF->new($infile) || die "$CAM::PDF::errstr\n";
#look for string
for my $page (1..$doc->numPages) {
	my $content = $doc->getPageContent($page);
		print $content
Sure enough, the string "Borland" only shows up twice. Where are all the others? Why, surrounded by hideous formatting code like these examples:
In his link above, Adam314 offers advice for replacing instances like these with regex. At this point I grew rather weary, however, especially as text replacements were wont to cut off or run into other words. However, for simple text replacements in simple PDF documents, may come in handy.

This tip is particularly useful when copying folders like My Documents, My Pictures, etc from Windows machines to OS X. Rather surprisingly, these folders are actually assigned the Read-only attribute in Windows:
Unlike the Read-only attribute for a file, the Read-only attribute for a folder is typically ignored by Windows, Windows components and accessories, and other programs. For example, you can delete, rename, and change a folder with the Read-only attribute by using Windows Explorer. The Read-only and System attributes is only used by Windows Explorer to determine whether the folder is a special folder, such as a system folder that has its view customized by Windows (for example, My Documents, Favorites, Fonts, Downloaded Program Files), or a folder that you customized by using the Customize tab of the folder's Properties dialog box.

OS X honors the Read-only attribute by dutifully locking the directories, leading to unexpected and generally undesirable results.

UPDATE: OS X also hides (in the Finder) files and folders that were hidden in Windows (Local Settings, AppData, etc). chflags can be used to unhide these as well:

$ chflags -R nohidden directory
$ chflags -R hidden directory

Plutarch's "On the Eating of Flesh" #

Can you really ask what reason Pythagoras had for abstaining from flesh? For my part I rather wonder both by what accident and in what state of soul or mind the first man did so, touched his mouth to gore and brought his lips to the flesh of a dead creature, he who set forth tables of dead, stale bodies and ventured to call food and nourishment the parts that had a little before bellowed and cried, moved and lived. How could his eyes endure the slaughter when throats were slit and hides flayed and limbs torn from limb? How could his nose endure the stench? How was it that the pollution did not turn away his taste, which made contact with the sores of others and sucked juices and serums from mortal wounds? ...

It is certainly not lions and wolves that we eat out of self-defense; on the contrary, we ignore these and slaughter harmless, tame creatures without stings or teeth to harm us, creatures that, I swear, Nature appears to have produced for the sake of their beauty and grace. But nothing abashed us, not the flower-like like tinting of the flesh, not the persuasiveness of the harmonious voice, not the cleanliness of their habits or the unusual intelligence that may be found in the poor wretches. No, for the sake of a little flesh we deprive them of sun, of light, of the duration of life to which they are entitled by birth and being.
The entire chapter can be found in Volume 12 of Plutarch's Moralia. For those who would like to enjoy on their Kindle, Treo, text-to-speech device, etc, I have put together a plain text version here. Bill Thayer has posted HTML versions of Gryllusa and De sollertia animalium from the same volume.

Resume an interrupted file copy #

For those times when you've copied 200 of 210GB and then: the network connection goes down, someone inadvertently unplugs your USB drive, or Totus Copy crashes (as I just experienced), rsync can save you from having to start over from square one:

$ rsync --ignore-errors --archive --recursive --compress --partial --progress --ignore-existing --append /source/ /target/

Leopard and Snow Leopard still come packaged with the woefully out of date rsync 2.6.9, which does not preserve metadata or modification times correctly, even when using the -E and -t options. Mike Bombich explains how to download, compile, and install rsync 3.0.6, which does not suffer from these issues.

UPDATE: Added the ill-explained "--ignore-errors" option above. While the man page says its purpose is to "delete even if there are I/O errors", Mark Carroll points out that it would be more accurate to say something like "Go ahead even when there are IO errors, instead of regarding them as being fatal".

Convert between Mac, Unix, and DOS/Windows EOL characters (CR, LF, CRLF) #

Craig Stuart Sapp's flip converts ASCII files between between Mac (OS 9 and earlier), *nix (including OS X), and DOS/Windows newline formats. As the provided OS X binary was compiled in 10.3 for PowerPC, I've compiled a much smaller Intel binary in 10.5.  📺

flip's source code also explains a method for converting line endings via Perl:
Mac to Unix:
   perl -i -pe 's/\015/\012/g' mac-file
Mac to DOS:
   perl -i -pe 's/\015/\015\012/g' mac-file
Unix to Mac:
   perl -i -pe 's/\012/\015/g' unix-file
Unix to DOS:
   perl -i -pe 's/\012/\015\012/g' unix-file
DOS to Unix:
   perl -i -pe 's/\015\012/\012/g' dos-file
DOS to Mac:
   perl -i -pe 's/\015\012/\012/g' dos-file
Here are a few more possibilities from Jacek Artymiak's Filtering files with tr:
Mac -> UNIX: tr '\r' '\n' < macfile > unixfile
UNIX -> Mac: tr '\n' '\r' < unixfile > macfile
DOS -> UNIX: tr -d '\r' < dosfile > unixfile
UNIX -> DOS: '{ print $0"\r" }' < unixfile > dosfile

The first and last word on attire from Douglas Sutherland's The English Gentleman:
  The knack gentlemen have of dressing badly and getting away with it is best illustrated by the story of the gentleman who was accosted by a friend walking along Piccadilly in clothes which were well below the best sartorial standards.

  'It does not matter how I dress in London,' he claimed. 'Nobody here knows me.'

  Later the same friend visited him in the country where his clothes were no better.

  'It does not matter how I dress here', he said, 'Everybody knows me.'

Remote Desktop crashes host when connecting from client #

A brand new Dell Precision T3500 running Windows XP SP3 was crashing hard every time a client connected via Remote Desktop. Sometimes the host monitor would freeze with funky graphic patterns, so the display adapter (NVIDIA Quadro NVS 295) was suspected.

The fix turned out to be adding a new DWORD named SessionImageSize with a value of 20 to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] on the host machine.

Apparently this issue can also manifest as being unable to connect to Remote Desktop at all, with the following error message: "This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator."

dd block size #

Yesterday's post got me researching block sizes in dd. The clearest explanation was in Brian Carrier's File System Forensic Analysis on page 61:
"The default block size is 512 bytes, but we can specify anything we want using the bs= flag. We can copy 1 byte at a time, or we can copy 1GB at a time. Any value will work, but some values will give you better performance than others. Most disks read a minimum of 512 bytes at a time and can easily read more at the same time. Using a value that is too small is wasteful because the disk will need to be frequently read, and time will be wasted in the copying process. If you choose a value that is too large, you will waste time filling up the buffer in dd before the copy is performed. I have found that values in the 2KB to 8KB range work well."

Securely wiping floppy disks under OS X in Terminal #

Faced with several dozen floppy disks that needed wiping, Disk was looking a bit cumbersome: Disk Utility > click floppy drive > Erase > Security Options... > Zero Out Data > OK > Erase... > Erase

I decided to give sudo dd if=/dev/zero of=/dev/fd0 a go:
dd: /dev/fd0: Operation not supported.

Ah! Perhaps OS X does not use fd0:
$ ls /dev/fd0
ls: /dev/fd0: No such file or directory

In that case, let's have a look at what we've got:

$ diskutil list
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:      GUID_partition_scheme                        *111.8 Gi   disk0
  1:                        EFI                         200.0 Mi   disk0s1
  2:                  Apple_HFS MacBook HD              111.5 Gi   disk0s2
  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:                            TEST                   *1.4 Mi     disk1

OK, how about:

$ sudo dd if=/dev/zero of=/dev/disk1
dd: /dev/disk1: Resource busy
What if we unmount the floppy from the Finder and then try the same command?
$ sudo dd if=/dev/zero of=/dev/disk1
dd: /dev/disk1: Operation not supported

A quick search turned up the answer - unmount from within diskutil, not the Finder:

$ diskutil unmount /dev/disk1
Volume TEST on disk1 unmounted
$ sudo dd if=/dev/zero of=/dev/disk1
dd: /dev/disk1: end of device
2881+0 records in
2880+0 records out
1474560 bytes transferred in 110.617912 secs (13330 bytes/sec)

That worked beautifully, if slowly: it took almost two minutes to wipe a single floppy disk (fiddling with the block size seemed to help, but I was not inclined to spend much time investigating further see update below). Macworld and the diskutil manpage turned up a much faster method that had the additional benefit of not requiring root privileges:

$ diskutil secureErase 0 /dev/disk1
Started erase on disk1 TEST
Finished erase on disk1 TEST

This single-pass zero-fill erase took less than 30 seconds to complete. Wiping the floppies was now a breeze:

$ diskutil unmount /dev/disk1 && diskutil secureErase 0 /dev/disk1

UPDATE 1: Rather than using /dev/disk1 (which is the block device, AKA buffered device or cooked device) I should've been using /dev/rdisk1 (the raw device). This made the dd process slightly faster than even diskutil when using block sizes of 1440k and 360k. Connected raw devices can be listed by issuing the ls /dev/rdisk? command. See Block device versus raw device performance for more information.

UPDATE 2: diskutil zerodisk disk# (replacing "#" with the disk's number) will automatically unmount the floppy then zero it out.

For those who doubt the efficacy of zeroing a disk, see:

Wipe MBR / Track 0 #

When particularly nasty malware infections call for formatting a drive, I always like to start by wiping track 0. This will delete not only the MBR and any boot sector viruses, but anything else in the first 63 sectors of the hard disk, including boot overlays (like EZ-BIOS), boot managers (like BootIt NG), harebrained DRM schemes (like some versions of TurboTax), etc, so caution is advised. This process won't help solve persistent BIOS infections like this one: New BIOS Virus Withstands HDD Wipes. The commands below WILL permanently delete data - use at your own risk (and joy).

To wipe just the MBR:
dd if=/dev/zero of=/dev/foo bs=512 count=1

To wipe all of track zero:
dd if=/dev/zero of=/dev/foo bs=512 count=63

"Zero out" the entire drive:
dd if=/dev/zero of=/dev/foo

You'll need to replace foo with the appropriate device (hda, sda, etc). List partitions and disks via one of these methods:

Vincent Stahl kindly wrote in to share his open source Swiss File Knife File Tree Processor:
"This tool is a collection of tiny applications itself: grep, tree size list, instant ftp server, text line filter, text replace, duplicate file finder, split/join files, create md5 lists, run command on many files, extract strings, and more- all in one executable still matching your size limit (below 1.4 MB). It has no installer, no dependencies, needs no DLL's - nothing, just type 'sfk' to get the overview of all available subcommands."
Besides Windows, binaries are available for Ubuntu, DSL, and OS X. Here are just a few of the many possible uses:

sfk list -late -hiddenList latest (i.e., most recent) 50 files in current directory and subdirectories, including system and hidden files
sfk stat . -bytesDisplay current directory tree size statistics in bytes
sfk find -text . epictetusSearch text files in current directory and subdirectories for "epictetus" (case insensitive)
sfk ftpserv -port=21 -rwSimple FTP server, providing read/write access to current directory
sfk ftp get fooConnect via FTP to port 21 of and get foo
sfk httpserv -port=80Instant HTTP server, providing access to current directory
sfk deblank . -yesReplace blanks in filenames within current directory and subdirectories with underscore (run without "-yes" to simulate)
sfk md5 foo.txtGenerate MD5 hash of foo.txt
sfk dupfind .Find duplicate files in current directory and subdirectories

Compress, encrypt, and copy data to offsite server #

Under Windows, I was using AxCrypt and WinSCP from the context menu to compress, encrypt, and send data to an offsite server. Under OS X, I am now using a simple bash command list to achieve the same thing faster and with greater compression:

$ /Applications/file/ a -mx9 -pSECRET -mhe ~/Desktop/file.7z ~/Documents/file.ext && scp -P 2012 ~/Desktop/file.7z && rm ~/Desktop/file.7z

Let's break down what's happening here:
  1. /Applications/file/ Call the 7-Zip file archiver contained in BetterZip (which I happened to have from a MacUpdate Promo Bundle). There are several other Mac binaries available or you can download and compile from source.
  2. a Add file(s) to archive
  3. -mx9 Maximum ("Ultra") compression
  4. -pSECRET Set password to SECRET
  5. -mhe Encrypt archive headers (i.e., filenames will be encrypted also)
  6. ~/Desktop/file.7z Name of archive to create or add files to
  7. ~/Documents/file.ext File to compress and encrypt
  1. && Execute next command only if previous command returns an exit status of zero (i.e., wait for command to complete successfully before proceeding)
The next section assumes public-key authentication has been configured (see part 2 of Hardening SSH and Mounting Remote Filesystem in OS X Finder via SSHFS for more information):
  1. scp Secure copy command
  2. -P 2012 Connect via port 2012
  3. ~/Desktop/file.7z Local file to copy
  4. Remote username and domain followed by directory where file will be copied to
These next two steps are optional:
  1. && Execute next command only if previous command returns an exit status of zero (i.e., wait for command to complete successfully before proceeding)
  1. rm ~/Desktop/file.7z Delete 7z archive from local computer

Unpack / extract Dell driver EXE files under OS X #

The Windows XP SP3 install CD lacks many SATA drivers, resulting in a BSOD shortly after booting the disc on unsupported hardware. One solution is to copy the required SATA driver to a floppy and press F6 during boot to load. Dell drivers come packed in EXE files - OS X users can extract them via: unzip:
$ unzip -L ~/temp/R173412.exe 
Archive:  /Users/user/temp/R165147.EXE
  inflating: iastor.sys              
  inflating: txtsetup.oem            
  inflating: iaahci.inf              
  inflating: iastor.inf              
  inflating: version.txt             
GUI lovers note: OS X's "Archive" was unable to extract the files, but FileJuicer ($18 shareware with 6 day trial) matched unzip's performance. (Postscript: SATA config had to be changed from AHCI to ATA in Optiplex 330 BIOS to prevent BSOD when loading driver from floppy.)

Rename photos based on thumbnail order #

How to arrange a group of thumbnails and rename them sequentially based on their position:
  1. Navigate to folder containing photos in Windows Explorer
  2. View > Thumbnails
  3. Click and drag thumbnails into desired order. It may be advisable to enable View > Arrange Icons by > Align to Grid.
  4. Edit > Select All
  5. Right click on first photo and rename to desired_name (1). That is, the desired file name, followed by a space, followed by an open parentheses, followed by the number one, followed by a close parentheses.
  6. All photos will be renamed to desired_name (#), where # corresponds to the photo's position in the thumbnail layout.
At this point, our filenames look something like: name (1), name (2), name (3)... (if Windows Explorer does not list files in proper numerical order (e.g., "10" follows "1" instead of "9"), you can correct this with TweakUI: Explorer > check "Use intuitive filename sorting"). To get rid of the parentheses and renumber the files with leading zeroes:
  1. Launch ReNamer
  2. Settings > General > check "Use natural order sorting algorithm..." > Save (you may need to restart the program for this to take effect)
  3. Add Folder
  4. Add rule > Serialize > check "Incremental" > check "Pad with zeroes to reach length" > insert 3 for the number of zeroes > click "Add Rule"
  5. Add rule > CleanUp > check "(...)" to the right of "Strip out content of brackets:" > click "Add Rule"
  6. Review results before committing changes. The new filenames should look something like: 001name, 002name, 003name ...
Two other possible (though untested) methods using commercial software: with IMatch and Photoshop Elements.

RAID not supported by EASEUS Partition Master Server Edition Boot CD #

There are a number of Partition Magic clones which offer bootable CDs. I needed one that would support a SCSI RAID 1 array, and thought I had found the solution in EASEUS Partition Master Server Edition: "EASEUS Partition Master allows you to resize partition during the copy process with hardware RAID supported. And it can boot from both CD/DVD and Windows System."1.

UPDATE: EASUS has kindly updated their webpage to reflect the fact that RAID is not supported by the boot CD. I am very impressed with their quick response, and after using the installed version, am equally impressed with their product.

After purchasing the software (the boot disc cannot be created from the trial download), I burned and booted from the CD. Imagine my surprise when greeted by this message:

EASEUS Partition Master Server Edition Boot CD message

Not only does it not support RAID, it doesn't support Vista, Windows 2008, or creating/deleting partitions which occur before virtually any Windows partition. This was not mentioned in their documentation anywhere (though I later found a single forum post which mentioned the lack of RAID support). I emailed back and forth with their tech department who were very kind, but could not offer a solution. I once again set out to find a bootable partition manager that would support RAID. Here are a few possibilities: If you have any suggestions for a bootable partition manager that supports RAID, please be so kind as to send them in.

Formatting partitions over 32GB as FAT32 in Windows XP #

Searching for a quick way to format a partition over 32GB as FAT32 in Windows XP, I tried this solution recommended in a number of places:
C:\>format drive_letter /fs:fat32
Here's what I got:
The type of the file system is RAW.
The new file system is FAT32.

Proceed with Format (Y/N)? y
Verifying 40960M
Eons pass, stars are born and burn out, entire universes spring into existence, spiral outward, and return to the formless void... and then, finally:
The volume is too big for FAT32.
Older and wiser, I decided to give the tiny, open source fat32format a go:
C:\>fat32format d:
Warning ALL data on drive 'd' will be lost irretrievably, are you sure (y/n) :y
Approximately one second later, the format was complete. Incredulous, I chkdsk'd the drive - it was formatted perfectly. fat32format's documentation seems to bear this out ("It should take about 4 seconds per Terabyte to format the disk." - wow!). May this lesson save humanity from many wasted hours.

Best lightweight antivirus #

DefenseWall is actually a HIPS (Host Intrusion Prevention System), not antivirus. In my testing, it is much more effective at preventing malware infections than definition-based antivirus applications. also offers a strong recommendation (albeit with annoying affiliate downloads instead of a link to the homepage). The developer of DefenseWall, Ilya Rabinovich, responded to inquiries rapidly, and generously offered a discount for a family in need. The app particularly shines on older hardware which traditional antivirus products (and even the "light" Panda Cloud Antivirus) slow to a crawl. After hours perfecting the ideal install for a worthy cause, it's nice to know that DefenseWall (along with user education) will keep it safe and clean.

Postscript: Two similar freeware applications, DriveSentry 3.3 and GeSWall 2.9 did not work out; the former due to its bloated size (over 50MB download compared to around 3MB for DefenseWall) and the latter since it does not work on FAT32-formatted drives.

Malware causes "Access is denied" error #

A malware infection disabled explorer.exe and all antimalware apps as soon as they were launched (in both Normal and Safe modes) by changing permissions on the EXEs. After clearing the infection with DaRT/Standalone System Cleaner, permissions had to be fixed on the apps. As Windows XP Home does not include the Security tab in Normal Mode by default (Claus breaks down a number of workarounds), the CACLS command came in handy. Files which would not launch had been modified as in this example:
C:\Program Files\Prevx>cacls prevx.exe
C:\Program Files\Prevx\prevx.exe Everyone:(NP)(special access:)
These permissions are easily replaced:
C:\Program Files\Prevx>cacls prevx.exe /g administrator:f
Are you sure (Y/N)?y 
processed file: C:\Program Files\Prevx\prevx.exe
Now Administrator has full access:
C:\Program Files\Prevx>cacls prevx.exe
C:\Program Files\Prevx\prevx.exe ComputerName\Administrator:F
and the program runs normally. Compare and match permissions from a clean system for best results.

It's better to green your diet than your car #

"Thinking of helping the planet by buying an eco-friendly car? You could do more by going vegan, say Gidon Eshel and Pamela Martin of the University of Chicago... The typical US diet, about 28 per cent of which comes from animal sources, generates the equivalent of nearly 1.5 tonnes more carbon dioxide per person per year than a vegan diet with the same number of calories, say the researchers... By comparison, the difference in annual emissions between driving a typical saloon car and a hybrid car, which runs off a rechargeable battery and gasoline, is just over 1 tonne. If you don't want to go vegan, choosing less-processed animal products and poultry instead of red meat can help reduce the greenhouse load."

Editing ISO images #

Converting a retail Windows XP ISO image to an OEM version was made even simpler thanks to ISO Master (free for Linux, $20 for Windows). These steps were performed in Ubuntu 9.04:
  1. Download and install ISO Master via Synaptic Package Manager (search for "isomaster" without the quotes.)
  2. Launch ISO Master from Sound & Video in the Main Menu.
  3. Tools > Options > replace "mousepad" with "gedit" (again, without quotes)
  4. File > Open > select desired ISO image (in this example, we'll use the Windows XP ISO mentioned above)
  5. Let's edit SETUPP.INI: In the bottom pane, double click the I386 folder, right click SETUPP.INI, and click Edit
  6. gedit will open SETUPP.INI. Make desired changes.
  7. In gedit, click File > Save > and then close gedit
  8. In ISO Master, click File > Save As > type a new filename (it will not allow you to overwrite the original ISO image) and click Save.

UPDATE: Had trouble adding a file to an existing ISO image with ISO Master, but UltraISO did the trick.

Convert retail Windows XP to OEM #

Unlocking WinXP's setupp.ini explains how to force Windows XP to accept retail, OEM, or volume license keys during installation (as well as how to change the CD's behavior). This is especially useful for installing Windows XP on a computer with an OEM license when you've only got a retail CD handy. Working from a retail ISO image, simply open I386\SETUPP.INI in a text editor and replace the last 3 digits of the Pid with "OEM" (sans quotes). Tested successfully with HP, Gateway, and Toshiba OEM product keys. See also: Editing ISO images and Product IDs (cached copy).

We may be the sons of whomsoever we will #

Seneca reminds us of our true endowment:
We are wont to say that it was not in our power to choose the parents who fell to our lot, that they have been given to men by chance; yet we may be the sons of whomsoever we will. Households there are of noblest intellects; choose the one into which you wish to be adopted; you will inherit not merely their name, but even their property, which there will be no need to guard in a mean or niggardly spirit; the more persons you share it with, the greater it will become. These will open to you the path to immortality, and will raise you to a height from which no one is cast down. This is the only way of prolonging mortality -nay, of turning it into immortality. Honours, monuments, all that ambition has commanded by decrees or reared in works of stone, quickly sink to ruin; there is nothing that the lapse of time does not tear down and remove. But the works which philosophy has consecrated cannot be harmed; no age will destroy them, no age reduce them; the following and each succeeding age will but increase the reverence for them, since envy works upon what is close at hand, and things that are far off we are more free to admire. The life of the philosopher, therefore, has wide range, and he is not confined by the same bounds that shut others in. He alone is freed from the limitations of the human race; all ages serve him as if a god. Has some time passed by? This he embraces by recollection. Is time present? This he uses. Is it still to come? This he anticipates. He makes his life long by combining all times into one.

Dell Inspiron 600m - Disable flashing orange LED (dead battery indicator) #

The Dell Inspiron 600m has a row of display lights just under the LCD panel. From left to right they are: power, hard drive activity, battery, and Bluetooth. When the battery no longer holds a charge, its LED blinks orange four times and then green once. Removing the battery altogether stops the blinking, but then the laptop wobbles as one of its four feet is on the battery. I was able to "disable" the orange flashing by removing the center control cover and covering the tiny LED on the motherboard with electrical tape. Of course, if your battery light is flashing, you should contact Dell immediately since it might explode anytime.

OS X: Move data from an old user account to a new one on the same computer #

Migrating data from an old user account to a new one under OS X (without first copying it to another device) can be a little tricky due to permissions issues. This procedure worked well for us, but it might not for you; proceed at your own risk (and joy):

  1. BACKUP all critical data to an external drive and then disconnect that drive. Do not reconnect until you are SURE that everything has worked out.
  2. Create the new user account and log in at least once. Do not create any new data under this account, as it would simply be overwritten in the ensuing steps.
  3. Enable the root account
  4. Login as the root user and drag desired directories (iTunes, iPhoto Library, Keychains, etc) from the old user account to the new one. We are moving, not copying, the data.
  5. Login as the new user and open a Finder window.
  6. Right click on the new user's Home directory and select Get Info.
  7. Under Sharing & Permissions, click "Apply to enclosed items" (Leopard users will need to click the gear icon first to reveal it).
  8. That's it! If you run into any troublesome directories, try BatChmod for adjusting permissions (BTW, BatChmod can also remove ACLs added to a folder or file under Leopard). You may want to delete the old user account (System Preferences > Accounts) when you're sure everything is good. Finally, don't forget to disable the root account.

Missing Sync for Palm OS won't launch #

After installing Missing Sync for Palm OS 6.0.4 on Tiger 10.4.11, the application refused to launch. Its icon would simply bounce in the Dock for 20 seconds or so before crashing completely. The Console revealed this error:
Missing Sync for Palm OS[335] An uncaught exception was raised
Missing Sync for Palm OS[335] *** -[NSPlaceholderString initWithString:]: nil argument
fseventer did not turn up any clues as to where it might be hanging, so we made a new OS X user account; sure enough, Missing Sync worked fine there. We moved the old user data to the new user account, and everything worked beautifully. For a while.

After another hour or two worth of installs, data migration, etc, the same error returned. It took a nontrivial amount of time to finally isolate the culprit: the new user's Movies folder had been moved to an external hard drive and that drive was unmounted. When Missing Sync launched, it would crash if it could not find the Movies folder (even though syncing movies had been disabled earlier).

One final problem was with the Mark/Space Notebook: the categories imported just fine, but none of the memos. These instructions did the trick: Overwrite your desktop data with the handheld device. The process makes iSync (which normally doesn't offer an option for the handheld to overwrite the desktop) see all of the memos on the Palm as newer than those in Mark/Space Notebook, which it overwrites.

Taking timed screenshots in OS X #

Looking for a simple way to take screenshots at a set interval, I happened upon this solution which relies on cron. Unfortunately, cron cannot schedule jobs in increments of less than one minute, and I wanted to take screenshots every 3 seconds. Adding delay and repeat to the same script did the trick (note that the save directory has also been changed to the current user's Pictures folder):

	set DATE_TIME to do shell script "date +%Y_%m_%d_%H%M%S"
	set fname to DATE_TIME & ".png"
	do shell script "/usr/sbin/screencapture -x ~/Pictures/" & fname
	delay 3
end repeat

UPDATE: Just found an open source REALbasic app called Timed Screenshot (2.5MB) that apparently does essentially the same thing. Haven't tried it yet since the AppleScript solution worked beautifully.

Forget eBooks, Kindle offers free web access #

The Kindle is a swell eBook reader, but where it really shines is in offering free web access anywhere in the U.S. via Sprint's EVDO network. Most reviewers fail to appreciate just how cool this is, instead lamenting over the lack of support for streaming media, etc: Mike Elgan is one of the few who gets it (Don't tell Amazon, but its e-book reader does e-mail, RSS feeds and calendaring), though the true potential is revealed by xkcd:

(Mad props to Josh Sommers for sending this in)

So what can you do with free, anytime/anywhere text-based browsing? If Amazon ever decides to cancel or charge for web access, just tether the Kindle to your computer and you're back online (albeit without the same convenience).

Learn C programming at Harvard for free #

David Malan has generously posted his entire fall 2007 Computer Science 50: Introduction to Computer Science I class online. This includes all video, audio, notes, slides, and source code. One wonders how O'Reilly School of Technology's Learn C Programming and others will fare given this free yet first-class offering. Here's the CS50 blurb:
Computer Science 50: Introduction to Computer Science I is a first course in computer science at Harvard College for concentrators and non-concentrators alike. More than just teach you how to program, this course teaches you how to think more methodically and how to solve problems more effectively. As such, its lessons are applicable well beyond the boundaries of computer science itself. That the course does teach you how to program, though, is perhaps its most empowering return. With this skill comes the ability to solve real-world problems in ways and at speeds beyond the abilities of most humans.

Removing simple watermarks from images #

  1. Open image in SnagIt
  2. Colors > Color Substitution...
  3. Use the dropper next to "Old color:" to select watermark color
  4. Click box next to "New color:" to select replacement color (generally this would be the background color)
  5. Goodbye watermark!
Does anyone have a method using free or open source tools?
UPDATE: CyberDoc and Mike Mills kindly recommended the freeware PhotoFiltre (installer-free version available), which worked every bit as well as SnagIt. It's as simple as clicking Adjust > Replace color and using the droppers to select. Initially, most menu items were grayed out for the GIF I had opened, but Mike informed me of the solution: Image > Mode > RGB color. Thanks to you both!

Henry David Thoreau - Original Hacker #

After leaving the University, he joined his brother in teaching a private school, which he soon renounced. His father was a manufacturer of lead-pencils, and Henry applied himself for a time to this craft, believing he could make a better pencil than was then in use. After completing his experiments, he exhibited his work to chemists and artists in Boston, and having obtained their certificates to its excellence and to its equality with the best London manufacture, he returned home contented. His friends congratulated him that he had now opened his way to fortune. But he replied that he should never make another pencil. "Why should I? I would not do again what I have done once." He resumed his endless walks and miscellaneous studies, making every day some new acquaintance with Nature, though as yet never speaking of zoology or botany, since, though very studious of natural facts, he was incurious of technical and textual science.
—Ralph Waldo Emerson, from his eulogy to Thoreau in the August 1862 issue of The Atlantic

A better NOD32? #

Guy Kirkwood kindly sends word of Prevx Edge, and points out this quote as being especially relevant to TinyApps.Org readers:
Edge has been developed with speed and optimization in mind. The entire program of Edge consists of one executable and one driver. All of the cleanup, realtime protection, self protection, rootkit detection, malware detection, and high-color user interface are tightly integrated into these files, requiring only about 800kb on disk. In the system, Edge only requires one service and one driver to be registered - no other registry keys are required and no other libraries need to be installed, and all user accounts on the local computer are fully supported and protected automatically, even under UAC, with the GUI process of Edge switching between users as they log in.

Installation and un-installation of Edge require only seconds and can take place without rebooting the system and there is no need to uninstall any other security software when installing or using Edge.
The standalone Prevx CSI version is described as a "FREE Malware Scanner", but users should be aware that it will not remove most infections without payment (unlike TrendMicro's SysClean, Kaspersky's Virus Removal Tool, etc, which scan and remove for free). Even though it is a single EXE executable, CSI makes numerous registry and file system changes. Most of these can be removed by running the uninstaller which appears in the Add/Remove Control Panel. has a review of Prevx Edge.

nmap not displaying MAC addresses #

This will be obvious to regular nmap users, but Google did not turn up a quick and ready answer for why MAC addresses were not appearing during a ping scan:
$ nmap -sP

Host appears to be up.
Host appears to be up.
Host appears to be up.
Nmap done: 256 IP addresses (10 hosts up) scanned in 1.373 seconds
I initially just added &&arp -a | grep -v 'incomplete' to get the MAC addresses, but that was rather inelegant (and slow). Finally I stumbled onto the answer in the nmap book:
The -sP option sends an ICMP echo request and a TCP ACK packet to port 80 by default. When executed by an unprivileged user, only a SYN packet is sent (using a connect call) to port 80 on the target. When a privileged user tries to scan targets on a local ethernet network, ARP requests are used unless --send-ip was specified.
I felt the gentle scolding of Holmes ("One more coruscation, my dear Watson ---- yet another brain-wave!") as I realized that most of the nmap examples were from a root prompt - ah!

Bypass Dell Inspiron 1100 battery check during BIOS update #

Installing Ubuntu (or any Linux distro for that matter) on a Dell Inspiron 1100 requires updating the BIOS to version A32 for video to work properly (8.10 instructions).

Unfortunately, the BIOS flashing utility (I1100A32.exe) will halt if it does not detect a charged battery:

Battery must be installed.

ROM update not performed.
Press any key to exit.

Perhaps there are some documented command line switches or arguments? Apparently not:

A:\>I1100A32 /h

 Flash BIOS Update Program - Version A32
 Copyright 1990-2003 Dell Computer Corporation.  All Rights Reserved.

usage: I1100A32

The scanty documentation was equally unhelpful, as were my attempts to reverse engineer the flasher with IDA Pro and OllyDbg. Running strings for a clue to some switch or other proved fruitless as well.

UPDATE 1: I finally found the hidden switches in I1100A32.exe with a standard hex editor - they were "encrypted" with a ROT-1 Caesar cipher!! The first group is from the DOS app, the second group from Windows (both versions are included in the EXE, which can be split using DualEXE Manipulator):


Let's rotate them: $ tr '\60-\72\101-\172' '\57-\71\100-\171'


Additional information on these switches can be found here and here. Don't play with these unless you know exactly what you are doing and are willing to take responsibility for your actions.

UPDATE 2: Didier Stevens kindly updated his open source XORSearch app (which helps uncover obfuscated strings) to support ROT encoding. Usage example: C:\>XORSearch -f file.with.obfuscated.strings

Thankfully, Christopher Muto had posed the following question to back in 2004:

   does anyone know of a way to flash the bios on an
   inspiron 3800 that does not have a battery?

Even more fortuitously, Bill Joy had responded:

   I have heard of a /forceit option when executing
   the flash. Another option I have seen is /jabil
   when forcing it to flash when it thinks it has an
   incompatible BIOS update -- maybe try it if the other
   option does not work?

   Since these batteries are available on eBay for only
   $40-50, it is probably not worth the risk of damaging
   your system.

Throwing caution to the wind, I decided to give the /forceit option a try (readers: do so at your own risk and joy). Lo and behold, the evil battery check was miraculously bypassed! Hallelujah!

Who needs a database when you've got sed and awk? ;-) #

As a simple text-based site, TinyApps.Org is ideal for parsing with *nix text processing commands. Here is a one-liner to calculate the average file size of the Palm apps:

grep -o "\[.*\]" palm.html | sed 's/[^0-9]//g' | awk '{s+=$1}END{print s/NR}'

Let's break it down:

First, grep will return all patterns within palm.html matching an open bracket, followed by anything, followed by a close bracket. The -o option (only-matching) instructs grep to show only the part of a matching line that matches the pattern (as opposed to returning the entire line). This gives us output like:
Next, we'll use sed to (s)ubstitute any non-numeric character with nothing, (g)lobally:

sed 's/[^0-9]//g'

which returns:
Finally, we'll use awk to total and average the numbers:

awk '{s+=$1}END{print s/NR}'

{s+=$1} sums the first (and only) column. {print s/NR} prints the sum divided by NR (an awk variable that returns the Number of Records (i.e., lines) read so far).

And the result is:
This worked beautifully on all of the other app pages as well (osx.html, internet.html, etc) save for one: system.html. On that page, one of the entries reads: "[various sizes]". This is the only instance in all of the app pages where a number is not listed within the brackets. As a result

grep -o "\[.*\]" system.html | sed 's/[^0-9]//g'

displays a blank for that line:
     <-- Note the blank line here
which means that awk divides (in this case) 18729 by 55 records instead of the correct 54.

In order to remedy this problem, we will add a second command to sed, separated from the first by a semicolon:

sed 's/[^0-9]//g;/./!d'

/./!d deletes any line which does not contain at least one character, thus removing the single blank line. Now awk will divide the total by the correct number of lines to arrive at the true average (346.833). The full one liner is now:

grep -o "\[.*\]" palm.html | sed 's/[^0-9]//g;/./!d' | awk '{s+=$1}END{print s/NR}'

Do you have a faster/leaner/tinier method? Or perhaps another interesting one liner? Please share the goodness!

Installing Windows XP on a Sony VAIO laptop with SATA hard drive #

Attempting to install Windows XP from CD-ROM onto a Sony VAIO PCG-3B2L (VGN-FW140E) laptop failed due to XP's lack of SATA drivers. Yes, there are guides like Install Windows XP on SATA without a Floppy which generally recommend using nLite to master a new Windows XP CD with the SATA drivers slipstreamed in. As that seemed like far too much effort, I downloaded the SATA driver from Sony, copied it to a floppy, and inserted it into an IBM USB floppy drive. Unfortunately, the Windows installer did not seem to recognize the drive. Options in the BIOS (F2 to access) were slim; on a hunch I enabled "External Device Boot" and restarted. Low and behold, the installer now recognized the drive! The final problem was which of the dozen or so listed drivers to select (turned out to be "Intel ICH9M-E/M SATA AHCI Controller" in my case).

Two passages from W. Somerset Maugham's "The Razor's Edge" #

"Has it occurred to you that transmigration is at once an explanation and a justification of the evil of the world? If the evils we suffer are the result of sins committed in our past lives we can bear them with resignation and hope that if in this one we strive towards virtue our future lives will be less affected. But it's easy enough to bear our own evils, all we need for that is a little manliness; what's intolerable is the evil, often so unmerited in appearance, that befalls others. If you can persuade yourself that it is the inevitable result of the past you may pity, you may do what you can to alleviate, and you should, but you have no cause to be indignant."

"He is without ambition and he has no desire for fame; to become anything of a public figure would be deeply distasteful to him; and so it may be that he is satisfied to lead his chosen life and be no more than just himself. He is too modest to set himself up as an example to others; but it may be he thinks that a few uncertain souls, drawn to him like moths to a candle, will be brought in time to share his own glowing belief that ultimate satisfaction can only be found in the life of the spirit, and that by himself following with selflessness and renunciation the path of perfection he will serve as well as if he wrote books or addressed multitudes."
