Anyone here used Open Web Server (FKA Sun Web Server) before?

Good God is it confusing. Especially when you're fiddling with an existing set up.

Someone come to Winnipeg talk about some Linux gadget or tool. Our UNIX user group needs more presenters & demonstrators.

//just putting it out there, on the off-chance...

I can't easily visit but if you need a "gadgets and tools" recommendation to talk about, how about GNU Screen?
 
  2010-12-12 12:55:03 PM
This may be too specific, but anyone got any recommended reading on artificial neural networks an research in the field (mostly anything pertaining to simulating neural networks)?
 
  2010-12-13 05:55:42 PM
Barakku, I have a pdf book on Machine Learning that I can post for upload for you.

As for supplementing, all I can say is beef up on advanced statistics.

Mike: I can't easily visit but if you need a "gadgets and tools" recommendation to talk about, how about GNU Screen?

We just did screen / byobu / tmux for our "RTFM" topics in September, but it's impressive you're on the same wavelength :)

So Donald Knuth is coming to visit my university for a Q&A session in February. I don't know all that much about him, but have asked for The Art of Computer Programming for Christmas. Any ideas on what to ask?
 
  2010-12-14 01:10:38 PM
I hadn't heard of byobu...reading up on it now.
tmux I've been meaning to play with a bit to see what's different between it and screen.
Screen is absolutely essential for the way I work though -- I've used it every day for about 15 years now.

I just finished rewiring the switches and light in my aquarium. I should have done that instead, and mess with the fish.
 
  2010-12-20 06:16:13 PM
Check adafruit, they have smaller strings of RGB LED's available that might be easier to work with in an aquarium setup :)

Hey Mike, why not take about 100(or bunches more) or so of those strips, lay em side by side on the roof and voila, instant video. The possibilities would be infinite, messages, pictures or even whole videos. Just remember to not watch porn while connected up to it.
 
  2010-12-20 09:53:57 PM
The main reason why not: $30/meter :)
 
  2010-12-20 09:57:34 PM
Power draw is another... Just the 5 meters I got peaks at about 3.5A at 5V, ended up using an ATX power supply since I couldn't find a wall wart that beefy.
 
  2010-12-21 05:59:32 AM
Sounds like some of you might like Project Blinkenlights.
There are several videos of it on youtube - this, for example.



I remember a couple of friends and a hardware guy building a programmable "blinkenboard" with little LEDs and a Linux driver back then; they had it mounted to the wall and connected to the "corridor server" in their flat.
It isn't linked in the blinkenarea's projects section, though; only an archive.org reference under links

Stuck on a mac for today. Using safari. How do I see where a link goes? In firefox on Unix I hover over a link and the target appears. In safari I hover and nothing happens anywhere I can see.

Thanks, Mike. Is it on by default? I may have turned it off years ago without thinking. I come from an era when the web was young and status bars were always full of annoying javascript flashing and scrolling messages.
 
  2010-12-21 01:14:19 PM
Don't know.

Most Javascript implementations don't support updating the status bar text anymore, because phishers were using it to hide the real destination of links.

Nope. It really should be.

I feel like I'm working with heavy gloves on. There's layers and layers of applesauce between me and what I'm trying to do. I hate click to type. I hate non-multitasking UIs. I hate it when applications work around the single-task UI bug by bouncing to demand my attention RIGHT NOW for something that can wait.

The good news is, the display is sharp and by fighting hard enough I can often get iTunes to play the music I want.

I'm looking for a compiler. This mac has some xcode stuff in /Developer but it doesn't work from the command line due to path search problems. The non-Apple gcc installed elsewhere doesn't work because some files are missing, probably wiped in the last OS update. Is there a trustworthy binary distribution of gcc I can use at least to build a newer gcc?

Something non Mac-ish.

My niece needs a Christmas present. What's a good science, or at least non-fiction, book for ages 8-12? Fun, with pictures? Cool or bizarre animals, maybe.
 
  2010-12-21 05:57:07 PM
Get the latest Xcode update from Apple's site. I haven't had issues with $PATH keeping the Apple gcc from working.

I finished school a little while ago, and just got a job offer I accepted today. The pay is ok, but the benefits are exceptional... like WAY beyond exceptional.

One of the perks is that it's at a private school, and I get two months off in the summer in addition to the three weeks of vacation and four-day long weekends. I have the option of sitting on my arse and collecting EI, or I can fill up my time with other things.

Any of you experience peoples have an idea of extra work or contracts that can fill up absolutely no more than two months during the summer? I know it will depend on what's available here, but I'm curious if you have some interesting ideas I haven't thought of.

Professional, I mean. And PG. Oh, behave yourselves.
 
  2010-12-24 02:19:30 AM
There are 3rd world problems, 1st world problems, and "my custom Christmas lights have an integer overflow bug" (now fixed) :)
 
  2010-12-24 02:20:37 AM
Congrats on the job ;)

If I had 2 months of no work in the summer I'd probably spend it with a soldering iron in hand, or a guitar in hand, or maybe both.

Do some summer stock?
Rafting guide?
Tutor the little rat ba.. er students over the summer
Tour guide?
Cruise ship entertainer?
Do Podcasts?
Continuing education and get a higher degree?
Spend 2 months on the beach in the bahamas?
Scuba instructor?
Write a book?

Well, I might go on a road trip with the new husband because we haven't been able to have a honeymoon yet. Probably renovate the bathroom too. But $ and furthering my resume and work experience would be nice.

Got a tech problem, folks. I'm on a borrowed computer, and there's something wonky with the settings. For instance, when I look at the Fark main page, everything displays except the tags (Florida, Sick, etc.) In phpbb boards, things like the Quote and Warn buttons don't show up.

This happens in both IE and Firefox. Anyone have a fix?
 
  2010-12-30 12:29:17 AM
Mike probably has a better answer but as far as I can tell that may be a java issue. They use the class atribute for displaying those tags.

<td align="center" width="38" nowrap="nowrap"><span class="ttag topic02"> </span></td>

so if your java is turned off on that page, or if your java is old and out of date, it might not recognize that class.

kinda odd that it just singles out that though.
 
  2010-12-30 01:09:56 AM
That's not Java, that's CSS.
 
  2010-12-30 07:18:55 AM
Since both IE and Firefox are affected, I would look for a proxy that does filtering (maybe for adblocking or as part of a security suite).

I have the missing tag problem when I turn third party image loading off or use a text browser, except for a few tags which must be hosted on a different server than the rest. This changed about four months ago, I think.
 
  2010-12-31 04:07:56 PM
Depending on your browser's definition of "third party", ALL our images are on a different domain (fark.net vs fark.com), and that's fairly common across other sites (see Facebook, Twitter, Amazon, eBay...)

One reason for that is it avoids sending cookies for every image request, saving upstream bandwidth and making things load a bit faster. The bigger reason is you can use a much simpler http server (nginx, lighttpd, or a stripped down threaded Apache config w/ no modules) or a CDN (Akamai etc) for it since there's no dynamic content to serve.
 
ZAZ [TotalFark]
  2010-12-31 04:45:49 PM
I think there used to be alt text and now there isn't, so it looked like a big change. If you put the topic name in invisible text where you now have a hard space text browsers would show it. I don't know if the design can be adapted for graphical browsers that reject third party images.

I used to work in the CDN field. I was always annoyed by the need for extra domain names. We need to delete the internet and build a new one with lessons learned.
 
  2010-12-31 07:23:28 PM
I haven't seen a good solution for alt text with css sprites yet.

Is there such a thing as a non-x86 PC these days? ARM is used for tiny computers, the other RISC processors for very expensive, usually rack mount computers. I have in my closet some relics of the era when you could get PC-like systems with RISC processors. The younger one is from the late 1990s. Below my standards. Sharp knees. (Really -- sharp edges on the case that I've cut myself on a few times.)

If not, who makes decent quality computers with AMD CPUs? I have an aversion to Intel. I don't care about bleeding edge gamer performance. I want something reliable that feels stronger than cardboard. ECC memory, not turn-off-parity-to-save-a-penny memory. I liked the old IBM built-like-a-tank systems. Low power would be nice; I don't need to use a 100 W processor to get twice the performance of a 1 W processor.

Last time I got a new PC-class computer was over 10 years ago and I built it from parts, so I'm not familiar with the options today.
 
  2011-01-02 12:46:41 PM
With Macs now being PC hardware, the quick answer to "is there a non-x86 PC these days" is no. There may still be a few PowerPC things floating around, but the days where you could get an Alpha ATX board or a PowerPC ATX board are long gone...

All of the companies selling RISC-based servers -- Oracle (Sparc), HP (PA-Risc), and IBM (PowerPC) -- all also sell x86 and x64 stuff now. HP is the last one still doing Itanium.

If you want a small MIPS-based system, take a wifi router and flash a custom version of Linux like DD-WRT onto it. You might be able to find PowerPC stuff in what's left of the Amiga community but it won't be too cost effective. If you want a low-power low-performance low-cost PC, get something Atom based, though none do ECC. (Some do x64 though...) If your application's just file serving then there's plenty of appliances for that, mostly Linux based, some x86, some MIPS, some ARM...

I've repeatedly found AMD to be less reliable than Intel overall. Intel's come a long way since their P4 days; they don't suck anymore. AMD did give us x64 though, which Intel then copied.

What's your application?
 
ZAZ [TotalFark]
  2011-01-02 02:44:11 PM
Basic application is my personal computer. My old Sun got sick last week and that reminded me how much I want a reliable computer. I mean build quality and long term reliability, not just avoiding CPU/chipset problems like Pentium fdiv or AMD's multiprocessor TLB bug.

Mild image processing, not render-for-weeks 3D stuff and not anything-for-another-fps 3D gaming. Integer programs with gigabyte+ working sets and odd memory access patterns (functional language). Simulation programs that generate 100+ MB log files as fast as the filesystem will allow (which does not mean ultrafast disks; I don't need all this stuff on the platter instantly). That last I can log into another machine to do. I'll run the programs locally if it's convenient.

Basic desktop stuff will run fast enough once I swat most of the UI out of the way. The Mac I've been using is a really odd mix of ultrafast and ultraslow, depending on how clever the user interface tries to be. DVDs play wonderfully. When a program decides to generate thumbnails for a couple dozen photos and it thrashes and spends minutes to forever. Opening a new tab in Safari is much slower than opening a new tab in Firefox on Linux because it gives me the "top sites" window instead of a blank window. And so on.

I want multiprocessor/multicore but any x86 will give me that these days.

Anti-Intel bias is personal feeling. I don't like rewarding the company. In any generation their processors may be better or worse on specs. Brute force engineering can make up for a lot.
 
  2011-01-02 03:53:09 PM
ZAZ: Basic application is my personal computer.

If I were you I would take a look at NewEgg or Tiger Direct. Prices all depend on bells and whistles these days. You can get a descent white box computer for under a couple of hundred. If you are not worried about OS then download your favorite flavor of Linux. Ubuntu probably has the closest interface to windows while Gentoo is for the command line gurus. If you do not mind used then you can pick up an off lease computer reasonably. Any AMD CPU that is rated at 2.0 MHZ and above should do what you want. The Phenoms are a bit pricey still tho. The big question is do you want a 64 bit processor or 32 bit. Oh, and most of the newer processors will support anywhere from 4GB of memory to 32GB with 8GB being the norm. Tiger direct has some 1GB ECC memory @25 bucks.

You can still build your own, the biggest issue would be what manufacturer of MB you want, and making sure the CPU slot matches the CPU you want to buy. I would get at least a 250W PS though. 1TB drives are reasonable now as well although it might be worth your while to get a SSD drive of 128GB or so. Loading your SSD drive with the OS and a partitioned TB drive for general storage, 4GB of memory and on board graphics, it should scream. With case and everything mentioned, probably around 400 to 500 maybe less if you can catch some sales.

/and if you already know all this then just ignore me, Just trying to help :)

I'm not really price sensitive, hence my mentioning build quality. I'm also not really a wizard with a screwdriver and I tend to accumulate static so my inclination is to buy preassembled. Like I said, I've built systems before. I have also danced, and believe me that was not a pretty sight. So buy if it's convenient, build if necessary.

Here is my thinking about computer price. I make a decent salary. I'm single. In winter I spend a lot of time using my computer -- more time than I spend driving my car. I can afford to buy one I like. I'm past the age when a man has to choose between giving up net access or eating ramen for the next month.

I have also been into and out of the phase when I bought Computer Shopper and said ooh want and one of those too and add on this and oh my god how much did I just spend? Prices are way down and performance at the low end is way up.
 
  2011-01-02 05:26:25 PM
If ECC's a requirement, get an X58-based desktop motherboard and put a Xeon E5620 on it. They're reliable enough that we use exactly that as webservers.
 
  2011-01-03 01:37:55 AM

  2011-01-03 08:02:15 AM
According to the list I just read, the top end of the line is actually lower power than the high end chips previously available. I'm surprised. I know Intel is "green" obsessed but being green takes third place behind the desire for the top benchmark numbers and the need to remain x86 compatible. I'm still not convinced that the typical user needs more than a 1 W CPU, or 1 W CPU+graphics combined.

As a fan of parallel computing, I like Google's concept of a thousand low power ARMs ("wafer scale integration"). I'm also told it will never work in practice.

Hey, all.

I'm doing a hard drive swap sometime in the next few days, and was wondering about software: I'm thinking Acronis True Image 2011.

Any opinions on this software? Or is there some (reliable) free stuff out there? I've been burned by freeware before, and it was a download from CNET, so I'm a little leery.

Thanks in advance.
 
  2011-01-07 12:47:54 PM
Looks like I may have just answered my own question; a version of the Acronis software is available on the Seagate site. Since I'm replacing with a Seagate drive, it looks like this may be the way to go.

I still welcome any advice.
