While this has some of the metrics features that Ciro Santilli wants to implement for OurBigBook.com, it limits the number of articles your readeres can read.
How the fuck can you publish on a website that limits the number of views for your articles?!?! When all it has is static pages + some metrics?!?!
Evil. Just learn to use GitHub Pages for God's sake.
Poor renaming choice.
Or: how to learn X.
This pops up on Reddit every week.
That is the wrong question.
The right question is: what is the most awesome project I can do to improve the world?
Then, once you decide to try one, if that involves programming, only then learn to program to achieve that goal. And don't stop learning what's needed until you either get the thing done, or decide that it is actually not a good idea, or not possible, or that there is something else more important to be done first.
But if doesn't involve programming, then don't learn to program, and learn whatever you actually need to reach that goal instead.
Having that goal is the only way to be motivated to do something.
This is the essence of backward design.
Another very important point to keep in mind is: Section "When in doubt, choose the course that has the most experimental work".
A fancy name for astronomy ;-)
Ciro Santilli wants to rule this with OurBigBook.com.
It boggles Ciro Santilli's mind that people use mailing list to collaborate on projects!
The only explanation is that the dinosaurs who created the projects are unable to adapt to new superior technologies.
Yes, Ciro is talking to you, big fundamental projects from last century: Linux kernel, GNU Compiler Collection (gcc.gnu.org/lists.html), Binutils (sourceware.org/binutils/), etc.
Some of you are already using Bugzilla for the bugs, so kudos. But if you've seen their benefit, why you still use the mailing list for patches?
Advantages of mailing lists:
- threaded replies, which almost no issue tracker has. GitHub feature request: github.com/isaacs/github/issues/837
Disadvantages: everything else:
- cannot subscribed to a single thread. Which forces you to create an email filter for each one of them you subscribe to.
- no metadata, notably the notion of closing / merging, but also upvotesYou have to read thirty messages before you can know if the bug was solved or not.
- it is insanely hard to reply to messages from before you were subscribed: webapps.stackexchange.com/questions/23197/reply-to-mailman-archived-message/115088#115088This forces everyone to subscribe to all lists, and then set up email filters to not be flooded with emails.
- hard to apply patches locally to test them out: stackoverflow.com/questions/5062389/how-to-use-git-am-to-apply-patches-from-email-messages/49082916#49082916Unless they use Patchwork, which adds one more website on top of the mess.And then Gmail corrupts your patches, and you are forced to use
git send-email, which does not work on some network configurations: stackoverflow.com/questions/28038662/how-to-solve-unable-to-initialize-smtp-properly-when-using-using-git-send-ema or setup ThunderBird. - often have to subscribe to post at all, thus cluttering your inbox further
- you can edit posts to make them clearer.Yes, people could vandalize their answers when they get mad, and threads might stop making sense after edits. But this can be solved with an undeletable post history like Stack Overflow has (but not any other tracker does).Or archive.org :-)In any case, what do you think will happen more often and have greater impact:
- people vandalize their posts
- people fix their silly typos and improve content
- searchable by author, keyword, etc. without Google. Yes, mailing list trackers could have decent implementations to overcome that. But no, GNU Mailman which everyone uses does not have it. Google barely indexes it.And I don't think Google properly indexes many of the mailing list archives for some reason: I never get hits for my own posts a week later, while I often do on GitHub issues.
- people have to learn about top posting vs inline posting, and this requires infinite education of new users
- Line comments in code reviews like GitHub and GitLab.On mailing lists: either put a comment in the middle of a huge patch and let other people find it, or (more likely) copy paste the part of the patch that you are talking about.
- most mail web UIs suck.OK, this is not an unsolvable or intrinsic problem, but still a problem.E.g.:
ezmlmit is not possible to see the entire content in a single page: gcc.gnu.org/ml/gcc/2015-07/threads.html.Unless you like reading threads backwards and with 4 levels of>quotations.The alternative: do like LLVM and send attachments. Yes, I we all love opening up attachments on our browsers.The real solution: everyone can create branches and pull requests. Also has the benefit of running CI on the pull requests.
Not sure:
- you can have infinitely many trackers to replicate data in case apocalypse happens in some part of the world.Although I'm not sure this is an advantage, as you don't know anymore which one is the canonical trackers an advantage, as you don't know anymore which one is the canonical tracker.And all web interfaces already have an API to export messages, and someone has already scripted it to import from any web UI to any web UI for you.And GitHub offers infinite precise history transparently on its API.
As of 2019, the silicon industry is ending, and molecular biology technology is one of the most promising and growing field of engineering.
42 years of microprocessor trend data by Karl Rupp
. Source. Only transistor count increases, which also pushes core counts up. But what you gonna do when atomic limits are reached? The separation between two silicon atoms is 0.23nm and 2019 technology is at 5nm scale.Such advances could one day lead to both biological super-AGI and immortality.
Ciro Santilli is especially excited about DNA-related technologies, because DNA is the centerpiece of biology, and it is programmable.
First, during the 2000's, the cost of DNA sequencing fell to about 1000 USD per genome in the end of the 2010's: Figure 2. "Cost per genome vs Moore's law from 2000 to 2019", largely due to "Illumina's" technology.
The medical consequences of this revolution are still trickling down towards medical applications of 2019, inevitably, but somewhat slowly due to tight privacy control of medical records.
Ciro Santilli predicts that when the 100 dollar mark is reached, every person of the First world will have their genome sequenced, and then medical applications will be closer at hand than ever.
But even 100 dollars is not enough. Sequencing power is like computing power: humankind can never have enough. Sequencing is not a one per person thing. For example, as of 2019 tumors are already being sequenced to help understand and treat them, and scientists/doctors will sequence as many tumor cells as budget allows.
Then, in the 2010's, CRISPR/Cas9 gene editing started opening up the way to actually modifying the genome that we could now see through sequencing.
What's next?
Ciro believes that the next step in the revolution could be could be: de novo DNA synthesis.
This technology could be the key to the one of the ultimate dream of biologists: cheap programmable biology with push-button organism bootstrap!
Just imagine this: at the comfort of your own garage, you take some model organism of interest, maybe start humble with Escherichia coli. Then you modify its DNA to your liking, and upload it to a 3D printer sized machine on your workbench, which automatically synthesizes the DNA, and injects into a bootstrapped cell.
You then make experiments to check if the modified cell achieves your desired new properties, e.g. production of some protein, and if not reiterate, just like a software engineer.
Of course, even if we were able to do the bootstrap, the debugging process then becomes key, as visibility is the key limitation of biology, maybe we need other cheap technologies to come in at that point.
This a place point we see the beauty of evolution the brightest: evolution does not require observability. But it also implies that if your changes to the organism make it less fit, then your mutation will also likely be lost. This has to be one of the considerations done when designing your organism.
Other cool topic include:
- computational biology: simulations of cell metabolism, protein and small molecule, including computational protein folding and chemical reactions. This is basically the simulation part of omics.If we could only simulate those, we would basically "solve molecular biology". Just imagine, instead of experimenting for a hole year, the 2021 Nobel Prize in Physiology and Medicine could have been won from a few hours on a supercomputer to determine which protein had the desired properties, using just DNA sequencing as a starting point!
- microscopy: crystallography, cryoEM
- analytical chemistry: mass spectroscopy, single cell analysis (Single-cell RNA sequencing)
It's weird, cells feel a lot like embedded systems: small, complex, hard to observe, and profound.
Ciro is sad that by the time he dies, humanity won't have understood the human brain, maybe not even a measly Escherichia coli... Heck, even key molecular biology events are not yet fully understood, see e.g. transcription regulation.
One of the most exciting aspects of molecular biology technologies is their relatively low entry cost, compared for example to other areas such as fusion energy and quantum computing.
This is the most important technical tutorial project that Ciro Santilli has done in his life so far as of 2019.
The scope is insane and unprecedented, and goes beyond Linux kernel-land alone, which is where it started.
It ended up eating every system programming content Ciro had previously written! Including:so that that repo would better be called "System Programming Cheat". But "Linux Kernel Module Cheat" sounds more hardcore ;-)
Other major things that could be added there as well in the future are:
- github.com/cirosantilli/algorithm-cheat
- computer architecture tutorials with gem5
Due to this project, some have considered Ciro to be (archive):which made Ciro smile, although "Linux kernel documenter God" would have been more precise.
some kind of Linux kernel god.
