General Linux Chat and Small Questions v. I broke my Arch Install - Hardware & Software

My boss asked me to fix an apache tomcat server because the application hosted on it wasn't working properly. All I can say is that jesus fucking christ it's almost impossible to debug this shit.

Anyone have a better PDF reader? Currently using "Document Viewer" since it came with the install, but I notice that it is rather sluggish.

[QUOTE=diwako;43783260]Anyone have a better PDF reader? Currently using "Document Viewer" since it came with the install, but I notice that it is rather sluggish.[/QUOTE] Evince is a nice one.

[QUOTE=Darkwater124;43783381]Evince is a nice one.[/QUOTE] I think its Evince that he is already using. [QUOTE=PredGD;43778262]yeah of course, but that's the part that annoys me. I want to use linux 24/7, and can't be bothered to reboot the computer everytime I need to use some windows software.[/QUOTE] What about virtualization? Virtualbox has an "Seemless Mode" that makes Windows programs work great together with the Linux desktop.

i just use foxit because it has the best automatic watermark removal

Can't Chromium/Chrome handle PDFs?

Somehow I don't think he wants to open a fully fledged web browser to view a pdf

Use mupdf It's very lightweight

Currently using "Document Viewer" since it came with the install, but I notice that it is rather sluggish.[/QUOTE] I've never seen a fast PDF reader on any OS, for some reason. Adobe Reader is slow as shit, Okular is laggy, Evince is slooooooow...Only PDF viewer that's ever performed good in my experience was the one built-in to Windows 8(.1?) :v: Well I guess the ones built-in to Chrome/Chromium are decent, too...

how would I go about making a bootable windows 8.1 USB stick using my .iso image?

[QUOTE=MasterFen006;43784025]Can't Chromium/Chrome handle PDFs?[/QUOTE] Google Chrome's PDF viewer is not part of the open source Chromium. You can install it as a plugin, though.

I use Firefox or Chrome as my default PDF reader. Loads faster and is more stable than Adobe.

Day 3 of the Apache Tomcat server debugging. Coffee helps me to not think about burning down the server room. I have yet to find the rumored config that contains the mysql configuration for the application. The tomcat server logs are not helping and only seem to taunt me with their endless stream of mysql connector exception stacktraces. The coffee machines on all the other floors broke down so there is a line at the one down here now. I fear that it might run out soon so I'm preparing to burn down the server room anyways. My boss keeps asking me if I'm not going insane and I just look at him, smile and say "Yea sure it'll be done by the end of the day". But seriously fuck Apache Tomcat. [editline]asdf[/editline] Fixed it! (few posts down)

[editline]5th February 2014[/editline] Okay you have to be shitting me. What they do is make a dir in /etc and put ONE fucking config file in there. The documentation telling where the file was was tucked away in their really strange wiki. It seems like I don't have to burn down the server room anymore

AFAIK Apache Tomcat's appliances are in a .war file. The war file is like a jar, but for web appliances or some stuff. The DB info may have been hardcoded somewhere in the source code. (If so, the person should get fired) (Or a config file, embedded into the war file)

I fixed it now tho it was a really obscure config file that was commented with stuff like todo etc.

just imagine the NSA cracking that password only to find a minecraft server

I got a 50 character password on my main email account. Just to be safe [editline]5th February 2014[/editline] I would have gone bigger, but the mail service only supports 50 character passwords. Also, My private "cloud" containing all my important services (proxy, owncloud, mediawiki, gitlab, etc...) is secured with a 8192 bit RSA certificate, so I might seem a bit paranoid.

I have a question about which distro to use for my purpose. I have a friend on WinXP, he has an AMD XP 2500 Barton and 1.5gb ram. He uses this computer for office work and cruising online mostly, listening to music too. He isn't interested in buying Win7/8 for this computer. My idea is to set him up with Linux, and show him Libreoffice. I have a 4gb USB stick I'd like to use instead of a CD/DVD. I've made a bootable stick with Pendrive and Mint 16. Now I know I need to use that 'persistent' option to make and keep changes to my Linus drive but how large? If I have 3.xgb free on the USB stick do I use all of it for the persistent thing? Or do I need to reserve some of that drive for other things. It's formatted for FAT32 btw. Or is Mint too big of a distro to use for this purpose. I'd like to show him how Linux can play music and video, so I figured Mint was the way to go. I'm willing to go with another flavor and add the parts I need if that'll work better.
