I mentioned getting newLISP working with twitter in passing on HiR, and it came up to use wget when you need user/password pairs for HTTP Basic Auth. I came up with this to create a working Basic Auth header for get-url. You must set 'url 'user and 'pass first, obviously. (set 'hedr (append "Authori...

I posted the following article. Thanks for your help, guys!

Awesome, I didn't even think to AND it against 0xffffffff even though as part of this calculator I will have to AND the IP against the netmask to come up with the network address, so I'm not sure why that logic did 't come to me earlier.

That helps leaps and bounds.

I'm having some trouble figuring out some stuff. The first thing is netmask. If I have 192.168.0.49/24, I'm tempted to try this to turn /24 into a network mask: (link posted to log because I can't get the code to show up right) http://stuff.h-i-r.net/nl2.txt How do I limit hex to only 32 bits (i.e. ...

I'm wondering if anyone has bothered to mess with the Google Data APIs, specifically Spreadsheets . I'm kind of at a loss for where to get started. Zend Framework has a class for PHP which I've managed to figure out how to use, but that's pretty much cheating. Basically, once you authenticate and ge...

I worked with Lutz for a few months, and I've been hooked ever since :)

I turned 0x1c years old today. And I feel every bit of it. Ugh.

The Trek Store is near Kansas City, in Merriam. It's about 2 miles west of the office complex where Kozoru used to be. For whose who know the area, it's a few blocks east of Neiman and Shawnee Mission Parkway. Tomorrow is the beginning of Bike to work week, and I'll probably put about 60 miles on my...

I rode from downtown KCMO on my bicycle to the Trek Store near where Lutz and I used to work. Trek Store hosts a monday night group ride that's nice and slow, and loads of fun. Looks like I got busted wearing my NewLISP shirt in public again! I'm pretty much right in the middle of the picture: http:...

Hey Lutz... I'm just about ready to move to Wholesale Internet. They're a competitor of NetStandard. Their main data center facility is downtown KC, and I'll have physical access. I think you can get off the ground with a colocated (not dedicated) box for about $40 per month with 100GB transfer. I'd...

nice blog, ax0n. Keep it up! In my experience, starting a blog is easier than keeping it going... :-) I've been keeping this one up with an average of two posts per day on weekdays. http://kc-bike.blogspot.com/ And prior to this blog, my friends and I that are writing on this blog kept a bi-monthly...

That's nice, I'm actually using OS X most of the time. I didn't realize it had that feature. And actually Wietse Venema (I think it was him) said that absolutely no software could ever recover data that was simply overwritten one time. Data recovery methods beyond that scale have to occur on an elec...

Actually wiping data can be quite complex e.g. see http://www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/ . And smart drives with cache and file systems that will sideline old data and write a new block under some conditions are problematical. It depends on how secure you...

Here's the code I'll be using for my next article. It works the same but is more compact, with all of the core logic on one line, and a second line to write the pad remainder file out. #!/usr/bin/newlisp (set 'params (main-args)) (if (< (length params) 5) (begin (println "USAGE: crypt.lsp [pad] [fil...

Is there any way to securely erase a file in place with newLISP? I mean, a way to access the actual blocks on the device to make sure that you are over-writing the location where the file was stored, instead of simply making a new file with the same time?

... this is the commandline utility I am using: #!/usr/bin/newlisp (set 'fname (main-args 2)) (print "Passphrase:") (write-file (append fname ".enc") (encrypt (read-file fname) (read-line))) (exit) Because it is XOR based it works both ways for enryption and decryption. Lutz I wasn't sure how encry...

I actually have an update to that article that I plan on posting tomorrow. The article is done, but I'm pacing myself. This can take a very random piece of key data (such as a file made from /dev/urandom output) and can encrypt simple plaintext or binary content (images, executables, etc) without a ...

My old crew (HiR e-Zine from back in the late 90's) has set up a blog. http://h-i-r.blogspot.com/ We've been discussing (in an email thread and at the recent 2600 meetings) cryptography, specifically the XOR variety that's simple yet powerful. I decided to write a quick little newLISP tutorial. I am...

Hey guys. That was my article. 2600 says that once an article gets printed, the author may do whatever they want with it. This is the fourth article I've had published, and as usual, I've posted it publicly. The whole article as well as friendly downloadable code samples are available at the link be...
