It is true that you can install software in a live session of Ubuntu, when booting from a USB stick (called a Live CD). Where it stores it depends on which kind of USB stick you have made (persistent or non-persistent, as you mention yourself). To provide a complete answer, I will mention both options below. If the standard, non-persistent session is used, ...

You may need to switch the cards. Right now you have the 1GB cards on bank0 and bank2, with the 2GB cards on bank1 and bank3. Check with your manufacturer. According to http://h20331.www2.hp.com/Hpsub/downloads/Mini_WP_Z800_memory.pdf and http://superuser.com/a/107753/317065 You may need to put the two 2GB cards on bank0 and bank2 instead. ...

I don't know why it doesn't show when you run the command sudo dmidecode --type memory. However, a quick google search of the part number M378A1G43DB0-CPB shows it is DDR4. Near the end of page 6 of the following document, the product is listed under 4.7 288Pin DDR4 Non ECC UDIMM webcache.googleusercontent.com/search?q=cache:www.samsung.com

I'm still not sure what the original issue was, but when I rebooting using a "recovery kernel", that seemed to get around the issue, and now my machine boots normally.

TL;DR Your memory module is broken. Sorry to be the harbinger of bad news. (harbinger – Thx @Fabby for the nice word) Explanation Tst – shows which test has failed Pass – Test 4 has one pass Failing Address – shows exactly which part of the memory has errors. Good and Bad – show the data that was written and what was retrieved respectively. Both ...

I was experiencing freezing using 15.04. I tried the additional drivers and it did not fix. Then booted up after a freeze, went straight into the software center and simply installed all the available Nvidia software through the software center. After that, great performance everything worked nicely. Set server preference to performance, not high quality.

Easy: run your program as many times as you have cores... I do the same to transcode video in multiple formats: not all video-encoders are multi-core/multi-CPU-aware, so I run a video-encore for one resolution on one core and the other one (with different command-line parameters) on another core. Low-quality reviewers: some complex problems have ...

According to this: https://www.biostars.org/p/44231/ it sounds like clustalx will only the one core, and you need to use clustal omega or mafft.

No, it just dumps a load of stuff (slab objects and pagecache) from the system cache. If your system is out of memory (and I mean: deep into swap usage, nothing free, hard disk churning) then yes, this might help... But not as much as: Buying more RAM, it isn't expensive or hard to fit. Closing something that's using lots of memory (or tabs from a ...

No, see How do I clean or disable the memory cache? for an indepth answer. Cache is there to be used and to speed things up. So Linux makes full use of caching. If you do this it will takes seconds for the cache to be filled up again. Adding hardware to your system would be more efficient (depending on what triggered your question it might be memory or ...

You can also write command as: echo 3 > /proc/sys/vm/drop_caches The above command will free pagecache, dentries and inodes. And sudo sync is used to to make sure all cached objects are freed as dirty objects are not free-able and the echo operation is non-destructive.

use kill -SIGSTOP $(pgrep process_name) to suspend a process and kill -SIGCONT $(pgrep process_name) to resume it. In terminal the shorthand would be: Ctrl+Z to suspend and fg to bring it back into forground, bg to make it continue in background.

That's because in the first line of free the memory is calculated considering (adding) the amount of memory used for caching and buffering. "System Monitor" shows memory usage without considering the amount of memory cached and buffered. Check out the line -/+ buffers/cache: 1.1G 783M of free, this is the same to what "System Monitor" is ...

From the (few) sources available (such as this one at Engadget: http://www.engadget.com/products/acer/aspire/one/zg5/specs/), it would seem that the RAM controller chip in your netbook is capable of using only 2 RAM slots, each with up to 1 GBytes. Since you already have 512 MBytes in one of the slots (soldered to the motherboard), following this reasoning ...

If you really need to save these files, you will have to move (i.e copy, and delete originals) them to a different media. Thy appear too large to save on a DVD, so either a tape drive or a large memory stick. OTOH the files look by their names like installation file, including sources. Why save them? Rather delete them and find a way to backup your currens ...

What do you know! I got it to work! For whatever reason the computer won't work with un-equal capacities of RAM. So, I just got another 4GB stick and all is well.

Both seem to be Hynix memory chips but on the Hynix web site, I can only find the technical specifications of the HMT351S6CFR8C and not the HMT125S6DFR8C, so I cannot compare tech specs to see whether they even can work together there... However, I found a product catalog on the Hynix web site and that confirms my suspicion: the HMT351S6CFR8C-H9 has a ...
