A lot of linux utilities are bsd based.

Where I "used to" work, the MS IT mgmt were paranoid as sin. If you knew linux and were good at it, you were silent branded as a hacker and marked for termination.

"Anyone or anything can be touched." an old sicilian saying.
Having the source code does not mean much unless you compile it yourself. Drm is allegedly now in ubuntu, which is just as bad.

It was not exactly that crude. Was lucky enough to be successful.

I use debian a lot and like it, but do not rule out centos (a rhel clone). If you do plan to use MS server, please consider using apache instead of IIS.

Penetration testing used to be called dating when I grew up.

My latest project is to turn a p3 into a robot. Interfacing all the sensors is the complicated part. An education to say the least. I am also doing home automation via the parallel port. xmas lights, antenna rotator, air cannon controller, weather station, and etc.

I usually go to http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search to see an equivalent. Usually other companies equivalent parts are listed also indirectly.When in doubt. I just do a simple web search will do it.

Openwrt has a version for x86. Even works in a virtual machine last I tested it.

Absolute poppy cock, what possible problems will you have with upgrading? On ALL critical systems you’d be foolish not to have 3 year NBD warranties (last time I looked, which was a few days ago when I posted some info on this, the upgrade from 1 year [standard] to 3 year was something like £200)
The only problems I have ever had with Dell systems are as follows, a 5 year old Optiplex I gave to my parents had a motherboard failure which I had to fix by buying a replacement board off eBay.
A graphics card in my friend’s 3 ½ year old Dimension packed in and he tried to replace it with something more modern only to have the PSU issue (not enough power) he couldn’t buy an off the shelf PSU so had to buy a less powerful GPU.
Memory, Processors, GPU, NICS, and Drives can all be replaced just as easily as any other manufacturer. Upgrading disk drives on a Dell PERC Array is as per any other array, replace the drive and rebuild the array.
I do have some old legacy brown dells. They still run. I use them for automation control and local servers. The hd's are beginning to go bad. Since ide drives are the exception now I will either have to gpxe to iscsi or something of the like.
Dells are great as long as you have a warranty. I have seen many many black dells die within a day of the warranty expiring. When I was a tech we would send off for replacement parts just before the end of the warranty even if they still worked to avoid the planned obsolescence. If you have systems that you can not afford to be down, a one day turn around does not mean much. Dell is spending a lot of money in India. Guess where all their support people are. We call Dells, New Delhi's. A lot of good hard working Americans lost their jobs because of Dell moving their operations overseas. Dell does not need our money.

It has to be a program especially made to use MPI and then you can compile and run it on all the nodes. Realistically High Performance Clusters like this aren't really useful for running normal programs, they're much more useful for inhouse scientific simulations and data manipulation etc.
You don't need any disks in your slaves as they boot over the network. Just set Ethernet or LAN or something similar as the number 1 boot option in your boot priority in your BIOS. Then when the slave boots it will check to see if it can connect to your frontend node, if it can it will then download the OS from your frontend node and boot that.
You'll only need an ISO if your BIOS doesn't support booting from the network. In that case then you can use ROM-o-Matic to boot a temporary Linux OS that will then boot from the network.
It can be a bit complicated but once you've done it a couple of times it's really easy.
I love etherboot (boot from floppy) for old systems for almost diskless thin clients.

It is a shame that "What to do with an old computer" thread was closed. There is so much more that could be added especially in the area of home automation.

Still have my old Ipad.

i messed around with this not to long ago but i couldn't find a speech that didn't sound like a robot so i gave up.
I do not use mswindows any more, but was just curious in case someone asked me. We have been microsoft free for over 4 years it seems now. I still have all my old ms licenses including two for XP in case some patent mongering ding dongs want to extort money.

I would agree with MrGrim, and in fact I used to provide on site support for a small private owned business and at one stage they required to upgrade their 3 years problematic server, that was only giving them headaches to new a server.
Point being, I went to Dells website and purchased a PowerEdge T110 Server, the good thing about buying off Dell is that you can customize the specs of your server to meet the business demands and on top of that it comes with 1 year warranty, you could also choose to have on site support, if anything happens.
Whereas if you build the server yourself, you would be liable to anything that happens to it, I never been in this situation myself but i wouldn't want to be in one.
Dell locks you in with their internal footprint, unless things have changed. Wait till you see what the upgrade costs are, then you might have second thoughts. After the capacitor debacle, it would be hard for me to even think about getting Dell.

Episode 8x14
in Hak5
This time on the show Jason joins us to talk DSLR video hacks andhomebrew Google TV. Shannon brings us her favorite portable apps, and
Jackie and Darren tackle your questions concerning secure FTP, Ubuntu
Server, and document stealing with USB Dumper.
Jackie reminds me of RR. Like the greater diversity of this show.

Some of my tech buddies and I are getting together next week (the last week in November) to share ideas. We plan to call it Thinksgiving.

That's pretty much what the two words means, "High Availability". You want to have a system up running 24/7 without any disruptions, so if one server goes down due to technical problems, the remaining servers in the cluster will take over.
For the clients there will be no difference, since its all transparent to them.
Did not mean to put a kink in the works. Most people think hpc is the only kind of cluster and that is not exactly right. Technically you have fail over with the hpc if one node fails, another node will take over. Now if the main node fails that is another issue depending on how it is set up..

does any one else like the episodes shorter like this?
personally id rather watch two half hour episodes a week then one, hour long episode a week. its easier to watch an get on with your day.
Buon natale!
You can always download the whole episode and watch in parts as you have time. That is what I do. Personally I like the longer episodes. episode 814 was only 24+ minutes or so.

Just wondered if anyone used text to speech utilities to convert pdf files so they can be put on media players. I can do it on linux, but I did not seem to find what would do it on older mswindows platforms for free. I have a laptop, so I did not see getting an ereader. Music player is easier to carry around and your eyes are free to look around.
# pdf to text (ascii) pdftotext infile.pdf outfile.txt # text to wave text2wave < outfile.txt > voicefile.wav # test aplay voicefile.wav # cp to media player

High performance clusters are nice for number crunching, but high availability clusters are important if you want to keep a web store front open.

Don't just copy, look at what I've done and see how it works. (It does all files though, not just directories)
#!/bin/bash directories = "`ls -l | ask '{print $9}' | grep -v ^$`" let i=0 for directory in $directories; do echo [${i}] $directory let i=i+1 doneThen comes the task of getting user input and responding to it.
That code does not work at least on my system.

Probably the easiest way to keep it from trying might be to disable the network devices on the laptop while you are recovering. It should not load the modules (assuming modules as it is most likely) if it cannot find the devices.
We like the trk (trinity rescue kit) does more than antivirus.

You could use that, and place some led lights around it to make it look nicer.
This one is kind of cool.
Android Garage Door Opener Source Code?

I have some of it here. You might also check the blog of the author. I have figured another way to do it. the source code is not that important any more.
