Computing aside Jamie_Wizard, you still have your Christmas tree up!!!! This is shocking!!!! We're practically mid January now!!!


Hahaha the photo was from the other day, but I didn't get a chance to actually post the reply!! That said, I was always told it was the 6th to get rid of the tree, and feel a bit weird for still having the tree. Just been too busy to take it down (having to pack everything away), lol

So, to sum up. I absolutely love Linux (it's necessary for my research and computation work), but I hate it for Microsoft Office (it can be run using Wine) or LibreOffice. It's OK for Latex editing in Texmaker, but prefer Mac or Windows for that. It's alright for viewing PDFs, but again my mac/windows laptops are just nicer for this.

Eng, that's the funniest operating system analogy I've heard, it made me laugh out loud!

Tudor, you're most welcome.

Nead, VMs (virtual machines) are a useful tool, especially when running them to provide compatibility for software or servers (although this is being superseded by the containerisation tools such as Docker and Singularity). They are, however, often quite slow when it comes to graphical user interfaces, also requiring a lot of RAM and CPU resources.

This is my cluster, now in my living room. They each run Ubuntu 16.04-LTS, have 6 cores (12 hyperthreaded cores), and 32GB RAM each. But the badass part is I managed to get it working with Infiniband and I'm getting ~8 Gbit/sec (8x faster bandwidth than Gigabit ethernet)...Computation is done with Openlava (Opensource IBM LSF) and Apache Spark (Hadoop platform).

I usually use it via my MacBook Air, my desk (on the left), or sometimes via my windows laptop.

Quote From Tudor_Queen:
A final consideration - I'm considering Lenovo, Dell, or HP (and in that order) in case that is relevant to this question.


They should all work. When I ordered my Dell Worksation, I was able to choose to have it pre-installed with Ubuntu. Installation would never pose a problem for me (as I maintain Linux servers), but I was pleasantly surprised at this. So, perhaps you could order directly from Dell. Alternatively, you can download Ubuntu 18 - make sure you go for the LTS version (Long Term Support), which means it's supported for many years to come. That way you could pick up a cheaper laptop from Curry's/ PC World and then install it yourself, electing to wipe windows. In my experience, Dual boot, where Ubuntu offers to install alongside windows, is quite unreliable. If something goes wrong, you'll need a technical person to help fix it and may not be able to access your Windows installation even if it's present. So I'd avoid using that option, and install Ubuntu as the sole operating system.

Best wishes,
Jamie

Quote From Tudor_Queen:
Beyond that I guess I mainly use my laptop for: doing stats on SPSS and R, using a few bits of open/free software specific to my field (such as CLAN which is part of the CHILDES project - which I've just checked to see that it has a "Unix" version available to download - I am hoping this means it would be compatible with Linux), Skype, viewing photos, and, importantly, reading lots of PDFs (currently I use Adobe to do this). Would I be able to transition to Linux fairly easily and do these things with the same ease as in Windows?


I'm not familiar with CLAN or CHILDES, but on quick inspection of their website, it appears their "UNIX" version (actually Unix is pretty dead, and Linux has taken over - so I guess they are referring to Linux) only supports command-line (i.e. you run the program by typing in commands) and doesn't have a visual interface. This should be straightforward for you to pick up.

Quote From Tudor_Queen:
A second question relates to installation. I will probably buy a new laptop soon with Windows 10 preinstalled. Do I need to look out for any particular specifications, or will I be able to download Linux on pretty much any modern run-of-the-mill laptop?


Linux will work on pretty much most machines and will do the best job of making use of resources optimally. However, a potential issue could be support for Graphics chipset (the graphics circuitry on the machine). Specifically, finding driver software to get the most out of some graphics cards could mean having to go to the effort of installing propriety drivers (instead of using existing ones). If the graphics chipset is common, then this is less likely to be an issue.

Hi Tudor,

Hope the following helps...

Quote From Tudor_Queen:
I'm considering switching from Windows (can't stand the interface on more recent versions and the lack of user control over this and other basic things) to Linux. I've been casually considering it years but getting close to taking the plunge (forced by external factors such as Windows 10 now being the only Windows operating system available on new laptops). I wondered if anyone here uses Linux? If so, I have a few questions for you!


I use Linux at my workplace workstation, my workstations and servers at home (alongside Windows and Mac OSX). It's a must for Computer Science, Computational Biology/Chemistry. The only issue I had at work, where we use Skype for Business, was that the Business version wasn't available for Linux/Ubuntu.

I personally use two laptops. My personal laptop is a Windows 10 Professional laptop with Linux Ubuntu Subsytem for windows installed - it can be installed as an option at any time. This allows me to use Linux Commands on my Windows laptop which has been exceptionally helpful duing my PhD. Though typicallly I'd log in remotely to a powerful cluster of machines in my spare computer room (at my mum's house) or the universities cluster. My present work laptop is Mac OS X. The main thing is it's light to carry and OS X has a Linux core, allowing me to also use Linux commands.


Quote From Tudor_Queen:
First of all, is it fairly easy to get used to it and easy to do simple things that you might do on Windows (browsing, Youtube, etc)? ....


I know of a few non-technical people who use Linux (Ubuntu) on their laptops without any problems and they seem quite happy with it. You're right, Libre Office is compatible, but in my experience I never enjoyed it as it corrupted my documents and formatting was often a bit off.

Hi all,

Sorry for the slow response, I've been in Prague.

I had good times being a member of the Tennis, Photography and Cyber-security societies of my uni during my PhD. I think now I'd probably only join one or two sports societies as the others are probably too "studenty" lol. I did a fair bit of teaching my PhD my students were always inviting me to parties and trying to get me drunk!

I did find out that Imperial college union offers an associate membership which one pays for monthly. It's available to staff and other non university members, so if I have the time I'll get one of those.

Bewildered, you raise an important point, which I'll keep in mind.

Thanks Tudor for your good wishes, I really appreciate it :-) I do hope you are enjoying the Christmas vacation. When you say "isn't one of the perks of academia to sort of be your own boss when it comes to that sort of thing - as long as the work gets done?" that's my sentiment exactly, and one of the reasons I took a post-doc and one of the positives of working in academia.

How's everyone?

Merry Christmas,
Jamie

Hi all,

I'm excited to have secured a Post-doc in Imperial starting in about a months time :-) . I found that Imperial have a college union, and I wondered if it's ok for Post-docs to join? I would like to join their Tennis society and perhaps take up martial arts again.

I am also wondering whether it's OK or usually accepted for post-docs to come in and leave after rush hour as I'll be commuting from Greater london and the rush hour is usually pretty hectic. I did this during my PhD for which I had to travel quite a distance in to uni, which was cut by half the time avoiding rush hour. Same question for some days working from home - I've been able to work from home 1-2 days from my current job in a large research institute.

Of course I'd have these discussions with my new PI, but just wondered what was the norm/acceptable. I want to be as productive as possible, which i find doesn't always fit 9-5 (aside from when I will have to be in early to give a lecture/workshop).

Cheers,
Jamie

rcty, it's not such a bad start. At the very least you have a post-doc of sorts and employment. If you want a different post-doc, I'd start looking now, as they tend to be quite specific and also can be competitive. Given you have finished your PhD, I think if you can demonstrate to a prospective post-doc PI that your research, skills and knowledge from your PhD would further their research you shouldn't have any problem securing another post-doc.

I'm very sorry for your loss. I too lost a parent (my father) relatively suddenly when I was halfway through my PhD. It was tough. I decided to keep my mind busy by being active and presented at a conference 2 weeks later and another a month later, and continued with sports. I did, however, make sure that whenever I felt feelings of grief I'd not block them and I think that helped a lot. If I had decided I needed time away I wouldn't have hesitated to organise this with my supervisor. In my case, I felt I was enjoying the progress with my PhD, my father would have wanted me to carry on and so I did and dedicated my Thesis to him.

Also, sorry to hear about your situation with your supervisors. I would follow the advice eng has provided and try and work out a way forwards, particularly as eng says, by setting achievable milestones that you all are satisfied with, failing that then it seems the only choice would be to move on. Best of luck.

You could just be exhausted/drained from it all. How about a vacation and more hiking!?

I totally agree with pm133, I'd ignore nonsense such as it being frowned upon to do a post-doc with your PhD supervisor. Of course, it could be good to experience working with another in a different institute, but also that could not go to plan. If you work well with your supervisor then continue. it looks promising that you will be working on a different project.

I would spend the first part of any vacation totally switched off, and then when you feel ready, start to think a bit about your options in academia or elsewhere.

All the best,
J

100 is a bit steep. I paid about 65-70 for 3 copies, also an official copy was submitted electronically.

In our department, we all had to pay for our Thesis printing and binding.

Thanks Tudor. Yes, my friend is OK, thank you for asking. I was lucky that i was confident in my cardiovascular knowledge from my Pharmacy/Chemistry degree, had it been a burns injury I'd have forgotten everything I learned when I did the 1st aid training in 2011.
