Jscad (not openjscad) is interesting but you can not save file can be found at: http://sourceforge.net/projects/js-cad/

Webcad is a remedial cad program. The one plus thing about is you get the source code which is mostly javascript. You can probably add you own modules if you are so inclined. You can run it in a local machine using a browser or move it to a web server and do the same You can get it at: . https://code.google.com/p/web-cad/downloads/list Included are some screen shots. Webcad was removed from google code.

Was thinking about doing a remote install with MSWindows 10. So I went to the Microsoft website to find out what to do. You need a special program to do the install. Oops if you are not running Microsoft Windows, you can not download the file. So I decided to read the documentation.  In reading the documentation, I find that you need a fully working Microsoft Windows machine to do the install. If I had a fully working machine, I would not need the software. Microsoft Fail. ------------------------------------ USE AT YOUR OWN RISK  Remote Server Administration Tools for Windows 10     Install Instructions         To install Remote Server Administration Tools for Windows 10         IMPORTANT: You can install Remote Server Administration Tools for Windows 10 only on the full release of Windows 10 Professional or Windows 10 Enterprise.         ...

When I first made the following cartoon it was pretty much tongue in cheek. But really when you think about it, it is a blessing in disguise. What if you could localize a lot of the web you use a lot without having to use any bandwidth. Actually we already do it with our local web server now that I think about it. If you were a traveling chef you could go choose a food menu. and from that menu, you could do several things. Such as use several calculators. Such a a food conversion chart. Or even have your recipe book with you. And the neatest of all things you could have a virtual site from the same server to show your clients what they could have for dinner. Is that not all awesome! All from that little server without having to go to the internet.

We are playing flash videos one last time to convert them to ogg vorbis type format.  We are using software like "recordmydesktop" to create new videos. Then on the server you can use code like the following: < video width =" 320 " height =" 320 " controls > < source src =" installapp.ogv " type =" video/ogg "> </ video >

You have lite beer, lite this, lite that. Why not apply the same idea to your computing. Why do you need a big fancy over bloated piece of software just to edit a web page? Well in some cases it might be required, but in most cases probably not. Available for most platforms Vim a lightweight text editor will fir the job I want to do to a tee. Vim looks simple and possibly not very useful, but it is exactly the opposite. You even have extensive on-line help. Even though vim is text based you can do pasting from the gui into it, so it is not completely guiless. But to get back to what is important, we need a light program to do some editing. In this case we want to edit a web page on a remote system without ever leaving our desk. Because vim is light, it loads in quickly thereby saving time. The server we want to access could be in the next room or even half way around the world. Remote access puts it at our fingertips. Let's log into the remote server and fire up vim...

Remember the internet from the ITCrowd? You could build sort of your own version with the RPi-A: You can build your own in"tra"net versus using the in"ter"net. But if you really want to be useful you might want to use a stationary satellite. But then to get world wide coverage you might need several stationary satellites. Do not tell me someone has not already done this. So you get: Getting close to home.  Even if you do not have all that fancy equipment you can still build a private intranet.  A bit dated, but still viable: In part one you will get the basic setup and a few tweaks. http://www.instructables.com/id/Your-personal-intranet-Part-1/ In part two you will get some additional tweaks. http://www.instructables.com/id/Your-personal-intranet-Part-2/ Have fun.

One of the things I like to do is port software from one system to another. That is take the source code of a program and allow it to work on another system. Why reinvent the wheel if yo u have something that works. Just because you have a new and different system should keep from using that software. Coming from a school that says within reason if it is not broke, do not fix it then you know what to do. If I have a perfectly working system why convert it to a virtual machine and not know what the challenges might be. If I did not have an existing system, then off to the races to build a virtual machine. What is this all leading up to. With the terminated support of Microsoft Windows XP.  XP per se is no longer viable. Mainly because of security issues. Everyone says upgrade or chunk the system. Invested too much in the system to lightly just chunk it and like most upgrades old software just no longer works after the upgrade.  So using a virtual machine does not always wo...

Have had several machines that I have used over the years. They are all linux or bsd and all the software is from the standard repositories with no commercial software installed. The RPi is replacing some of them. Spent the morning working on my old PIII web server,  Updated it.  Added a web application or two. Always learning new things with it. Can not believe how much I have done with it. It is basically a lamp server, but we also use it to start ipxeboot linux operating system installs, and as a media/game server. It is sort of our own private cloud. It also runs several virtual websites. http://www.instructables.com/id/Uses-for-your-own-private-cloud/ ) Home made router with a PII class machine that uses compact flash for the drive and a bsd variant for the os. The old Pogoplug converted into a local web server running arch linux. The 486 laptop runs a floppy based Pitus linux to communicate with the pogoplug. The old NSLU2 running deb...

More and more It sites are recommending against Microsoft Windows 10. Per IT news. ( http://www.itnews.com/article/2972298/microsoft-windows/10-reasons-you-shouldnt-upgrade-to-windows-10.html ) The 10 reasons you shouldn't upgrade to Windows 10 10. Ongoing privacy concerns 9. OneDrive regression may not work the same way 8. Missing Media Center and DVD player 7. Not much in the way of Universal apps 6. Key apps, including Mail and Edge, aren’t ready yet 5. Win10’s Tablet Mode may not appeal to you 4. The installer may not be ready for you yet 3. Forced updates 2. Ain’t broke, don’t fix 1. Questions, questions, questions Per PC Advisor ( http://www.pcadvisor.co.uk/feature/windows/should-i-upgrade-windows-10-advice-better-good-3618139/ ) Should I upgrade to Windows 10? Windows 8 didn't get the best reception - is Windows 10 better than Windows 7 or 8.1? How good is Windows 10? Per Windows Central 14 reasons why you shouldn't upgrade to Windows 10...

Having been a Microsoft Windows administrator for many years supporting for the server and the desktop platforms, you acquire a distaste of Microsoft products. 10. No matter how good the virus detection software is it is always one step behind the malware. Have more important things to do than to deal with it, 9. Microsoft Windows 10 is not agile enough to do several roles such as server, router, embedded system, or et cetera without major limitations.Also not user friendly with legacy equipment. 8.  Microsoft Windows 10 is a resource hog compared to other systems. I.E. disk space required. Microsoft thinks they own your computer as they can force a download of software at anytime without your input. Makes disk management impossible 7. There are security issues no matter how safe they say it is, just not convinced. Besides, you should not have to do so many tweaks just to be able to use it. Default should be secure, not insecure. Microsoft Windows 10 does not meet gover...

Before you start, make sure the operating system you want to upgrade to will work on your computer. General steps for operating system upgrade. 1. Backup    A. Save data files and program settings.    B. Make a system image aka duplicate if possible.  (requires special software)    C. Get list of installed files. 2 Get operating system.    A.Traditional method.     1, Download new media. (up to several gigabytes.)         In some cases this could take several hours.     2. Burn new operating system to media.     3. Install operating system,  B. Ipxeboot. (MSWindows may require a special server, but Linux and BSD do not)      1. Boot with minimal media. (i.e. floppy, usb stick, or minimal cd)      2. Downloads and installs minimal OS for install control.      3. Downloads and installs the rest of the OS a...

Couple of definitions first. Some people may disagree with this. Network hub: A network hub is a network device that a single network of the same  media types. but paths are intermingled (obsolete) Network switch: A network switch is a network device that a single network of the same  media types. but paths are separated. Network bridge: A network bridge is a network device that connects a single or multiple network segments of different media types. Network router: A network router is a network device that connects multiple network segments of the same media types. Now to get confusing. Many network devices can be a combination of the above. Take for instance what a lot of people call a router is actually a combination of of a bridge and a router. These we all pretty much know about, but what if we wanted to connect some legacy devices such as dumb terminals so they would have virtual access to the network. Actually they are just acting as an ex...

Goal of this article is to give you a couple of tools to remotely manage multiple systems without having to do all the sneaker support. Managing Multiple clusters with ClusterSSH also known as CSSH. (Parts of this article adapted from: https://www.linux.com/learn/tutorials/413853:managing-multiple-linux-servers-with-clusterssh ) If you're a Linux system administrator, chances are you've got more than one machine that you're responsible for on a daily basis. You may even have a bank of machines that you maintain that are similar — a farm of Web servers, for example. If you have a need to type the same command into several machines at once, you can login to each one with SSH and do it serially, or you can save yourself a lot of time and effort and use a tool like ClusterSSH. ClusterSSH is a Tk/Perl wrapper around standard Linux tools like XTerm and SSH. As such, it'll run on just about any POSIX-compliant OS where the libraries exist — I've run it on Linux...
