You can store the Merkle trees inside of a SQLite database as extra columns attached to the data.

That way you get the benefits of a high-level query language and a robust storage layer as well as the cryptographic verification.

In fact, there is a version control system called Fossil which does exactly that:

https://fossil-scm.org/home/doc/trunk/www/fossil-v-git.wiki

The baseline data structures for Fossil and Git are the same, modulo formatting details. Both systems manage adirected acyclic graph (DAG) of Merkle tree structured check-in objects. Check-ins are identified by a cryptographic hash of the check-in contents, and each check-in refers to its parent via the parent’s hash.

The difference is that Git stores its objects as individual files in the .git folder or compressed into bespoke key/value pack-files, whereas Fossil stores its objects in a SQLite database file which provides ACID transactions and a high-level query language. This difference is more than an implementation detail. It has important practical consequences.

The SQL query capabilities of Fossil make it easier to track the changes for one particular file within a project. For example, you can easily find the complete edit history of this one document, or even the same history color-coded by committer, Both questions are simple SQL query in Fossil, with procedural code only being used to format the result for display. The same result could be obtained from Git, but because the data is in a key/value store, much more procedural code has to be written to walk the data and compute the result. And since that is a lot more work, the question is seldom asked.

The right balance on this is to set it up to only trim whitespace on lines that you have edited, and only on-save.

Emacs has ws-butler for that behavior: https://github.com/lewang/ws-butler

If undefined behavior is triggered anywhere in the program, then it is allowed by the standard for the process to ask the anthropomorphized compiler to punch you.

Small correction to an otherwise great explanation: SSNs are not recycled after death.

**Q20:  *Are Social Security numbers reused after a person dies?*****A:  No. We do not reassign a Social Security number (SSN) after the number holder’s death. Even though we have issued over 453 million SSNs so far, and we assign about 5 and one-half million new numbers a year, the current numbering system will provide us with enough new numbers for several generations into the future with no changes in the numbering system.

For the first part, I was like, yeah, that’s pretty much how all C++ GUIs work: a markup file describes the structure, a source file controls the behavior, and a special compiler generates more C++ code based on the markup file to act as glue.

That’s all pretty standard, and it’s annoying, but I didn’t really get why they were making such a big deal out of it.

Missing documentation is also annoying but not uncommon for internal widgets.

What really elevates this from simply annoying to transcendentally bad, is the lack of error messages, the undocumented requirements that resource IDs be sequential, and the mandatory IDE plugin. That’s all unforgivable.

I’ve always thought it was weird how there are two media properties involving genderless gem people.

Great article, thank you for sharing.

It is doable for many young professionals who work office jobs out of college, do not have dependents, and live with a roommate for a few years while getting established in their careers, finding a spouse, and then moving out to the suburbs.

This is just about possible in NYC if you 1) work in a high-rise by a station 2) commute during peak times with frequent trains 3) live in a high-rise by a station.

For example: Downtown Brooklyn or Exchange Place high-rise <=> WTC.

The other option would be to live within walking distance. A <20 minute walking distance to a downtown or midtown office is reasonable.

I don’t know the details of the situation in Poland, but Poland does have an 87% home ownership rate.

I haven’t tried this, but if you just need the parent to call waitpid on the child’s pid then you should be able to do that by attaching to the process via gdb, breaking, and then manually invoking waitpid and continuing.

I hope you’re on a long LTS release my friend

100% equals one full core. Higher numbers are possible for multithreaded processes.

+1. The joy of camping (for me) is that your experience is directly related to your preparation. You plan your location, activities, meals, sleeping arrangements, and companions, doing all of the research and investment up front to make each of those work well, taking into account weather and conditions, and then you get to enjoy a trip where everything goes well with people you care about, with the satisfaction that the experience that you are having is the direct result of your actions.

Of course, the pain of camping is that any and all of the above can go wrong, and then, indeed, it’s probably gonna suck.

Coffee crisps and ketchup chips are the two things I always buy when I’m in Canada. I wish we had them in the States.

Fair enough. I think it’s okay if you’ve experienced a place, given it a shot, decided it wasn’t for you, and moved away.

One thing I’ve noticed in NYC however, is how many people have an uninformed and strong default opinion that anywhere besides the west or east coast in unlivable, and that bothers me.

Your comment is reasonable, but a lot of the comments to this post reflect that same caustic attitude and it saddens me.

Austin is a nice city. With all due respect, and as someone who grew up in Texas but now lives in NYC, it is exactly this kind of condescension that makes a lot of Texans dislike people from the coasts.

The inverse square law only applies to undirected things, because the surface area of a sphere is proportional to the square of radius. The parent specified directed, like a laser.

So what you’re saying is, it is true that I will no longer have French installed.
