Re: [Wlug] Python – who's curious or learning it, or codes it daily, or teaching it, or ...

by Theo Van Dinter

fwiw, I have a background in C and Perl, and had to learn Python for work. Read the ORA Learning Python book, which was ok, I spent time trying to relate Python to Perl (dict == hash, list == array, tuple == read-only list, etc,) and eventually just started hacking on things and have been relatively successful (or at least, I can write stuff that does what I want. ;)) I'm using Python 2.4, so I'm constantly at http://www.python.org/doc/2.4.4/lib/lib.html looking up things, which is very helpful. The basic syntax and starting to do things is pretty easy, the harder part is getting a grasp on the whole "everything's an object" and using that when writing your own code is harder. I tend to not like object orientation (various reasons), but you have to get at least somewhat into it w/ Python because you have no choice.

A thread for sharing by those with interest in or curiosity about Python.

That's a great idea! Somehow, though, whenever I build something like that, to just leave alone to do one job, I end up mucking around with it, too.

Alot of the newer boards with integrated everything really are quite nice. And power efficient and cool. Key things to think about. If it wasn't for wanting room for disks, a Shuttle style box would be a nice idea, and I keep thinking it might make my desktop... Gary> For me I buy discrete devices. And the funny thing is that these Gary> days it's hard to find a motherboard without integrated video, Gary> sound, NIC, etc. So what OS are you running, and what applications are you running with uses all this GPU power? Now I admit my last system, a Asus M2N-SLI Deluxe has a discrete GPU, but I got a Radeon X1250 (in Feb 2008) because it was just one slot and a passive cooler. It's a big performance jump over my old Matrox G450 AGP card for sure! Anyway, I've found that the onboard sound/network to be just fine, dual Gigabit works nicely, and overpowers anything else on the network at this time. Now, back to the core initial question, which was about the vast variety of of components out there to choose from. It's really terribly confusing, and for only a 5-15% difference in performance, you can spend a ton of money. I personally like Newegg.com for ease of comparing systems. I also like the arstechnica.com system guides. They do quite a decent job, esp on the low end. Their god box is silly. They really need to be thinking of a god desktop, and a good server box instead. Also, for a home system, I think it makes alot of sense to build a nice home server, which sits in a corner and serves files, does backups, hosts a development web server, etc. Then having a desktop which you can play with, muck around with and rebuild at will, all without losing your files or home directory stuff is nice.

I'll agree 100% here with Frank, start with onboard and then goto discrete if you need more performance. One thing to think about though is motherboard which put most of the PCIe lanes into one or possibly two slots, because they're targetting graphics (read games). For a more server oriented board, you'd like to have more slots with more lanes, but since various chipsets are limited to how many lanes they can support, it might make sense to have something like 4 1x slots, 2 4x slots 1 8x slot plus some PCI legacy slots. Of course you'll never find this type of board outside a server only type board, which typically costs lots of bucks. And of course you'll not fit into standard cases either.

I'll add that there are a lot of advantages to building with an integrated motherboard. Asus mobos are especially well designed. In fact, most of their current product line incorporates Splash Top, which is Linux embedded in the BIOS that allows you to boot into a basic OS before hitting the hard drive. If you buy one, you can be sure all the components are Linux compatible. My last three builds have been Asus mATX.

You'll learn a lot from installing the OS yourself. Ubuntu is a good choice if you're new to linux, but anything in the top 5 or 10 in the list at distrowatch.com is probably a good choice. The installation procedure is pretty easy these days (on the major distros). Leave room on your hard drive for additional partitions to try other flavors of linux if you want. That's sometimes a better choice than trying it in a VM, because then you get to see how the OS works with your hardware. That tends to be more of an issue when you're using the latest hardware.

Based on the type of problem you are looking to solve someone could steer you toward a choice of languages that try to solve such problems. There are 'introduction to programming' books for most programming languages and in some cases they might be found on line. If one is learning programming as a hobby then I would say learn about the stuff that interests you and follow your nose. Read from books and on line sources. Learn at least one programming language very well. Above all else spend a lot of time writing code - it is a skill after all. I've been meaning to put together a introduction presentation to the python language, but other priorities have my time right now. :-(

Hi all, Thanks for your helpful postings. I'm coming back to ask further help in sharpening issues before me.. I see four now: 1. Understanding the machine Wanting a more general perspective that will help me anticipate and navigate OS issues as they arise. Just ordered http://www.amazon.com/Write-Great-Code-Understanding-Machine/dp/1593270038/… Anyone have reading (book, online) suggestions geared at accessible intro level? More intermediate level? 2. Getting a machine Freedom of choice in the component market is overwhelming. A curse, actually. I'd be losing significant time just learning how to spec a system. In the Worcester area, is there anyone I can pay to put together a machine for me with some bit of craftsmanship and reliability? That way I can have substantially more control over machine quality. Do any of you have a favorite components list? I'd be most interested in a machine designed for silence, and I'm quite willing to study up on that issue.. fan noise drives me nuts when I'm coding. What do you think about this workaround -- http://www.inatux.com/order These are FSF/FOSS people. I can't see a need for a super fast system yet, as I can't say yet where my project interests will gravitate. In light of that, since optimality makes no sense, what machine specs do you think would be “good enough”? Desirable packages to install? And, for cable broadband and live streaming of audio and video, what combination or package(s) of HW ad SW should I ask for. Wired case? Wireless case? 3. YOUR advice for a would be hacker? I wonder how folks in this forum might vary from the following position. Would you prioritize or sequence things differently? “Start out by learning bash, then set up your own Unix environment. This is a biggie. PC-BSD works fine. Learn to use it for your everyday tasks, learn how to administrate it and keep it up to date and secure. Then, when you've done that, start in with Python. Solve the Project Euler problems in whatever language you're learning. Learn which languages are better suited for particular problems. Learn about security in programs, vulnerabilities and how to exploit them. Read other people's code and post your own. Learn the low-level stuff later.” 4. What Linux distribution would you pair with Unix? And, what will I learn from one that I don't learn from the other? Thanks, in advance, for thoughts, reactions, give and take! Brian

Specs & reviews here: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131330 Running on this PC, Debian Lenny (kernel 2.6.26-2-686 Bigmem). I have another PC very similar, same mobo but 2.8 gig AMD processor, built Dec. 2008. This PC has a nVidia Corporation GeForce 8500 GT vid card that came out of a homebuilt monster running twin dual Xeons, in which the mobo fried. This PC runs Ubuntu Hardy (kernel 2.6.24-generic) These two PCs run cool with only the stock coolers on the CPU, and the case fans. Right now it's 65 outside, maybe 70 in here, the motherboards are both 39C and the processors are 40C (mine, using it now) and the other one at 42C. The onboard audio chips work fine under Ubuntu and under Debian Lenny. The vid chip in the one without the separate vid card seems to warm up if I am doing certain video-intensive operations, although this is rare. It runs movies like Youtube videos just fine, but certain online viewers, such as like zoom viewers on websites, seem to heat it up some. I haven't checked to see if the same type of operations heat up the vid card in the other PC. Ethernet chip also works fine, needed no special tweaking. Nothing needed additional drivers downloaded. Setting up this mobo was a little odd at first. It would not recognize an older HP flatscreen monitor, but can see the Acer monitors just fine. I RMA'd one mobo before I figured out the problem was the monitor, not the vid chip on the mobo. HP techs had no clue why this monitor was not recognized, and could only suggest downloading a different driver... not needed with the more recently-purchased Acer monitor. I like these monitors very much. They are 19" -- not too big for the tabletop setup here, yet have 1680 x 1050 resolution, which is hard to get in the 19" monitors. The monitors now cost about $99 to $119 depending on who's selling them. These monitors are also among the few in this size and price range that come with a DVI cable in the box. Greg Avedissian of WLUG built these PCs (among many others he's built), and he may be able to offer further advice. He does a really nice job building these things & getting them running. I usually am running several different apps in different windows, all at the same time. The speed of the processor is very good, and a dual-core is fine for me. I can wholeheartedly say that I am very happy with these PCs. All the components work together very well, and they easily do everything I need. Hope this helps.

On the subject of building systems - Re: PC-BSD, FreeBSD, and iXsystems - anyone know about them?

by David Glaser

It has been ten years since I built a system and I figure I should do it again to refresh my skills. I took a look at motherboards and processor combinations and I was overwhelmed by the proliferation of choices. What I was wondering if I could get the members of the group to share the basic configuration of systems they have built to give me an idea of what I should look at. I want to build a compute/file server. I do a lot of heavy duty software development using the Eclipse IDE and the Java and C++ Development tools. Also, I need to store a lot of data - mostly images. My house is wired with a 1GB Ethernet so I have good bandwidth to access the server. Thank you for any help. -David

Re: [Wlug] PC-BSD, FreeBSD, and iXsystems - anyone know about them?

by E Johnson

Seconding Brian's idea. Build a computer: get a processor and motherboard, RAM, a PSU, a case, hard drive, maybe a vid card. This can be done for 400 or less if your needs aren't terribly big, or if you can reuse a hard drive or something. Then rather than running the various distros as virtual machines, install them in your newly-built computer. Make some extra 10 G partitions on the hard drive, then install a different OS in each partition, keeping your home directory containing your personal files as its own separate partition. Then you can test and compare Linux distros until you find the one that works best for you. There are people in WLUG who can help you through the build process or the installation process, if you should want a consult as you go along.

To add on the previous reply: 1.) FreeBSD is great and I use it in many places, but their current offerings for hosting VMs are a little sparse. QEMU/KQEMU and older VMware versions work, but not much more. 8-CURRENT will run reliably as a domU in Xen, though, so progress is coming. Linux offers you VMware, Xen, KVM, VirtualBox, etc. 2.) You may want to consider saving some money and putting your own system together. They're pretty clearly reselling standard parts (the case is an Antec Sonata III with included 500W power supply, for instance), and unless you *really* need a Core i7 right now, there are a lot of bargains now on high end Core2 Quads and DDRII memory that will last you for a while.

You won't get far if you don't know how to install the OS. It would probably be a good learning experience. Ryan Pugatch Systems Administrator, TripAdvisor

PC-BSD, FreeBSD, and iXsystems - anyone know about them?

by Brian McLinden

I have pretensions of hacker status someday. ;-] They are selling a desktop with PC-BSD installed and configured. I'm thinking about buying their new Apollo rig, http://www.ixsystems.com/apollo and ask them to install some kind of virtual machine software on top of FreeBSD (or PC-BSD) so that I can learn various linux distros running as clients. Anyone know anything about them? Any thoughts or cautions about this approach? Thanks in advance for thoughts, reactions. PS - anyone programming Lisp, write me? Brian.McLinden(a)gmail.com
