ROOT for Google Colab - Optimized Binaries Pre-built ROOT binaries optimized for Google Colab environments. Download ready-to-use ROOT installations for seamless integration with your Colab notebooks.

Since 2019 I maintained instructions and ROOT build that runs on Google Colab. But every couple of months I had to re-do it because Colab updates. But Now I automated this process and it will always be updated and published here melashri.net/ROOT. I wish it could be an official page on root.cern.

My vote would be for anyone who will force using "+ + + -".

You made me realize that inspire-hep does actually provide an API. That would help answering these questions in some automated way. This is the basic list of papers according to their citation count in hep-ph. gist.github.com/MohamedElash.... analysis can be done on the saved csv file.

Great, There are trade-offs of course. But for most part I found multi containers extension which is well integrated in Firefox is good enough to replace profiles anyway. (Not that Firefox doesn't do proper profiles _.

Zen Browser Beautifully designed, privacy-focused, and packed with features. We care about your experience, not your data..

I would suggest Firefox called zen as a replacment of Arc

My dream app which I want to write someday will be an arxiv and CDS/inspirehep reader that you subscribe to categories and topics(keywords) and it will give you latest papers per day organized for you just to read. Without emails or LLM summary or all of that.

I envy the name. anyway please put me in touch with the people behind this project. My CERN user is "mohamed.elashri" to combat spam bots here.

Thanks, that would be great. I think I heard about this project and if I remember correctly it is names "chatLAS" which is good name that would be unique to ATLAS. I think this is my end goal too but but taking more controlled upgrade steps (also learning how to do them)

I don't have enough social circle (or social life in general actually) in LHCb to ask and don't want to announce this project for collaboration yet. So announcing here just in case I'm lucky to find someone πŸ˜….

I have a side project. It is custom semantic search for LHCb papers. The end goal is to construct a knowledge base for LHCb (not only papers). Currently I have a web app that takes a query and then give you the 10 papers relate most to your query. Looking for a small number of beta testers.

The trend represents a convergence of measurements toward the true value as statistical precision improved. This is supported by the fact that latest measurements have smaller uncertainties. Also it allows only "small deviations from lepton universality"

It seems that sometimes it pays to be a particle physicist!

Preferably next happy moment would be beyond SM discovery or Magnetic Monopole detection. Something like that and then I could die in peace!

First time to feel privileged in my life was yesterday during my French visa appointment. Once they knew I have CERN affiliation. I was prepared with every official paper I had on me and they just asked for passport and invitation letter. Other people before me had to submit dozens of papers.

My theory is that overleaf issues is related to their general deployment of AI error assistant. I was part of beta test and now got an email saying they are moving it from lab to general availability. Also my experience with it is that it is not worth it. And it is $60 annual add-on.

05.12.2024 15:20 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

or if you feel ambitious enough, self host your overleaf instance (although it doesn't come with pro features) but it will definitely have more compiling time. github.com/overleaf/too...

Overleaf is down. If you have a paper deadline then my condolences. This is a good chance to remind you to use sync to Git/Github or Dropbox for all your documents on Overleaf. This could come handy in situations like that.

For me it is called like it is imported "np".

I tried brave in the past on Mac. But I did not like it and also I wanted to support Firefox browser share. I like ublock origin extension and it works better on Firefox. I don't use chrome or any of its forks. I just couldn't find a meme picture about Firefox :D.

I also upgraded my Linux mini PC RAM to 64GB so that I can have more food to the the monsters called JavaScript-engines/HTML-parsers. In English, they are called "Browsers".

I hate to have more than 10 open tabs on my browser. But during my shifts (which I do online) I have to open many more than that. I get confused all the time. My solution is is use zen browser "Firefox fork" and then assign workspace for shift related stuff and have a quick look every hour.

So Deepseek announced their R1 lite model which use reasoning and is competing with o1 performance. Qwen2.5 line of models are impressive specially the coder versions. There are rumors about qwen3.0 coming. Open source (weights) models seems to be living the golden age. If only GPU prices decrease 🀦

My experience with CERN's SSH 2FA My personal experience with 2FA on lxplus ssh connections.

It will be like browser access. it will just ask you about the 2FA code after connecting to lxplus (others?). It will be cached too so you don't have to do it multiple times in s row. Also ssh keys will still work. I actually wrote a blog post on that

To be honest, these attacks were common since birth of the web it is nothing new. But the sophisticated attacks are the new developments. LLMs also make it easy for script kiddies to write generic brute force attacks scripts and use it. You can scan whole ipv4 entire space in couple of minutes

I also meant development nodes not the trigger production systems. No one is testing and developing into production. Those are still offline testing nodes. So while important. Their downtime is not disastrous like online trigger system. That is why I did not talk about this point in my thread.

And here is the thread although I couldn't find a source on number of attacks per day so that I can up with estimation based on reported CERN security reports. One can parse information from monthly digest and extrapolate better number but those are internal information.

This is my chance to thank them publicly and remind everyone that annoying little things like permissions and 2FA (I am part of test-piloting 2FA with SSH connections) are a small price to pay to help maintain a secure computing environment.
