From TFA: "The news will be a massive blow to the many companies who are making these cables, but the HDMI does point out that those cables with a DisplayPort socket on one side and an HDMI female receptacle on the other (essentially a dongle) are okay. This is because a licensed HDMI lead can slot into them."
Monoprice and the adapters apple sell are fine. The cable may be more convenient, but in most cases, its a non issue id think.
the summary should probably read "I make the case in MAKE magazine". honestly, the case isnt very conclusive in the article, just really a story on how someone tried learning chinese.
Use virtualbox and fedora or ubuntu, two of the most common distributions around. Virtualbox (or vmware or parallels or whatever) is a smart choice - she can't fuck anything up during the installation, can easily try multiple installs and what not. Snapshots are cool too.
There are an awful lot of sharp peaks in power consumption - I'd like to know how many runs they averaged their points over (i'm guessing it was all a single run, but i cant find the data on this test). Also, no specific hardware drivers other than the graphics driver were installed is a non-representative case on windows, where most manufacturers provide extra drivers and what not to give more features/ different power consumption. And finally, these are awfully high end machines - why not test something a normal person would have (i.e. a netbook, a 300 dollar laptop from [insert office store here], a 500 dollar desktop from [insert office store here], etc.?)
it says these are the blob ones and the opensource ones give higher power usage on the first page.
and a good portion of science and engineering graduates don't end up in science and engineering.
I see a lot of "Use linux, its the way to go" type responses. However, you're going to lock down the systems a bunch anyway - its a school. If they're programming, big freaking deal, they can always use cygwin, they aren't going to be doing kernel hacking or something on school computers unless if its in a virtual machine type setup. What do your tools which your users are already comfortable run on? Windows? Then run windows - theres no reason to screw people over with a switch unless if it will improve something. Students will have to learn different interfaces anyway at some point, so its not going to kill them - they may as well get some concepts down beforehand rather than presenting some specifics. If you want to teach them about linux, you can always setup virtual machines or ssh into some boxes setup for this purpose explicitly. The users are probably comfortable for the most part in windows as it is, and frankly, they're probably going to be sitting around in gnome or kde on linux anyway, which really, theres about a 15 minute transition time tops, aside from keyboard shortcuts which, really arent important.
Editors like vi(m) & emacs clones run on windows, so thats not a big issue either. And most of the software has alternatives anyway that can coexist with the ones you're using right now, i.e. visual studio and eclipse for some cases, scilab and matlab (though matlab is far preferred in my experience), etc.
And what about solidworks? doesn't run on mac os x natively. gotta bootcamp/parallels it.
These kids are probably going to college anyway where they'll see more appropriate tools of the trade anyway. Their coursework shouldnt really be about the OS they're using, but what they can do cross OS. ie. even if you're on a windows machine, you can teach them shell scripting through cygwin, and the concepts will carry over to windows powershell or with some simplifications to cmd. Or, you can teach them how to code in C++ using visual studio as an ide, do a lesson on makefiles and they can move to g++ when they want - its more important that they know good C++ though (i guess people are using java here now though).
they'll eventually be dropped in an unfamiliar environment anyway... may as well teach things that are more general than what OS they're using specifically. And a lot of things can be done that make sense cross OS anyway thanks to virtualization and things like cygwin. And you don't really want to make students unhappy by switching them off something they're pretty comfortable with already for no good reason - you have wonders like X forwarding and what not which can help.
From my experience, companies like Dell have better support for large deployments than Apple (and more modern experience with this sort of thing). So the hardware would dictate windows (or linux, but im against that unless if its virtualized or dual booted). You can get all 3 with mac mini's or other mac hardware, but a recent OS shouldnt make too much of a difference in a high school setting (ie. win xp, vista, 7, a recent fedora/ubuntu/centos/slackware/etc., os x 10.3 or above, etc.).
Just because they use the same BLAS/ATLAS backend doesn't mean that they'll perform to the same speed - BLAS calls dont have to be done at the same efficiency, or certain common operations which are a chain of calls be implemented in the same manner. A lot of good functions are prewritten for Matlab. It is like saying if I put a Ferrari engine in a Chevy Suburban, it will perform as well as if i put it in a Ferrari.
The . in matlab is very helpful for doing things like [1 2 3]
You can run the following to find what it supports:
>> methods int64
>> methods uint64
Compare to
>> methods int32
>> methods uint32
Though floating point is very common for matlab use, i think this was fairly common knowledge.
Until someone makes an alternative with all the toolboxes i use, im not switching.
They probably just missed it this time.
In a few years we'll have http://www.youtube.com/watch?v=ycM844Bfzsk , though imo this is quite silly.
strange. maybe you should try it on a newer version - vmware does it beautifully.
Hackers of the world, unite!
