GNU PDF project

I don't want to install wine and PDF XChange viewer just because it has some odd behaviour on linux. Scrolling does not work well at all. I wish the GNU PDF project would speed up and release the GNU Juggler

The code-named GNU Juggler will be a full-fledged PDF viewer and editor making use of the GNU PDF Library. Right now we are busy in the development of the library and the GNU Juggler is not even started.

I don't know why there isn't a decent PDF annotation program for linux yet. There just isn't. It's very odd. Evince 3.0 has note-taking but no highlighting and the developer told me he has no time to work on it anymore. Jarnal/Xournal/Mendeley etc. have fake highlighting where the annotation does not show up in other PDF readers and is not saved in the PDF file itself. Okular is fine but require installation of too many KDE components, is resource-hogging and kind of buggy as well.

Though linux has some really good PDF tools, sadly PDF annotation is not among them.

Terminator
changed keybindings for copy and paste (ctrl-c & ctrl-v)
checked use system fixed width font
Orage
made clock fonts bigger.
Removed stuff:

sudo aptitude purge chromium-browser chromium-browser-inspector firmware-ipw2x00 firmware-iwlwifi firmware-ralink fortunes-min gftp gftp-common gftp-gtk heybuddy gdm avahi-utils avahi-daemon fortune-cookie-db conky

Checked if google chrome is the default

sudo update-alternatives --config gnome-www-browser

tinypliny writes at 10:23:50 09/03/11 - Comment #64745: Where I comment out daemons? Pray tell! This is getting so interesting!

Yes, I was thinking of turning off bluetooth. I tried several times to pair my Nexus One to this laptop and do bluetooth transfers. For some reason it always fails so I guess I had better turn off something that doesn't work anyway.

uncutsaniflush writes at 10:06:32 09/03/11 - Comment #64742: (e:tinypliny) - Just in case you didn't know:

Launching daemons and services at start up can take a bit of time, so you should launch only the daemons you want to startup and comment out the rest.

Also, most BIOS have a quick start setting (that ignores some tests) at POST that can speed up the boot.

To significantly extend battery turn off your wi-fi and bluetooth on your laptop. Ironically enough, wi-fi (ards use more energy looking for networks than they do connected to a networks. I don't have bluetooth on anything, but I would assume the bluetooth cards would expend energy in the discovery mode.

On the Dell circa 2006 laptops we use at work, turning off the wi-fi nearly doubled the battery life.

I reckon I'm lucky I got a box from Zareason instead of System 76. But then again, I don't have your unique requirements and preferences. So who knows.

tinypliny writes at 09:28:04 09/03/11 - Comment #64739: Hmm... (e:Terry) too!?! Who knew.

tinypliny writes at 09:26:52 09/03/11 - Comment #64738: Hmm.. why am I so obsessed about getting rid of apps? Because they are clutter and pop up all over the place when I am searching for something else. I guess I have no valid space-related reason for getting rid of them but I just don't like things I don't use to be on the system. By that argument, there are a ton of components on there that I don't even know that I don't use... And that is why someday I want to take a shot at Linux from Scratch. But till then, I am honing my skills at "sudo apt-get purge"

Most of the other changes are aimed at making boot up quicker. I don't keep my laptop on all the time because it travels all the time between office and home and has a lamentable battery life of just under an hour even though it's only a few months old. I pretty much hate System76 because of so many reasons now.

Let me keep a watch on those errors when something strange happens.

paul writes at 11:54:47 09/02/11 - Comment #64737: I have to stop using their computers.

terry writes at 11:54:22 09/02/11 - Comment #64736: You have to really watch the errors while they are happening to know. The errors themselves are written by the developers so they could really say whatever that app's developer wants them to say. Same for OS X and windows. Looking at google that does seem to be about laptop hardware.

uncutsaniflush writes at 08:59:10 09/02/11 - Comment #64735: (e:paul) (e:tinypliny) - my theory that the changes made after the original install are the problem or a fresh install would not "solve" the problems.

I have a general question to tiny - why are you so obssessed with getting rid of apps? Are you trying to run r on a 1 gig hard drive? Are you really so short of space?

My guess is something(s) that tiny installs have unmet requirements that aren't covered the apt depends because the developer assumed that the box would already have it as part of a vanilla install.

I question getting rid gftp unless it is replaced with some other ftp app. For example some other app might call wget to do an ftp download. And wget will get confused and hilarity might ensue?

Why get rid of avahi? Why not just just change rc.d (or whatever the Crunchbang equiv is) so that that the avahi daemon doesn't start.

Why get rid of tty3 - tty6? In case of freezes or slow downs having another tty to killall apps or reboot can be very useful.

I'm not a big fall of gdm, I think slim is better; but starting x with a script can be a bit problematic.

Also, and this is based on personal experience. I would not mix using aptitude and apt-get. Use one or the other. I think that even though aptitude calls apt-get, apt-get has better dependecy handling.

I have to end by saying you are quite the Linux geek, (e:tinypliny)!! Well done!!!

tinypliny writes at 08:00:08 09/02/11 - Comment #64727: Should I be watching out for anything that starts with an "ERROR:" like this one:
Error (psparse-0537): Method parse/execution failed [\] (Node ffffffff8166d8d0), AE_ALREADY_EXISTS

How on earth will I know what it means?

tinypliny writes at 07:55:39 09/02/11 - Comment #64725: hahah yes, unless (e:matthew) has an secret obsession with linux that we didn't know about and suddenly decided to come out.

paul writes at 07:52:38 09/02/11 - Comment #64722: Oops that was me.

matthew writes at 07:52:10 09/02/11 - Comment #64721: I would start with /var/log/messages, its the main system log. You can read the end with tail. e.g. sudo tail -f -n 1000 /var/log/messages

That will display the last 1000 lines of the file and then continue to dump new lines to the terminal as they are added.

tinypliny writes at 06:43:41 09/02/11 - Comment #64719: Hmm.. I don't know what he runs. :::link::: Lemme see what I can find.

tinypliny writes at 06:41:33 09/02/11 - Comment #64718: What kind of logs should I be looking at?

paul writes at 06:21:09 09/02/11 - Comment #64717: I take it back none of those are too crazy. Either:
A. Your hardware sucks
OR
B. Crunchbang sucks
OR
C. Something with R.

Or a combo. What are you logs saying when the issues occur?

What type if computer does the crunchbang guy use.

Unsorted

I am at a weird point right now. Everything seems pretty unsorted in my life. I can't say that if I died tomorrow, I would be happy with the choices I made. That is not a nice place to be.

This needs to change, today and right now. I want to just take this weekend off the tracks and stop doing the same old things I do and the experience the same old panic. I want to start off anew.

I am promising myself that this weekend will be the most productive of any weekends thus far. And no other future weekends will end with panic ever more because they will all be better managed from now on.

Did you know that:

In 1752, the British Empire adopted the Gregorian calendar. In the British Empire that year, September 2 was immediately followed by September 14.

We will see how sorted I manage to be by September 14.

Arrgh, what's wrong now?!

Seriously, I can't seem to catch a break with my linux troubles. It's been hardly 14 days since my fresh install and things are already starting to act up with Crunchbang.

The stylus goes on insane object and text selecting sprees on its own and randomly refuses to be controlled. The bash history no longer takes orders from ~/.bashrc and never remembers even a line of history (even though I have set it to remember 10K lines). E4rat is installed and running, but applications have been slowing down.

I am SO sick of having to do fresh installs every fortnight. It borders on the illogical and for this reason alone windows XP seems rather appealing. Its rock solid and just as fast even after 1.5 years after a fresh install. Why OH WHY can't my favourite distro come even close to that kind of stability and consistency??

tinypliny writes at 04:43:04 09/02/11 - Comment #64714: Too late. I re-installed crunchbang and things are going okay now. If I face more problems in a fortnight, I will give scientific linux a whirl.

But yes, your point of having a distro for playing around and one for work makes sense. I am not sure I tweak so much though... In fact I am going to post my running installation notes here to see just what kind of tweaking is breaking my system. I don't think I am linux-y enough yet to make major changes, but who knows.

I really suspect that it is a hardware issue - mainly to do with the ATI card from hell that I have. I still maintain that System76 was a big mistake.

uncutsaniflush writes at 12:28:21 09/02/11 - Comment #64711: (e:paul) - that's what I think (e:tinypliny) is doing as well. I think your advice is very sound. I used to have two version of several distros on the same box - one for "production" and one that was a "sandbox" for lack of a better term to mess around with. I would try stuff on the sandbox and if worked eventually the production partition would get changed.

(e:tinypliny) - I like Fedora 15 so I'm hoping Fedora 16 will be even better. I like gnome 3 shell. I'm running Fedora 15 on my hex-core box and an asus eee netbook. I'm running Arch on a G3 ibook. I've been using PCLinuxos for about 7 years on the computer(s) that (e:leettee) uses. It is a fork of Mandrake/Mandriva. I consider PClinuxos to be a generalist distro. It is conservative and thus stable. I've had uptime of over 6 months using it. I still using it on her box because I really haven't had a reason to change. If it ain't broke don't fix it.

I really like Arch but I hate going through the install process. It's not hard or complicated but it can be time-consuming But I don't have the time for it these days. But Arch is great because one ends up with a customised distro that only has what one chooses to install.

I think that Linux Mint is a great generalist distro. It builds on your choice of Ubuntu or Debian.

Despite using Ubuntu Studio for over 6 months, I'm not a fan of Ubuntu. I prefer Fedora's automagic to Ubuntu's. I would recommend Linux Mint over Ubuntu.

I liked E-Live which was an E17 based debian distro; but the developer hasn't had a new release in over a year, so it is outdated.

Automagic installers like Fedora's anaconda are great until one wants to do something that isn't automagical. Yes, it is flexible enough to let you do customised installs but depending exactly what one wants to do, it isn't always intuitive or obvious.

paul writes at 10:23:07 09/02/11 - Comment #64710: I think you are either having an issue with your hardware being non standard or you are messing it up yourself by over configuration, unstable packages, and non stable distros, etc. I have Linux computers that have uptimes of 6 months to a year without even rebooting. And at that point the reboots are just for kernel changes.

I mean my parents could have easily assumed windows XP sucked and was broken until you fixed their computer by removing all of the problems they had.

I think you need to separate your experimental playground Linux space from your workspace using two partitions or harddrives so that when you continue to play and tweak you are not killing your productivity by having to reinstall.

That or use virtual machines for experimenting via virtual box.

You might also want to stick with a Linux that more people use. More people = more testers, more developers and bug fixes. Same with common hardware.

Have you tried scientific Linux? Its based on Red Hat Enterprise Linux which is extremely stable. It wont be as cutting edge as fedora Ubuntu, etc but it will be stable and it can definately run your r code.

tinypliny writes at 09:45:10 09/02/11 - Comment #64708: What kind of audio do you want to produce?

tinypliny writes at 09:44:40 09/02/11 - Comment #64707: 15 different distros?! What were your favourites? What are your favourites now?

tinypliny writes at 06:22:13 09/01/11 - Comment #64700: I can't work on Win XP. Linux is pretty essential to the software I run. So for good or bad I have to stick to it. I don't have a choice really. It's either decent performance with Linux or fester in slowness in XP...

uncutsaniflush writes at 10:25:01 08/31/11 - Comment #64691: If WinXP works so well, why are you looking for alternatives?

I would suspect that you have made more changes to Crunchbang in the last month than you did to WinXP in the last year or so.

Did you ever consider having more than one distro on your computer at the same time? You don't have to wipe out everything everytime you change your mind about what distro you use. Unless of course you have a very small hard drive.

I, personally, at one point, when I was a distro whore, had 15 different distros (including several different releases of the same distro) spread across 2 hard drives totalling 70 gigs.

Like (e:paul), I'm liking Fedora 15 with gnome shell a lot and use it daily on the new box. I'm still looking for the perfect audio production disto. Ubuntu Studio ain't it.

Good luck with Linux. But if doesn't work for you, there isn't any shame in going back to WinXP.

Peacock Shoe

I wish this shoe didn't have such hideous heels and were more of a flat Mary Jane instead. I would get it in an instant.

Well... maybe not this instant but most likely after a couple weak lopsided debates with my rational self on the complete insanity of shoe-hoarding. But those heels are the best safeguards against any impulse buying.

Hurricane Irene.

This massive hurricane is headed directly to NYC, Long Island and New Jersey. I am more than a bit worried. My brother is in zone A - categorized as the most flood and storm-prone in the city and likely faces evacuation this weekend.

Baruch College 155 E. 24th Street, HS of Graphic Comm. 439 W. 49th Street and John Jay College 445 W. 59th Street are the nearest evacuation centers. His building has already sent out an emergency preparedness notice.

All this is making me really nervous. I am desperately hoping that this hurricane changes direction and is somehow deflected well away from the whole NYC region. :(

It's not lent but...

A chain of rants in (e:metalpeter,55007) make me want to throw down this self-improvement challenge.

I am ready to
a) give up salt for however long it takes
b) start doing push-ups all over again everyday for however long it takes

if someone else wants to give up something or take up something with me and be accountable for that here. It has to be something that is causing you harm or is damaging your life or is negatively influencing your life to some extent.

Too much salt and not enough muscle definitely are negative influences on mine.

Who is up for this little last-quarter goal-setting?

Definitely an earthquake

I felt it and I thought, wow the wind must really be picking up in Buffalo. Guess it was really an earthquake and not just the building showing its age and resonating with the wind.

LOL@ this comment on the story:

Soon to be former Buffalo schools superintendent James Willians was seen jumping up & down in a temper tantrum b/c he could not get anyone to help pack his belongings...

Seriously, do people stalk the Buffalo news site just to post stuff like this? Hahah
