Comment on LU Decomposition in C (and under CUDA) by Bolster

Bolster — Fri, 25 Nov 2011 12:27:26 +0000

AFAI Can remember, the point of this section is just a simple vector transposition; Q containing the mapping of x->x (in this case), so for the final matrix x, initial matrix xi, and transposition matrix Q, x[i] should contain the value of xi[where Q[i] points to ].

May be wrong, but its been a long day already! And it gave correct results the last time I tested it.

hi, I think the last step to solve x=Qz should be x[q[i]]=xtmp[i];

Comment on Why Belfast Needs a Hackerspace by The Plan: Confessions « QUESTS

The Plan: Confessions « QUESTS — Mon, 24 Oct 2011 12:58:10 +0000

[...] As for long-term plans for development, I would like to see QUESTS become a stable society with interesting events with active membership, and eventually build the community both inside and outside of QUB, with an aim to acquiring a space in Belfast where like-minded people can fiddle, work, and learn together, and hopefully spin out some really innovative start-ups. (For more rants on this idea, see my blog). [...]

Hi,

thanks for the idea. I have installed the sendemail software and after the tweaks mentioned by ubuntudroid, it reallyworked. So thanks to you both.

Anyway I decided to check WHY it is working. It turns out that this feature is actually already documented by Amazon:

Option to Convert PDF Files to Kindle Format
If you prefer to have your personal PDF documents converted to the Kindle format so you can take advantage of Kindle functionality such as variable font size, annotation, Text-to-Speech, etc., type “Convert” in the subject of the e-mail when you submit your personal document to your @kindle.com address.
cited from here: http://www.amazon.com/gp/help/customer/display.html?nodeId=200375630.

So to wrap it up: you do not need the complicated setup – neither additionally installed software, nor your password in clear text on the file system. It is enough to just send a mail with attached PDF and subject “Convert”. I already tested it and it works like a charm Hope this helps someone else.

Best regards,
Tanya

Comment on Replace Unity with AWN and Gnome-Do by OttifantSir

OttifantSir — Fri, 23 Sep 2011 21:05:56 +0000

Thanks for pointing out Tilda to me. It seems like a great program, and one I hadn’t tried before.

It’s also good to see someone else who seems to understand the concept of minimalism, which I feel Unity is not. It’s neither unobtrusive or user-friendly in my opinion. AWN is great, and I’ve used it myself for a very long time. That is, until I finally understood the power of DO a few weeks ago. Who knew the Tab-key could be so useful? (That’s really what’s missing from EVERY guide on DO I’ve seen: Write something, use Tab if you don’t like the action presented).

After trying to get it for a very long time, I finally have my perfect setup: After login you see a stunning picture, nothing else. With DO I have removed AWN from startup, replaced a very few of the functionalities of a panel or Unity with Screenlets (InfoPanel is a great one!), otherwise I have assigned everything to keybindings. Still have AWN for when I have visitors over. Can hardly expect them to memorize 100+ keybindings to use a computer for a little while;-P

I don’t know if my ONLY problem with removing Unity is the packages I removed (EVERYTHING saying unity) or my nVidia graphics, but I had a problem of showing videos in fullscreen with VLC where the titlebar wouldn’t render, instead showing the window behind VLC. This has been solved by turning off Window Decorations in CompizConfig Settings Manager. I now love my Ubuntu so much! Earlier I had a problem with cramps in my back and neck, pain in my mouse-arm and other common problems to computer users. Now I have gotten rid of all of them, and I’ve got a BEAUTIFUL and QUICK system! Only way I now know of that can make my system quicker (apart from an expensive upgrade of EVERY hardware component) is telepathic control.

Comment on Customised User Directories in Ubuntu by Anthony

Anthony — Sun, 18 Sep 2011 22:59:59 +0000

This is a pretty cool idea, at first I used it to sync my desktop(!), documents, and pictures between my laptop and desktop. One thing that I didn’t like was that it left the Home folder empty of all those folders (along with the Nautilus sidebar). What I instead ended up doing is using the original user-dirs.dirs file settings and deleting the folders in /home/ and creating soft symbolic links to take you to the Dropbox folders (ex. ‘ln -s ~/Dropbox/Desktop/ ~/Desktop’). This way I still have my /home/ folder icons but am able to sync my folders with Dropbox!

Comment on Intel 4965: Poor wireless performance under Ubuntu by GD Post

GD Post — Tue, 16 Aug 2011 03:06:18 +0000

I have been to nearly every site out there for this issue. Just so everyone knows my issue, here it is:

Desktop connecting via wireless card using ubuntu 10.10. Uninstalled and purged network manager completely. Restarted wicd. Still got the BAD PASSWORD message. Tried updating the 10.10 kernel. No good. Issued following command:

sudo apt-get install linux-backports-module-wireless-maverick-generic

Restarted. A little slow, but it finally works.

THANKS A METRIC TON!

Thanks for the coreboot post. It is great to see new developers getting involved with coreboot. This board would be a great addition. Keep us posted!

Comment on LU Decomposition in C (and under CUDA) by Bolster

Nope, fabs (and fabsf) have been in the device API since at least CUDA 2.0

As in all things CUDA related, consult the guide

This is a Linux/Mac solution, I am not clear on the Windows side of whether this would work, as it was discovered by accident, and we don’t know what exactly is ‘triggering’ the conversion behaviour. Its been suggested that simply having ‘Convert’ as the subject would work. Experiment and report back!

Of course, if all else fails you could look at Cygwin or Ubuntu. (Google is your friend)

Hi,
how is that in your gpu code you use fabs function,
isn’t that a host call ?

Could you explain more exactly what you did? (Because I’m new at this stuff and I´d really like my kindle to do that.) So could you do something like step by step and what programs are needed (hope they’re free, so that they can be downloaded).

Thanks in advance,

Comment on Replace Unity with AWN and Gnome-Do by Bolster

Bolster — Sun, 10 Jul 2011 12:11:19 +0000

I’m glad you found it useful. I just can’t stand Unity at the minute; its a really nice idea, but its fundamentally broken on so many levels, and the Ubuntu dev community is fracturing around the difference between ‘forced usability’ and allowing for the kind of deep customisation that we’re used to.

Comment on Replace Unity with AWN and Gnome-Do by Andrew

Andrew — Sat, 09 Jul 2011 01:33:01 +0000

Thanks for the post. I was using gnome-do on a Xubuntu install and preferred it to unity, so this is exactly what I looking for to “fix” my Ubuntu install. I’ve only been using it for about half an hour so far, but I’m pretty sure it’ll stick.

Thanks for the second-eyes; the difficulty with writing blog posts one a different machine to what I usually work on is the lack of `history`and my faulty memory!

You are correct in both points, but I didn’t know about the subject-line/convert point.

Thanks again.

Ah, and I forgot to mention: I also had to install two additional packages to get this to work, namely libnet-ssleay-perl and libio-socket-ssl-perl which provide the necessary TLS support.
