Re:Well it works and it's not new
In the '60 electric freight trains were used a lot. like this rail in Turin, used only by FIAT freight trains, and still used in the '80s (note the Fiat Ritmo that were carried).
In the '50 in Italy were used electric lorries using overhead wires powered by an hydroelectric central that was an hack made because the road was steep for the engines of the time and for the electric company, electricity was cheap.
For public transportation the problem of electric vehicles was solved more than 100 years ago with trams. Start to put back tramways and overhead wires for the trolleybuses, this could be done now, with proven technologies. It's not hip for a millenial, maybe. -

Shrayer, without the cShrayer, without the c. There's a photo of him here: http://www2.polito.it/didattica/polymath/ICT/Htmls/Studenti/Universita/Tesi-DAlessandro/Quei%20favolosi%20anni%20'70_file/image070.gif
I crossed paths with Michael many times, most recently at a resort in Southern California in the early 90s.
Earlier than that when I ran a TRS-80 software project at Programma International and we released a product named Pencil Point which added inline formatting (similar to what later became HTML) based on codes I'd used on earlier Alphatype and CompuGraphic typesetting systems.
Before then, Electric Pencil was strictly wysiwyg. I started development on Pencil Point before merging my Practical Applications company with Programma International, after meeting with Arthur Schawlow (yes, that Arthur Shawlow: http://en.wikipedia.org/wiki/Arthur_Schawlow) who was working towards getting Stanford University to switch from expensive Wang word processing systems to using the TRS-80 Model One with a hardware hack to enable lower case.
While that project never caught on (probably because of the required hardware hack), Shawlow was definitely ahead of his day, as was Michael Shrayer.
Michael was a cameraman (I don't remember whether for television or film) when he wrote Electric Pencil. Based on conversations with him, I believe he never really earned that much money from the project. I don't believe he was ever a millionaire.

Re:Video streaming?
Right, so I've been searching and the FSF Europe has been using live streams more than the FSF. They reference "...the Free Software activists of the Politecnic University of Torino, though, who volunteered to use their Free Software video streaming software to stream the entire sessions live, and who will be offering recordings of the sessions online..." in all the places streaming is referenced.
This seems to be a reference to Feng, a "... multimedia streaming server compliant with the IETF's standards for real-time streaming of multimedia contents over Internet. Feng implements RTSP - Real-Time Streaming Protocol (rfc2326) and RTP/RTCP - Real-Time Transport Protocol/RTP Control Protocol (rfc3550) supporting the RTP Profile for Audio and Video Conferences with Minimal Control (rfc3551)." Maybe the FSF will use the same.
Then again, maybe they'll stream it in RealPlayer :) -
295 km in Italy
let me also share this record (announced also 24 may in in this Italian newspaper): the Ixem team of "Politecnico" in Torino has set up a 20megabit connection from "Capanna Margherita" (Mount Blanc, 4556m of altitude) with "Pian Cavallaro" (a point on the mountain range that divides Tuscany from Emilia-Romagna); the two points were 295km apart; the hw used was a 386 CPU running Linux; the network is Hiperlan type 2 and Wi-Max 802.16 (EIRP regulatory requirements limited to 30 dBm is satisfied). They have also set a webcam in Capanna Margherita, that is accessed thru the link

Re:Dispelling some more FUD
I haven't done or seen testing of both, but I have heard FreeBSD is a bit faster. Of course, that is not based on the crap Opperman says.
Oppermann said Linux can't do much more than 100Kpps. He didn't even qualify that statement with the type of hardware, he flat out said Linux couldn't do much more than 100Kpps.
The poster said he had Linux doing 1.3Mpps.
here is one showing Linux doing about 500Kpps on practically identical hardware. So I wouldn't trust anything that troll Oppermann says about Linux.
By the way, there is a patch for Linux floating around that implements packet prefetching for the e1000 driver (something that BSD does) which allows it to push 60B packets at wire speed and would surely help with routing. Unfortunately it also exposes some hardware bugs, but FreeBSD typically trades off speed for stability. Linux doesn't have that luxury, unfortunately.
Oh, another thing, FreeBSD is only faster when doing fast forwarding between interfaces (Linux doesn't do that). If the host CPU actually has to examine the packet, then you can't do fast forwarding... and FreeBSD is slower then. On a real world router, you usually can't do fast forwarding. -

Re:Wrong question?But I need to be able to reliably record multi-track audio at low latency and high resolution, burn cds simply, and be able to LISTEN to music on my computer with xmms or a similar winamp clone.
Some programs to help you:
Ardour - A program designed to record edit and mix multi-track audio. Now my use of audio recording/editing experience is strictly armature but this seems to be a pretty good Cool Edit/Adobe Audition like program when comparing feature lists of both(excluding the new additions by Adobe that allow you to work with video).
K3B - this is one of the best CD/DVD burning programs Iv seen on any platform.
Freeamp - a program similar to winamp and XMMS in look and feel.
amaroK - Another audio player, although this player does not shrink to a compact size that can be place out of the way. It does, however, shrink to an icon in your utility bar in KDE.
-
My Windows ListUser interface, Windows system, Internals...
- Aida32, hardware display and diagnotics
- CoolTaskBar to sort out the mess (particularly in Windows 2000)
- FreshUI, tweaking utility
- TweakUI, same as FreshUi, but different options, these two combined give you a lot of different options.
- PowerToys, tweaking utilities. In particular the [Send file name to clipboard] and other options which I cannot work on Windows without.
- Get everything from SysInternals, a ton of wonderful stuff here, too much to mention, but will let you track every file access, every registry write, every debugging message. Tons of great command line tools too. For instance, ever wanted to delete a file only to get a "There has been a sharing violation. The source or destination file may be in use" message ? Where Windows doesn't even know for sure if the file is in use or not. Get Process Explorer from SysInternals.com and type the file name in its [Find][Find Handle] menu. Close or kill the appropriate process if necessary.
- Desktop Manager or FlashDesktops, gives you 4 desktops just like on Linux.
- Alt-Tab Replacement, Gives a screenshot of window Alt-Tabbing, useful when you have multiple unsaved docs open, etc...
- OpenCommandWindowHere, right-click on folder option to open command prompt window at that folder, useful for deep or complicated folder names
- Memstat XP, lets you monitor memory usage in tray, small and simple but not that useful.
- NetMeter, lets you monitor network usage in the tray, small and simple but does not seem to work on all types of network interfaces. Online Eye Pro works better and has lots more options, it's based on WinPCap just like Ethereal (see below).
- TrayMeter, lets you monitor cpu usage in the tray, small and simple.
- WinRAR, unzip anything you want, supports tar.gz, zip, rar, arc, and much more.
Network Utilities
- Xmanager, excellent X-windows manager.
- FreshDownload, Download Manager
- ssh, scp, wget, rsync... comes on CYGWIN
- Putty (and friends), ssh client and other utils (but ssh is part of cygwin and works just as well)
- WinSCP, a wonderful SCP/SFTP client for windows (scp is part of Cygwin but this is easier to use)
- NetScanTools a GUI interface for most command line tools also found in cygwin
- WebDrive, mount various types of network protocols (ftp, http, ssh) as local drives, buggy but useful (RiverFront)
- POPfile the best spam remover I've found so far (works with outlook express and any app)

Re:Cygwin, MS Services for Unix?
Actually according to the coLinux installation page, it uses cygwin1.dll which is the CygWin api library that translates linux function calls to windows function calls.
It also uses the WinPCap kernel level packet library to directly access the network hardware layer in windows. -
Re:Ethereal and/or tcpdump
while tcpdump is afaik a Linux-only tool
No, it works on many other UN*Xes (on at least some of which it ran before it ever ran on Linux), just as Ethereal does, and it even works on Windows, as long as you replace "tcp" with "win"
:-) - WinDump is a port of tcpdump to Windows, done by the WinPcap developers. -
Re:Ethereal
Yes yes, your statement is more accurate. I just usually think of the filter string as being part of tcpdump, and you can use that within ethereal. But yes, even that is really handled by libpcap (or winpcap or other variants, if we're getting super-specific... not that we should be, because I've certainly made some mistake in this post that someone would want to knee-jerk respond to).

Ethereal + other tools works nicely
I use tcpdump UNIX-side, and Ethereal Windows-side. Personally? I find Ethereal hard to use, but it gets the job done. I've traced down bugs in OpenBSD TCP stacks with it on my production servers. I've tried half a dozen other packages but they didn't add enough value to make them worth trying to hit my boss up for cash.
To install Ethereal, you will need to download and install the low-level WinPcap driver.
And you may find the Ethereal packet analysis plug-in Packetyzer helpful; sometimes reading raw logs gets a bit annoying.

Re:I use AVG + ZoneAlarm + Ad-awareFunny thing about Kerio is that it works by hooking calls into wsock32.dll. You can write a simple program that does not use winsock and it bypasses Kerio.
Download winpcap. Unlike Unix libpcap, it includes both functions to create packets as well as capture them. It does not use winsock but rather installs an NDIS driver that sits lower in the TCP stack. You can then write a simple program that listens for packets and then manually constructs packets with UDP/TCP headers and sends them out. Completely bypasses Kerio.
If you'd like, I can post the code. I tested this about a month ago and it worked against the latest version of Kerio Personal Firewall. Took about an hour of work for a proof-of-concept program. You could get really crazy and implement a TCP stack in userspace and then write all kinds of trojans that would bypass TPF. Only works with privileged accounts since you need permissions to install an NDIS driver, but outside of controlled corporate environments, all Windows users use the Administrator account anyway.
Sygate and ZoneAlarm both install low-level NDIS drivers and are not susceptible to this attack. (At least I couldn't figure out how to bypass them - it may be possible to install a TDI hook which sits below NDIS, but this looks like months of work.)
Other than that, TPF really is much nicer than Sygate or ZoneAlarm, but this is a pretty gaping hole. I'd recommend Sygate over ZoneAlarm.

Re:Unintentional Consequence?
No, the whole development process involves lots of randomly-generated code being run, after which the best-performing chunks are gathered together, randomly modified umpteen different ways, ALL of which are re-run. After some number of iterations, the result is distributed as the latest driver. It is already known that genetic algorithm development can lead to things that work great, but nobody can understand how (especially with respect to hardware device development). Here is a link to a whole bunch of papers on the topic.

Re:If you wanted to...

can't reproduceI can't reproduce this behavior on my Windows box running IE 5.50. The blog article doesn't say which version of IE is supposed to have this behavior.
Try it yourself -- use windump (tcpdump for Windows) to capture the packet trace.
Report back, share the news. I don't think there is a real "request" packet as mentioned in the blog article, but would sure like to see it. If there is such a packet, perhaps it's Transactional TCP (RFC1644).

Re:Exactly.Hmmm...either you're talking pounds and I don't know the exchange rate, or wages are seriously depressed for my overseas brethren...I'll keep that in mind before my move. =)
Not too familiar with strace, but there is an strace for NT (Alpha build, don't use on production servers according to the notes). Also, Sysinternals makes some good utilities for debugging...which, once again, I don't get into. I'm not sure why having the source code would allow me (a non programmer) to see what the application is doing internally any more than I can deduce what Windows is doing internally by looking at external events. Oh, and tcpdump is also available for Windows as WinDump (bonus points for being BSD licensed).
I've never reinstalled a Windows Server because it couldn't be fixed. I've reinstalled because of hardware failures, misconfigurations or upgrades, but that's about it. I have, however, reinstalled Windows desktops because I didn't want to take the time to fix them. Like I said, though, if I can fix it about 2 hours with a reinstall, it's a better proposition than spending 4 fixing it.
Windows the OS is very stable...it will run on decent hardware for just shy of forever. Windows apps and assorted device drivers, however, are all over the place in terms of stability and are the cause of virtually every BSOD or crash I have ever seen. I do wish Windows had a better model between device drivers and the kernel, but then I don't run flaky drivers on servers...that's more a desktop concern. Flaky apps should be fixed by the vendor or changed to a competing app.

Re:Generally Good, One Oddball Problem
I would recommend running a program such as Linux TCPDump, or WinDump, the Windows port and see what the traffic is. If it's NetBIOS or something of that ilk and you are running Windows, then not only are you inconvenienced, you are at risk of other folks exploring your network neighborhood, etc.

Re:Other sniffers
Analyzer is the way to go. Free, open sourced, and really nice UI.
If you're using Windows, at least.
You'll need winpcap to get it to work right.
You'll need WinPcap to get it to capture packets at all - but you'll need WinPcap to get Ethereal to capture packets on Win32 as well.
The Politecnico di Torino folk also have WinDump, a port of tcpdump to Win32, also using WinPcap.
Search for it on packetstorm.
Or just go to the Analyzer site (I'm assuming from the reference to WinPcap that you're talking about the Politecnico di Torino Analyzer). If the site isn't up, try again later.

Currently the freeware version of Optout only can detect and remove Aureate/Radiate/Binary Bliss (advert.dll) spyware. However, this type of spyware is embedded in hundreds of freeware products.
If you're looking for a utility to detect all Spyware, you will have to do it yourself using a program such as tcpdump or windump.
