nice should-be-easy video on howto compile stuff on ubu.

a few tips:

1. apt-cache search ncurses dev

cause what you want if you compile stuff are the development headers of libraries.

in a current ubu lts its libncursesw5-dev (which is 64bit btw...)

im not going deeper into ncurses at this time, youve either already looked it up or never needed it again;-)

2. read the readme/install files in the source tree and/or check the developers website, much better than stackoverflow, because so might be good, but it has alot of bogus tips as well.

a few optional tips on building stuff on ubuntu:

1. check the ubuntu wiki, they also have tons of tips for devs there.
2. in order to compile or build anything, you need the base devtools/helpers installed, usually what i do on the compiling box is:

apt-get install devscripts gcc gpp automake autoconf libncurses-dev pkg-config ccache

3. use make flags, in example to let all your cpus work for you in compiling your sourcecode i do a:

make -j4

on my dual core machine.

had a look at a web browser that finally integrates very well with my tmux vim i3wm setup, its called uzbl, and if you are used to vim, youre gonna love it, i wouldnt call it production environment ready yet, but its a very nice, lean, easy to configure and fast web browser.

running wildfox, compile was as smooth as i havent had it in a while, thing looks really neat and its fast, only prob i came across is, that i cannot copy & paste data.

anyone else here running WildFox? (https://github.com/MayaPosch/WildFox) would love to know if im the only one having the problem.

ps: some data -> base OS xubuntu latest, base QT 5.1.0 betasomething (downloaded today...)

is the html5 video tag dead?

after loosing mp4 support, and ogv being removed by some too, while others dont even have implemented it yet, and theres no actual way to have a low quality stream going directly to it without 3rd party software, is the web standard tag dead before it even came up?

ive been playing the past few weeks with the video tag, and even with drop in flash solutions, multimedia content on the web is still a "include as many things as you can and maybe itll work for 80% of the audience" thing.

just have a short look on the current support table:

Hello Matthew

concerning your video "Mythbbusting Linux".

1. linux has viruses as windows does:

very true, but the viruses you found there clearly had the ending .exe, so they wouldnt ever affect your linux system if you wouldnt specifically run them in a windows vm guest or with wine, and even then, they wont affect the root system. the program you downloaded from sourceforge... had so called spyware attached, its what happens on sourceforge nowadays from time time time, since they got bought up by some shady company a few years back.

there is hundred of boxes on the internet which are infected by rootkits, those are infected because peoples proactive scanned for old server software and infected those boxes, thats where your av wouldve been placed correctly, however, nice that you did spend money on that for your desktop pc, keep on helping sophos;-)

2. defrag was there, ages ago, with ext2, if you bother reading the file system docs of the different partition formats... youll find out, that it really matters what you are using, sure theres fragmentation, but it only appears if your partition runs full of data before the drive can journal correctly, which once again only is a problem if some mistake happens in your software, and you dont have a.) disk quota or b.) "defaults" as an fstab option in place, cause defaults writes journals so often, that the chance of data overrun thus dangerous fragmentation is very low. so, its good that this program is there, but you wont ever touch if if stuff doesnt go wrong, especially not as often as every week.

more truths on fs ext4 (todays standard on most distributions):

http://kernelnewbies.org/Ext4

3. machines running forever? up until a few kernel versions ago, i wouldnt have suggested never to reboot your system, and thats what the other guy was talking about, restarting a program/service is a 2 seconds action, really, rebooting your machine though, depending on the trunk of installed software or real life dependencies (imagine a board computer of a jet doing reboot mid-flight...) can be cumbersome. have a look at a new feature of kernel 4.x http://www.zdnet.com/article/kernelcare-new-no-reboot-linux-patching-system/

4. you are wrong, the uid you see there as the blockid (bkid) of your hard drive, thats what grub refers to, so if you take really the drive out and put the drive into another system, itll boot.

i realize you at least know what an fstab is, good, so my words wont get through without some thinking on your side...

eventhough you know fstab, you dont know?

however, change the uuid (blkid) to /dev/sdX... and itll work just fine. cause the old system is still there, and we are upward compatible, unlike other stuff... 

the only thing you cannot expect to boot: an arm kernel on a x86, an x64 kernel on an x86 or any of these on an apple 9 or an uefi drive in a non uefi pc (your problem case) etc...

please keep on learning things, dont call yourself expert without reading the correct manuals first and stop flooding us with myths, that are at least partly wrong, same goes for alot of the things ive watched over the years on youtube and/or the web.

im not gonna bash on you, you are on your path to learn stuff. but please,
check your facts.

right now you are giving basic misinformation about a system you are in fact know very little about and you are just learning about. give it a few years, and maybe youll get into the position.

Havin' a great late night, after upgrading my mainboxes to debian latest stable, now revisiting some 6 years old code (by choice):

Things that changed inbetween: i do way more error handling nowadays than i did back then.
