Automatic killing of cameras? by Anonymous Coward · 2007-08-12 12:44 · Score: 0 · on China To Deploy World's Largest People Tracking Network

We have the technology to automatically locate a camera and track it with a laser.

Who's going to take the next step and but a device that can autonomously clear all the cameras from a given area? Mount a camera detector/tracker on a autonomous plane, also mount a high powered laser programmed to pulse when locked onto a camera and set it free in the area you want cleared of cameras?

You want to be absolutely sure it is a camera it is locking onto and not someone's eyes (reduce the chances of error by operating at 3am when few people are about) but surely that is solvable?

The scope of "entirely from scratch" by willpost · 2002-10-06 17:09 · Score: 2, Interesting · on LFS 4.0 Released

Your particular definition of scratch involves compiling the C source code.
Some might say scratch could also be:
- Writing it in assembly
- Writing it in x86 machine language
- Flipping the bits on the hard drive
- Re-inventing the C source code

All of the methods require additional tools:
- A tool to take the Hard Disk and provide a file structure, write a boot sector and loader
- A tool with some commands to copy the compiler there
- A tool to take the C source code and generate the machine language binary code

You might find it similar to how mammals develop. As far as I know, most mammals require parents to feed, care, and raise their young. I can't think of any fertilized egg, fetus, or newborn that can survive without the parent to hand down their knowledge (I even heard that the reason we are able to live past 30 is to provide knowledge as grandparents or family/clan elders).

I have thought of one way to completely write the OS with only one machine. A long time ago, the old IBM PCs (and Apple computers) had a key sequence which would break into debug mode. After this mode starts, you would be able to type in the machine code to get a rudimentary system going. Another way would be to get an old ethernet card with a rom chip and burn a startup rom. Then you type in the boot loader.
For example: a bootable ``Hello World!'' program, consisting of just over 100 lines of assembler code.

While 100 lines of code is easy to hand type, imagine typing in the 10,000-100,000 characters for an extremely simple operating system. Then imagine hand typing in the machine code for a C compiler (yikes!), unless you want to hand type in the millions to 100's of millions of bytes of machine code to write a Linux system. There would be another way speed it up if you take apart a keyboard, wire it to a device capable of playing back keystrokes. I started to work on this but have postponed it until better times. I did start out by building Linux from Scratch and it took me 30-40 hours of very patient, slow progress. The complexity of even a minimal Linux is boggling when you jump in, compile, link, and see how much text scrolls by your screen when compiling it.

The advantage to Linux from Scratch is you have the greatest control over the OS. Without your direct control over every detail it won't run, as it depends on your Linux knowledge or following the tutorial to install.

Do TAGS automatically update whenever you add or modify members or methods in a class?

No - they are updated when you run the TAGS utility. If you update the methods/members, it's best to rerun TAGS to tidy up the database. It's often a good idea to run TAGS as part of your makefile so that whatever changes are put into the binary are reflected in the TAGS database.

Yes - with GUD (Grand Unified Debugger) under Emacs, you can interface with whatever debugger you feel like, from gdb, xdb, etc.. You can mark lines in the code as breakpoints, view variables, step, next, and so forth inside Emacs, plus issue compile and connect to process calls. I note that JDE also features automatic jump-to-offending-line with compilation issues too.

Using the Service by gadwale · 2000-03-19 20:16 · Score: 5 · on Workspot Offers Free Web-based Linux Accounts

I am so glad I got that account last week! With the slashdot crowd heading there the two business day rule may change!

Here are my experiences to date:

To those that expect to install something on their computers: There is nothing to install, they use the java version of vnc and the desktop is presented in your browser. In reality, the entire desktop is like a remote screenshot and looks EXACTLY like a debian KDE typical desktop. They let you customize it but I haven't got that far yet! If not for anything else, use this for shock value on a doze machine and have a debian desktop inside an IE window!

They are true to their word on the two business day waiting period.

Since th VNC client is GPLed, you can actually download their changes from workspot.org; this is my next weekend project...

I don't know how this works through firewalls, but if it does, geeks in doze offices all over the world have just been liberated!

The site is neat but has very very little tech info. There is a faq which adds little value and repeated searches on Google don't lead to any other pages about this service, so it looks like a well kept secret... till now!

On a side note, there was a previous article here about wireless ebay on a palm VII using debian and workspot. I never really understood that one and since I haven't figured out how to list archived article comments by score all I can tell is that the trolls haven't changed much! I think it talks about workspot using debian to provide wireless access to ebay on palm vII!!!

The other cool thing about this service: If you have a license or the software is free and does not require root, you can install it! Can't wait to get the emacs JDE from installed and running so that I can use this site for (*new buzzword alert*) 'remote coding'.

If this site is really for linux newbies to try it out, more info 'bout how to get started would definetely help...currently the site only lets you escape the hassle of installing linux ( not that much of a hassle anyway ) but does not serve as an intro to linux.

Whats with the bannerless CGI enabled apparently limitless web space (faq says don't use _too_ much diskspace, open to interpretation...)? These people seem to have all the goodies on one site.

I tried to ftp out of the box to move my website in but sadly nothing happened! I realized how helpless I was without having the box at my feet: there was none of that reassuring hum from the drive as you clicked on something and waited. How about a flashing [processing command sire]...? Now that would have geek value!

Re:PKI and other issues by ninoles · 2000-02-24 03:30 · Score: 1 · on SSH v. SRP

After reading your e-mail and ssh/srp comparison, I even more appreciate the way the Debian project (will?) handle it:

The ssh authorized_keys is manage through LDAP. If a maintainer wanted to modify it, it should use its official GPG key to encrypt the files and mail it to the ldap server. Because the key is well trusted (it must be sign by another maintainer), we obtain, IMHO, a secure way to exchange keys, which permit the use of RAS-based authentification.

For sure, the Achille Heal is on the Debian Key Ring. If it became compromise, the validation is no more valid. However, as I said, each key who aren't in the original key ring must be signed by someone else already in the key ring *which has met* the developper physically. Moreover, the key ring is manage by a person who can verify the authenticity of any demand and the keyring is widely distributed through the standard distribution.

It seems, when reading the comparaison, that ssh is as secure as srp if rsa-based authentification is used. So, for the Debian Project, SSH is as secure as SRP. However, having an yet another open source alternative is a Good Thing(TM) and one of SRP goals is to be a standard interface for authentification, making it easy to incorporate into other applications. OTOH, I really don't know if it's hard to add ssh authentification into an application. Can someone could give me some examples of applications doing so (both ssh and srp) which is not an ftp or telnet client?

Thanks and sorry for my bad english, I'm just a bit tired.

Don't forget these as well:

ET-Linux - Runs on embedded x86 systems, and really IS meant for small, embedded systems (eg. little to no security). glibc2.1/kernel 2.0.38. Used with an ADC card to acquire data in the astrophysics lab where I work. It'll fit nicely in a 6MB flash chip.

TINY Linux - Really meant for recycling old 386s, works in an embedded environment without too much work. A full install with X takes around 80MB, but you can pare it down to 10-20. Based on libc5, though, so watch out when compiling new packages.

MicroLinux - I haven't used this one, nor do I read Russian (which the page is in), but I've heard that it works and has a very small installed footprint.

MuLinux - An Italian distro, still in development, major feature of which is the ability to live in a ramdisk on a computer with only 4MB of ram, if I understand correctly what I've read about it. (Haven't actually used this one either.)

Re:Centralized Searching is the Wrong Approach by Grail · 1999-12-14 08:19 · Score: 1 · on Is the Internet Becoming Unsearchable?

What you're talking about is search brokering. Basically, you have one server which acts as a "broker" (or a Meta-Search engine, if you will). It sends queries out to search engines and collates the results.

The difference between brokering and meta-searching is that each of the search engines in a brokered system categorise and rank their results in a consistent manner.

Thus the brokering engine can return you a list of results that is meaningful.

The protocol can be simple HTTP. Instead of indexing a remote site, you just call a standard URL such as http://site.name/cgi-bin/broker-server?...

The arguments/parameters for this search could be based on the fields used in Dublin Core (or just skip to RFC 2413 - Dublin Core Metadata for Resource Discovery). However, Dublin Core is quickly being converted into a really complicated library-style cataloguing system. Perhaps something else exists that suits the purpose.

My experience of UMSDOS linuces... by teraflop+user · 1999-09-21 19:58 · Score: 1 · on WinLinux 2000

I bought an obsolete laptop, and the first thing I tried was putting a tiny Linux, muLinux, on it. muLinux will run from floppy (4 of them if you want X, gcc, and network tools), but can also clone itself to create a UMSDOS installation or a loopback installation (this latter is a Linux filesystem inside a big file on the DOS partition).

The UMSDOS clone worked OK, but the problem is that Linux needs thousands of tiny little files. These are stored rather inefficiently under UMSDOS, and become a nightmare if you need to defrag (for example to partition for a full Linux distro). The performance hit is also noticable. (Notice that WinLinux2000 occupies 500Mb on a FAT32 partition or 1Gb on a FAT16 partition - that is the impact of all those little files).

My guess is that the loopback filesystem, as used by Mandrake's Lnx4win, is a better choice. Hopefully the WinLinux people will add this option in future. Otherwise, a great piece of work - I love the idea of stealing all the settings from Windows.

Also worth looking at is DemoLinux, which runs off the CD.

My laptop now runs Slackware 3.4 in its own (half empty) 120Mb partition, with X, compilers, networking and freeciv. I might try Debian 2.1 if I need libc6.
