Hardware going belly up #hardware

My Samsung 305T plus started flickering in a weirdly regular pattern.

My first guess was that it was the graphics cards, as the pattern did not show when the cable was disconnected (and the monitor cycles through solid colours).

I needed to use the screen today, so I purchased a new cheap, silent Radeon graphics card, plugged it in, and ... no cigar, still flickering.

After searching some more, I realized that this is a common problem with this type of monitor. People have been fixing it by baking electronics, having the soldering refurbished, changing capacitors, and what have you.

So I decided to buy a new monitor. I went for a cheap 28" 4K monitor - it is smaller than the old monitor, but I could pick it up nearby and the price is like ¼th of a 32".

To drive it, I also needed a new graphics card, so I ended up buying a more expensive Radeon card along with the monitor. A minus is that it has fans - two. (I don't think I have bought two graphics cards on the same day before.)

Plugging in the new(est) graphics card didn't work - it seems like it isn't there at all.

Looking closer, I realized that it has a socket to plug a power cable into. A 6 pin PCI express power cable. Something my (nice, silent fanless) power supply does not provide.

So I can drive the monitor in 1920x1080 with the old(er) graphics card, until I get a molex to PCI express 6 pin cable. *sigh*

Update: Looking for a power cable like this... Jeez. You can order one that cost you 178 DKK, one that costs 123 DKK, one at 50 DKK, or you can go to Brinck Elektronik, where there is a queue on a Saturday afternoon, but the cable is in stock, and it costs 24 DKK, a whopping 2-7+x less.

First impression of 3840x2160@60 Hz on a 28" screen (which, by the way, just worked automatically with Debian unstable and a displayport cable): I need to adjust fontsizes and configure Firefox and Chromium to scale up (same as on the 3200x1800 screen on the laptop). A 32" would be nicer, but this will do.

Going to the moon

We choose to go to the moon not because it is easy, but because it is hard. Eating this bag of pinecones is also hard...

Sometimes xkcd is just spot on.

Neuromancer

I was lucky enough to get a Kindle Paperwhite for christmas. I was wondering what my first foray into buying a book in bit form only should be, when I came across this short article about the circumstances under which William Gibson wrote Neuromancer.

So I left the tab with that article open, and bought Neuromancer on my Kindle, from Amazon, at the grand prize of ~5.5$

I am quite impressed with the e-ink screen on the Kindle, it keeps looking very much like paper, rather than like a computer screen.

I was less impressed by the book, maybe because I did not take into account when it was written, as I read it. Or maybe because I have never read much science fiction. I have heard Neuromancer described as his best work, I guess that is very subjective, too.

And now I have finished the article as well. Yay!

Downloading tv shows from Danish Broadcasting Corporation (DR) #commandline

Some years ago I hacked together a script to download tv shows from DR, called drnuget - because I don't want to install Adobe's Flash plugin on my computer, and because Gnash does not work with dr.dk.

Alas, a while back, DR changed their website and drnuget stopped working. This, of course in blatant, direct violation of the Public Service contract. Oh well.

All is not lost, because another little hacky script, drplay at least allows you to watch shows, by digging up a URL and passing it on to vlc. Not that useful for downloading, though.

But now I've learned that youtube-dl (no longer that precisely named) can download programs from dr.dk, so we can once again download the programs we are forced to pay for - nice!

Update: I was very happy to see that Arch Linux' AUR had a package for my little script, but - alas - it turns out to be another little script, with the same name.

Tron #cinema #emacs

If you, like me, have just seen the movie Tron (1982) for the first time, this blog-post about the art of the sequel, Tron: Legacy (2010), will wet your appetite. The images look good, and... Emacs!

My Google Nexus 10 tablet was upgraded to Android 5.0.1. Now email doesn't work. Email never was essential anyway. Thanks Google! #fail

Jukebox and NFC/RFID #hardware #jukebox

I just ordered some small RFID stickers and a USB RFID reader/writer. Planning to put the stickers on albums, and to have the reader near the stereo, and adding a little code to play the album on the jukebox when waved nearby.

Let me know if you have done something like this.

Update: I got the PN533 usb stick today, and have hacked together a little script to handle it. So far I am simply using a UID to Album mapping, it would be nice to put the barcode, artist and album title into the tag!

And I need a USB extension cord, so the place you have to wave the album isn't very awkward to reach. And I need to put stickers on albums and fill in the mapping.

Too little time, too many links #biology #emacs #haskell #hst #perl #programming #work

Here is a bunch of apparently rare Hunter S. Thompson articles, that I ought to read: *HST – Rare Articles.

I have been trying to get myself together to learn Haskell for something like a decade now. When^WIf I get to be intermediate to advanced, I guess I should read What I Wish I Knew When Learning Haskell.

A REST framework for Haskell: Announcing rest - A Haskell REST framework. Cool! I think I may start with Scotty for just making a simple website. Growler I could not install on Debian unstable (base package too old).

I should set up Emacs for Haskell development properly.

I really ought to read up on Moose, roles and Composition over inheritance, but... isn't object oriented programming so last millenium? (It puts bread on the table, though, so maybe I shouldn't be putting it down quite so arrogantly.)

An article about "open source"/"free software" only on farming plants: Linux for Lettuce, which I was too lazy to read. See also: skeptical.

There is a cute introduction to Emacs lisp programming called "Casting SPELs in Emacs" - I got to page 5 before stalling. And the pages are short.

On the other hand, there is an Underhanded C Competition for avid C-programmers to compete in deceptiveness. My C is to rusty to try and compete. Or even read.

Advent calendars can be nice, this one is about free fonts, and in German. Perfect!
