Social recommendations and mentions

We have tracked the following product recommendations or mentions on various public social media platforms and blogs. They can help you see what people think about CoCalc and what they use it for.
  • Show HN: I made a better Perplexity for developers
    Is there something like this (maybe this?) that provides an API so I can integrate it like any other model into my own website (in this case, I tried asking the devs, but got ignored. - Source: Hacker News / about 1 month ago
  • A list of SaaS, PaaS and IaaS offerings that have free tiers of interest to devops and infradev — (formerly SageMathCloud at — Collaborative calculation in the cloud. Browser access to full Ubuntu with built-in collaboration and lots of free software for mathematics, science, data science, preinstalled: Python, LaTeX, Jupyter Notebooks, SageMath, scikitlearn, etc. - Source: / 5 months ago
  • Ask HN: What is going on regarding quality of service for API access to LLM's?
    I saw in the latest ChatGPT plus announcements that you get better speed if you pay them $20/month. This made me wonder how the speed of the plus version of ChatGPT compares to the API that we pay for (to integrate ChatGPT into We have had solid usage over the last 2 months, and I keep track of exactly how long the complete response takes for each api request. I just checked the stats and... - Source: Hacker News / about 1 year ago
  • A list of apps that helped me through my "de-Googling" process
    Google Colab: CoCalc offers an online, computational notebook experience that could be comparable to Colab. It was initially funded by Google and the NSF, but is mostly funded by paying users these days. Source: about 1 year ago
  • Gpt4free repo given takedown notice by OpenAI
    They put my site, which has chatgpt API integration, into this gpt4free. As a result, I had to modify to require sign in before providing the ChatGPT functionality to visitors, and I also explicitly updated our terms of service to clarify how our API can be used. I made a pull request - Source: Hacker News / about 1 year ago
  • Ask HN: Who has deployed commercial features using GPT4?
    1. I'm integrating ChatGPT extensively into This integration makes a lot of sense, because cocalc is a platform in which relatively inexperienced students use Jupyter notebooks, linux terminals and Latex. So far, the most popular feature by far is a "Help me fix this" button that appears above stacktraces in Jupyter notebooks. 2. One software engineering challenges is that ChatGPT often... - Source: Hacker News / about 1 year ago
  • Codon: A high-performance Python compiler
    What I want to know is: "can I add Codon to a site like that I host as long as users of Codon explicitly agree to only use it in a way that is compatible with the license?" I have absolutely no idea if that would be allowed by the rules or not. - Source: Hacker News / over 1 year ago
  • — (formerly SageMathCloud at — Collaborative calculation in the cloud. Browser access to full Ubuntu with built-in collaboration and lots of free software for mathematics, science, data science, preinstalled: Python, LaTeX, Jupyter Notebooks, SageMath, scikitlearn, etc. - Source: / over 1 year ago
  • Ask HN: Why hasn't the Deep Learning community embraced Julia yet?
    We offer Julia at both via Jupyter notebooks and Julia’s own Pluto notebooks. That said, Julia tends to be a lot more memory intensive than other language we support, so the free tier is not as useful. - Source: Hacker News / almost 2 years ago
  • SelfHosted Calculator (Math, Physics)
    Also, here is the link to the official CoCalc site. Link: "". The Docker version I linked above is a minimal version of this site (but still quite comprehensive for a home lab). Source: almost 2 years ago
  • Is there any solution in Texmaker to calculate Logarithmic Integral Function Li?
    Log_integral is a function built into SageMath, a free computational mathematics language built on top of Python as a freeware alternative to Mathematica, MATLAB, and Maple. I have used it extensively. It is available for free download or with a free account on their online platform CoCalc. The free account has limited server time, so complex computations tend to be slow, but it'll get the job done. Also, see my... Source: almost 2 years ago
  • Easiest way to run Jupyter Notebooks?
    It may also be worth looking at cocalc from sagemath. It does all the Jupyter notebook stuff (and a TON more), and has collaboration tools. This will require a free account, but the trade off may be worth it. They also have a bunch of stuff focused around education. Source: almost 2 years ago
  • Need some starting advice
    Something you might find helpful with Python is creating a Jupyter notebook (you can create one for free online here: Source: almost 2 years ago
  • Render mathematical expressions in Markdown On GitHub
    There's currently around 100 LaTeX functions listed as "Not supported" in the Katex docs at I've been trying hard for a while with my site ( to use only katex, but that's definitely never going to happen. Users frequently hit missing functionality, e.g., they have lots of notebooks that use "\mbox", so it's critical to support full mathjax. I... - Source: Hacker News / about 2 years ago
  • Ask HN: What ML platform are you using?
    I see some great recommendations in the thread already, but I think is definitely worth checking out if you consider yourself to still be more of a learner. Their focus seems to really be on helping people who are new to the field get started. It offers familiar Jupyter Notebook-like features so you should feel right at home. I have no affiliation with them whatsoever :) Just a fan of what... - Source: Hacker News / over 2 years ago
  • Unix in the Browser Tab
    What's different about this compared to something like CoCalc? There I get a fully functioning Linux terminal on typically a Ubuntu disruption (so backed up by a full OS), and a whole suite of other things like sagemath, R, Julia, Octave. Source: over 2 years ago
  • Can you run R Studio on an iPad?
    There are also a few browser options that you don't need an account for like and if you don't need to do heavy lifting. Source: over 2 years ago
  • Why is Maple a thing?
    You can also call PARI/GP using Sage too. I don't know why Sage having a strict superset of the features of GAP and PARI/GP combined makes it an ugly conglomeration; this is a positive in my mind. Also, being able to write in Jupyter notebooks with Sage is a very nice feature, especially for big projects. You can do this with GAP too, but it's not very nice whereas it comes preinstalled with Sage. As far as I... Source: over 2 years ago
  • Turns Jupyter notebooks into standalone web applications and dashboards
    Have a look at (I'm not affiliated), they provide essentially what you want (although I doubt at the price point you are talking). - Source: Hacker News / almost 3 years ago
  • How to work with Sage locally
    Although you can use Cocalc to create mathematical documents with LaTex this can be slow when working on big projects, for that reason you can do the following to use LaTex with SageMath from your local computer, and even working without internet. Follow the next steps:. - Source: / almost 3 years ago
  • Online version of Maple
    Wolfram Alpha is a good option from my point of view. If you want an alternative, you can also check Cocalc. Source: almost 3 years ago
