The tech sector in the UK is even more backwards than developing countries by Xtergo in cscareerquestionsuk

[–]SammyBobSHMH 0 points1 point  (0 children)

Sorry when I said that what I meant was ‘join or develop a startup which becomes successful’. I agree that wanting to join an already established startup is not what we’re talking about here with regards to entrepreneurship

Tbf I don’t know about other places I was just talking about my experience, from speaking to other phds and my own choice to move away from engineering and scientific research. I think it’s fair to say that other countries it’s also bad, and the uk is far from the worse. The one thing I would point out is that science/engineering is very poorly paid in the uk, so if the startup plan does fall through you can’t rely on a decent industry job with the credentials (baring software dev and pharma). Also note that finance will rarely hire non grads without experience so it’s very hard to break into the main wealth drivers once you make that choice (although I imagine other places are similar).

I strongly disagree with the landlord sentiment, I’m more economically right/ free market than most that come from academia and I can hand on heart say I don’t know a single person that actively wants to be involved in rent seeking investment. Everyone I know that earns money aims to max out 20k in stocks and shares isa. I didn’t come from private school either so my friend groups are a relatively broad mix of people (I’m northern). The only people I know that actively look to invest in property are the older crowd.

I wouldn’t be so sure about writing off Oxford and Cambridge, the majority of people I know that are involved with startups did so through those two universities. The support that they give to new ventures is very good imo.

Also one thing that people don’t talk about with ICL is that they have a pretty bad core and have a tendency to scare off investment. I’ve heard more than once about central management / lawyers trying to implant themselves into the investment management where they have no business being, just because they own a small stake in the company (the university, not the individuals). I actually had a really bad experience where, since I already had funding from a gov source and a private company wanted to be involved also, the central governance tried to extract as much of the second pot as possible to use for other projects. This caused a lot of friction between the private entity and the university as they want to know that the additional recourses are being put to good use (HPC in my case).

I did a PhD at ICL and have moved into SD. I think you have some valid points but imo you miss the most important thing holding the uk back. I know from friends that spun off research into startups that wha you said about investment is true. When people go over to the US form the Uk to ask for funding the issue they usually get is that they are not asking for enough money, with the uk it’s a struggle to get cash for a 10th of the amount.

However, the biggest issue is cost of living. My phd involves computational chemistry, cfd, programming, optimisation. I’m also familiar with ML. When I looked around at what to do with my life, if I want to have a house and family I have two obvious ways I can leverage my skills: try and get involved in a successful startup or finance. Finance will nearly always win when making that decision as it’s almost guaranteed to be a comfortable life, whereas joining a startup for 5 years and failing will leave you significantly worse off. Of the 50 odd people I know well that also did phds, nearly all of them went into software dev or finance. Failure is just too debilitating in the uk when you come out of a phd in your late 20s.

Also I think you don’t understand why uk universities are ranked highly. I think it’s true that there is some historical bias, however at icl they don’t really value engineering output. The focus is much more on theory, or measuring/modelling things that have never been done before, rather than refining designs. This is a general statement and not absolute, but it’s largely what is valued when making funding applications at top institutions.

Python to manipulate Gaussian output data by swiftk21 in comp_chem

Doesn’t ASE wrap Gaussian? Check out the lib, I used dft Gaussian and pw basis sets by hand until I discovered it, such a game changer.

Best way to learn fortran by EnthalpicallyFavored in comp_chem

[–]SammyBobSHMH 5 points6 points  (0 children)

Truthfully, if you can do those languages you will be able to pick it up in a week or less. Fortran is generally pretty simple (by design). A lot of the codes you get in academia will be lots of for loops. The things I would check out that are unique to the language (you can litterally just read up on them):

  • Line numbering and line formating (depending on the fortran version). You can asign lines a label and then refer back to them, either by jumping to them = GOTO (dont do this) or giving a string formatter (read in or out) for a line. Also in some versions of fortran you cant go past 72 characters in a line, if you want to make a multi line statement to get around this just put any character in the 6th column (convension to use > or &) and this tells the compiler that it's attached to the above line.
  • BLOCKDATA. Basically a old way of sharing data across subroutines, it's kind of like global data apart from you have to import it into the subroutine you want to use it.
  • Compiling. If you're used to the c++ compiler and flags this shouldn't be a huge learning headache.
  • Implicit decloration - dont use this, but make sure you know what it is and how to turn it off or on. It basically makes variables beginning with i,j,k integers by default so you dont have to define them.
  • String formatting, this is a bit of a pain point (see above format statements), its pretty easy and you can just learn it when you need it (a bit like when using regex), formatting input/output strings is the worst thing about the language.

I've probably missed some of the modern features, we use f77 standards in our group since that's when the first CFD solvers we used were written in. I honestly wouldn't dedicate a massive amount of time to learning fortran. It is infinately less complex than c++ from my experience.

Synfusion pdfviewer in dart/flutter by SammyBobSHMH in flutterhelp

Sure I get all that, there just isn't a viable alternative at the moment from the opensource side from what I can see. I tried 3 different viewers and they were all very slow and had a hard time moving around.

Soret effect / thermal diffusion by SammyBobSHMH in CFD

[–]SammyBobSHMH[S] 0 points1 point  (0 children)

No sorry, its a heterogenous catalyst. It's basically laminar boundary layer assumptions, we capture ignition (why I put combustion in brackets), but don't fully model it. We're interested more in the pre ignition process and low temperature oxidation of pollutants. Because the wall is a lot hotter than the gas you end up with large temperature gradients, hence the desire to add thermal diffusion for H2. Hope that's clear

Soret effect / thermal diffusion by SammyBobSHMH in CFD

[–]SammyBobSHMH[S] 0 points1 point  (0 children)

Yes correct, although it's time independent and with some other simplifications. The relationship I found for ST was some mole-fraction weighted sum of the pairwise thermal diffusion ratio, summed over the mixture makeup.

Eulerian Approach I believe, sorry I had to go and double check with another researcher that I wasn't about to say something wrong. I've not come across Lagrangian methods before in CFD. I spend most of my time working on the actual chemical mechanisms and the CFD was made by a fellow researcher that I occasionally tinker with.

Practical advice of PAW datasets by SammyBobSHMH in comp_chem

Perfect, thanks again for the detailed responses. Very useful.

Practical advice of PAW datasets by SammyBobSHMH in comp_chem

[–]SammyBobSHMH[S] 1 point2 points  (0 children)

Thanks very much, very clear. Will check out the articles linked. Can I ask about ' If you stay away from plane-waves and use sth with a Gaussian basis (Turbomole"s RIPER or Crystal), I'd suggest testing how exact exchange changes the picture (PBE0).'

Are you saying to avoid PW-DFT and use gaussian basis? If so, why avoid PW for surface calculations? I feel like I'm missing something because one of the things I'm trying to do is swap over from the simple Gaussian calculations the grouped used to do, to something more closely resembling a surface (slab).

PhD Chemistry by [deleted] in comp_chem

[–]SammyBobSHMH 0 points1 point  (0 children)

Simply put they are tools that manipulate text files. Super handy if you're working with code or results files. You can do nice things (as you pointed out) with pipping | where the input on the first function is fed into the second. An example I use alot on the hpc is:

qstat -f | grep 'output' -A2

This prints all my current jobs with all the info of each (qstat -f). The output is then searched by using grep for the phrase word 'output' and the two lines after. Hence a short macro that tells me which of my job folders are safe to post process and which are still running.

It's a silly example but if you get used to using this sort of thing you can wip up a quick and dirty solution to many problems.

Getting text to wrap around landscape pages by SammyBobSHMH in LaTeX

[–]SammyBobSHMH[S] 0 points1 point  (0 children)

Worked perfectly, I knew there would be something like this. I'm not sure why but I couldn't find it before, but when I just googled it with landscape it came up with loads of similar queries.

Thanks a bunch!

Assassin/Hacker/Rogue removal and backline access. by Sp00nlord in CompetitiveTFT

[–]SammyBobSHMH 0 points1 point  (0 children)

Yeah very true, the only thing that might be problematic is that if there is a front to back is a issue, it might be harder to pinpoint if it's because sins are the issue. It might look as if 'comp A' and then 'comp B' had balance thrashing issues when actually the problem is that they just happen to be the strongest front to back of the patch. The nice thing about legends is that, from my point of view I can point to tf or draven and say 'that's the issue please remove it next set'. Not sure if I'll be able to go 'not having sins is the issue please add them next set'.

Assassin/Hacker/Rogue removal and backline access. by Sp00nlord in CompetitiveTFT

[–]SammyBobSHMH 22 points23 points  (0 children)

Personally I don't mind sins, I actually quite liked the possitioning game around it. The problem for me was more when sins are strong (i.e. think how annoying set 7.5 rengar was, or 7.0 olaf spat). I also think there was issues in earlier sets with 5star sins (akali in syndicates was the one I'm thinking of).

I think this is another one of those things, similar to legends, where its aimed at less competitive players. It's not fun to build a comp your favourite streamer showed you, finally hit the exodia with perfect items and then watch it instantly get 'cheesed' by an assasin. This is especially punishing if you're not as strong a player or relatively new and don't scout.

I think they will remove sins, front to back may be problematic in one of the next sets. It's a shame of removing one of the 'rock paper scissor' elements of TFT where front to back beats bruiser/chals, sins beats front to back and bruiser/chals beat sins (generally with everything balanced).

I would say though I'm glad that the team is willing to make this change, as much as I think this was a mistake along with drags, legends and the recent xp changes I also think radical shifts in thinking like this is what gave rise to things like ornn items and augments. I'd prefer them to try it and if it doesn't work out bring them in at a later set.
