For those who are interested, these are the headphones I use: bit.ly/runningbluetoothheadphones
how abt your normal one
That shirt is the most effective and safest form of birth control a person can use
Can confirm.
Omg that shirt! 😂
Please wear that while defending your thesis at the PhD viva
If you ever decide to propose to Liv, please wear that shirt when you do.
;-; he didn't
Regarding crashing the network, it's happened dozens of times in my department too (I work in climate science at UNSW in Aus.) and is very easy to do. It occurs when people don't properly manage their jobs, specifically setting memory limits. If your job then takes up all the memory on the server it will lock up, become unresponsive and require re-setting (this only takes about 10 minutes) followed by an angry email from the Sys. admin. Luckily I don't think ours is set up in such a way that you can bring down the network by crashing one of the servers - no idea how you would manage that.
The memory probably leaked and as a security measure the system resets as a whole.
Your vlogs are terrific... And they're getting better!
Another great vlog from my favourite vlogger!
Aw thank you
Congrats On your Win Simon. You inspire me a lot.
New subscriber here, I don't understand anything about programming or physics but you somehow kept me entertained - good job
Great vlog. Loved the ending!
Now I need more Simon working/coding very fast montages.
Literally just found your channel today! But honestly I find it so cool that I basically understand all of the coding methods you're talking about despite me being a first year BA student that only started code last September, haha. I'm doing 'Computer Visualisation and Animation' at the National Centre for Computer Animation in Bournemouth (I'm hoping to get into film!) Contrary to what most people assume, we do a fair bit of scripting for modelling, rigging and image production over the course. I just adore Physics, especially having grown up with a Mum working in it and a sister studying it (she just finished her MSc in Birmingham!), so I like to figure out ways of putting my physics interest into my course projects. Just this term I handed in a C program that generates a star map of the Zodiac constellations. I used the HYG database, inputting RA, dec and apparent mag of the stars to plot them with different levels of brightness on a window, then input the constellations to draw them over the top. It is far simpler than it might sound!! Just a bit of maths. But it's my first ever piece of C script (I handed in my first ever Python last month too, which procedurally modelled cityscapes). But anyway.. this is a looong post. I have definitely subscribed! :)
Hey Simon, great video, thanks for the motivation !!! (still have exams) and good luck to anyone else having them as well
Hi Simon, really enjoyed your video series so far! (Alas, I have chain watched them all now) I was thinking of copying a little and doing one of these series for a psychology student (PhD starting October) but I really don't think I can match the charisma, and fatally... I have no Dan.
Hey Simon, your content is amazing and I love your videos. I just had a question. If you were to base your PhD in a field of Physics, other than Climate Physics, specifically Stratosphere-Troposphere Coupling, where would you base your research on, and why?
Hmmmm interesting! The thing that originally got me interested in a physics degree was plasma/fusion stuff so maybe something in that - or I quite liked some of the solid state physics and metamaterials stuff in my undergrad, so I could probably research that quite happily too!
Just when i needed it... Great Content :)
"You get paid to do a PhD?"
"Not much!"
XD
One of the best produced vlogs yet. Very cutting edge
Your vlogs are improving so much now imo! Long time viewer here. Keep it up!
Maybe someone has already suggested this but you should use version control! So if you accidentally ruin your code you can revert it back to what you last "checked in"
Wanted to suggest the same to him! Was searching for "git" and "version control" in the comments section and found yours. :D I've been using Git once I started working and it's been a huge blessing for me. No more worries about file deletions, accidental changes and stuff. It lets you experiment freely with your code. You should definitely try it if you haven't, Simon.
I think he uses dropbox for version control.
Well done on the 10k! Proud of you
I really liked the Vlog!! Its interesting to know more about the coding as ive had only a year of fortran practice
Love your videos! Please keep on making them
I can't get over that shirt.
Do more Kerbal please. Your interactions are amazing.
I just realize that we are in the same year (2009). But you ve already completed PhD degree, while I am going to start my PhD this year. Congrats! I really like watching your vlog.
The app Simon's using for running is called Strava.
After rewriting the same code six times this week for my cosmology research each time correctly, but thinking it was wrong due to me misreading the axis of a graph, thanks for reminding me I am not the only one that makes really dumb coding errors!!!
Hey Simon. Thank you very much for your content, it is very pleasant to follow someone so passionate and humble about what they are doing. Really enjoy watching your content!
I am a Ph.D. student myself in hydrological science. I would be interested to know in a few words what approach you used to couple Python and Fortran scripts if you get a chance?
Thank you. Enjoy the rest of your week at the TH-cam Space and best of luck as you approach the home stretch of your Ph.D.!
great content as always!
On the topic of the server crash, I've seen the suggestion it was resource allocation problems which could make sense if there's something wrong in how the servers are set up. Another possibility is that with the 100% load was for the CPU, it could have been a thermal problem; I'd be surprised if the AC wasn't sufficient but it could have been an automatic emergency shutdown due to hitting a thermal limit. Just another possibility - our uni computers blue screen because of thermal issues in the less well-maintained labs all the time.
What kind of music are you listening when youre working on a pc or laptop?
>tfw you have gcse maths tomorrow morning but Simon uploads
1:45 I'm dying laughing at your shirt! xD
Congrats on the nextup thing!
Simon what is the brand of your bluetooth earphones ?
Regarding the "Oxford network Shutdown", in these situations it is most likely due to the fact that the cluster wasn't configured properly with the proper resource allocation and threshold configs. So it isn't really your fault.
Waking up to a video notification is the best way to start the day :)
Definitely play more KSP with Dan!!
Victims of classic HP laptops spread across Exeter campuses.
Good job on the PhD life vlogs btw!
What computer game was that towards the end where you put the rocket in space?
i love the editing
Hey Simon, what do you ask for when you get your hair cut? Looks good!
Which computer do you use?
And
Your videos are much similar to those of casey neistat
A HP-EliteBook-850-G1!
Hello Simon,
Could you plz tell your headphone model?
1) I'm surprised you're using the BBC weather app instead of the Met office one
2) That t-shirt is a massive warning sign to all women, but it's beautiful
3) My friend crashed the servers by having an infinite loop in his code. Apparently, it's quite common in my department.
What laptop do you have Simon?
Haha you were wearing that t-shirt on the Yogscast stream yesterday 😂
Looking thinner dude, that running is doing work!
Do you cycle? I used to go running but the added speed of cycling made it exercise more enjoyable for me
totally normal after running - "yes i needed that. oh yes"
I'm a fan of the shirt! Where did you buy it from?
What app do you use for running?
@Simon Clark what is your major in exeter ?
That watch is really neat! Where did you get it? :)
how did you learn to code. like I'm learning basics but like I don't know 💩 what to program and where to program. I want to program aagh
Khubaib Intwala programming for its own sake is a grim path. Want to build something (website, mobile or desktop app, useful scripts, ras pi, andrino etc) then just google what you need to learn, ie the best language(s) for the job. Watch some tutorials on that language to get the basics, the google specific problems as you run into them while creating what you set out to.
without watching the film, hearing "ohh, yessss, i needed that"....
Does your 30GB of weekly data generation include your filming?
+InactivePhoenix that's JUST my filming
simon? i have a question and i may seem materialistic by this but how much (on average or estimate perhaps) would i earn if i pursue a degree related to science? ==im asking because science has been my passion since i was a kid but i come from a middle class family in a thirld world country and i am an only child so im afraid of not being able to support my parents in the future :( also, currently, i am an accountancy student and although the analyzation problems and activities make me use my brain a bit, i feel like its not enough and i want to fully use my brain. it sounds weird and my post is getting long but my brain has to keep on turning and cracking and all that thinking stuff, otherwise i feel like a stone on a sidewalk :(
dianne golez During the degree, you will be given money to buy food, clothes, pay bills etc but you will have to get your own job to pay for the degree itself. Jobs in the entire scientific field vary hugely in terms of wages. From 30k a year to perhaps a couple 100k (in dollars or pounds) but it really depends. The most paid people are usually the ones with PhDs. But yeah, to pay for the degree, you will need another job or get your parents to help you out, but while doing the degree you get given money for your basic necessities.
diana banana hi, I'm very late here and I hope I'm not bothering you. Pay for academic research is decent but not great. Pay in some areas of applied science can be very high. And interesting work. Example: a person with a good knowledge of computer network security is in great demand.
Hey Simon I'm an undergrad in America want to pursue a second major in physics in my school. My first major being a political science with a minor in Economics. What are good study tips when preparing for physics exams and mathematics thanks.
Anyone know what type of Bluetooth earphones Simons using ?
Link in the description!
Oh silly me, cheers man haha
Nice watch, what brand is that?
that t shirt is a thing of beauty
Also, is there a way to use your amazon link from the US amazon site??
I don't think so... you'll probably have to search for the item name on the US store I'm afraid!
Aw, oh well! I was hoping to help you out by using it! (assuming it's one of those links that gives you a small percentage or something)
Heh. Interesting video. I am an engineering student but I don't really like coding at all, so I'm starting to think I may be in the wrong line. Cool shirt.
Hey Simon, great video as always. I was wondering if you knew any good books on rocket science and engineering?
I'm afraid not no, sorry!
Hmm thank you anyways, miss your book club videos!
Loved the video.
Fortran is almost fast or faster than c in sci work. Nice to hear it
What is the name of the running app that Simon is using .
maher kassem It's Strava
I think it should be Strava!
SuperMajck
thank you 😘
Relaxchan
thanks❤
your campus is so pretty!
Simon, before before you made up your mind and determined to study physics in the future and apply for physics major in university, did you hesitate? in other words did you ask yourself whether physics is really something you wanna pursue for the rest of your life?
what is that thing with the john cena cover on your shelf? It´s the old "Dr. of Thuganomics"-Cena so it must be awesome
Haha yeah that's John Cena - it was a christmas present from a friend one year and I just love having it around as a joke in the background! Surprised you could see him tbh
What type of headphones does he have?
Good day Sir @simonoxfphys!
Being you are the time-lord, I've been meaning to ask you this question: "Is watching other people get productive, a productive thing to do?"
I swear if someone dislikes another video of his, I will throw arms!
What’s the name of the transition music?
The script might have used too much ram or cpu and caused something like a memory allocation error which could freeze and crash the whole server. There could also be conflicts as there might be many other applications on the same server as well. Just my guess ..
ok for the whole network to crash, you need to do two thing's, overwhelm all server's so that the surge protection kicks in, that's basically linux or windows server or any other noding software seeing that all the computer have hit 100% by one software and thinking that the software is a virus, or you overwhelmed a switch, basically a switch might have burned due to the vast amounts of data transmission that might be happening due to noding. (noding is node ing(node is a individual server rack)) or chill you did nothing and it was an correlated accident, at the same time you sent the program someone by mistake might have turned off a switch or a master node, or something somewhere shut itself off. anyways without more details can't blame it on you.
I see that Hearts of Iron 4 on the backround!!!! ( well a video but still counts)
Just about to submit my PhD proposal which is also a niche, would love if you talked about starting Coding based projects and research?
You're not the first person to suggest this, hmm....
Okay, that is the best shirt I've ever seen! xD
Niche problems can have you feeling so helpless sometimes! >
LOVE the shirt.
YEAH BOI
How the "hell" did you crash the entire network?!
God it's weird watching this as first year in 2021
hi!! do u think biology requires a lot of memorization rather than understanding the concept??at least in physics and maths u have to understand the concept,right??the country where I live in its medical education is totally based on memorization if u wanna be a doctor u don't need be good at maths but u have to be super good at memorizing stuff but I think if a person has good problem solving skills he will be a better doctor but in my country this theory is considered as a bullshit theory.cause the more u memorise ,the more u earn.
Minori ruba where are you from ?
Biology does require a lot of memorisation, some understanding of chemistry, mathematics and engineering will definitely help a lot, but unless you go to things like chemical processes in the cell, it's mainly memorisation.
That being said: Don't underestimate the memorisation involved in mathematics. Lots of definitions and theorems to keep track of
but u also have to use ur logic and brain in maths.in biology u have to memorise like crazy.(at least I think so)!my brain just gets freezed when I try to memorize theories because ur brain is there to think,solve problems it's not a machine to remember every single line of your books.
Minori ruba I hope this isn't America because while I know there is a lot of memorization involved you have to understand the concepts of biology and chemistry and calculus in order to be able to understand the future concepts of pathology...
Maybe they did some load balancing (i.e. they try to spread the work equally amongst the servers).
why are you using a as an index??? my programming class teacher taught us that you use the letter I as an index and if I is already used than use the letter J
+gabie dubin that's the convention I normally use, but in the context of what I was doing (i,j) is conventionally reserved for iterating through latitude and longitude, so when I needed to iterate through something else I just picked a new letter to be an index
Great video! The t-shirt is terrible though.
now, we are learning matlab. What is the advantages of fortran language?
Arda Kayaalp it's very fast. Can be parallelised very well. Can be optimised very nicely. Similar to C++ but more used in science
MORE OF THE KERBAL.
Hey Simon can you make more Livestream-Podcasts , I love em
Hopefully I'll be doing another livestream soon!
Interesting how you completely took down the network. The cause of it can vary alot. Maybe it is you just completely requesting all the load of the servers. Or your code was kinda crappy and got some memory leaks or something. Like, it could have been your code which just ran to the infinity.
when you have to rewatch, because you spent the whole time focusing on Ainsley
cool background music.
that t shirt is covefefe af!
where did you buy that shirt
Pixel gurllllll!!!!
Waiiiit, did you changed the title? :D
The ending haha.
I have never seen anyone enjoy running so frequently. It's too painful to do any other time than when you miss your bus, and that's coming from someone who fights 5 hours a week and lifts weights 5 hours a week.
