Git Notes 4 years ago

No that's not the same thing, in fact that'll just do a git rebase, changing the commit itself and all commits after that one. Pretty much the polar opposite of what you want!

IntelliJ products try to provide a common interface and common naming for all "VCS" operations, whether it's Git/Mercurial/etc. In practice this obscures the actual Git operations though and requires learning yet another set of "abstract" IntelliJ-specific names for the same thing. I wish they'd stop doing that, it's really confusing and inaccurate.

No magic and the same photons, but you can have the hardware sensor read them out differently. Specifically using varying amounts of analog gain / amplification before doing analog-to-digital conversion, minimizing noise. This varies based on camera design.

See the "ISO-Invariance and Downstream Electronic Noise" part here for a better explanation: https://www.lonelyspeck.com/how-to-find-the-best-iso-for-ast...

The article mentions the Sony A7S as an example, with the sensor showing marked improvements in SNR when reaching ISO 100, 200, 1600 and 3200, while behaving ISO-invariant wrt. noise in between those values.

I don't often hack my own tools either, but it's great to have the possibility to do so.

When you really need that bug fixed for your edge case or platform, it's much easier to submit a patch rather than wait around for someone else to fix it.

Ventura even drops support for the 2016 (Touchbar) Macbook Pros which is frustrating. The machines are certainly powerful enough. But support for Intel Macs will probably be dropped sooner rather than later.

Usually the whole row is copied, updated, and then appended to a different file on disk. After some time a job runs that removes the unused rows by deleting them for good, thus rewriting files and compacting the database. This has lots of advantages, on a small scale resilience against power outages (journaling), and on a large scale you can e.g sync a second DB / backup by just streaming appends.

Simplifiying a lot here of course. E.g if your DB uses MVCC (multiversion concurrency control) old values cannot be removed until the last transaction is done seeing them.

Of course if you write your own storage engine you can do whatever you want. I wrote one for MariaDB a few years ago and you basically just have to implement the minimally required interfaces for it to work.

DBs traditionally have these technical details figured out pretty well, and the line between what is part of the DB and what is done by the OS can be blurry at times.

I guess a the height of hypercard, that really wasn't really on people's radar.

It didn't matter yet. People were shipping the software they made in HyperCard to customers on floppies or CDs. IIRC these were self-contained executables, so you didn't need to have HyperCard installed for it to run. One of the most famous examples of this was Myst: https://en.wikipedia.org/wiki/Myst.

I wonder why they couldn't go just a bit wider to make it 2880x2880 (1:1 and the same number of pixels as 4K), instead of 2560x2880.

I'd also recommend the classic "The Cathedral and the Bazaar" essay by Eric Steven Raymond:

http://www.catb.org/~esr/writings/cathedral-bazaar/cathedral...

From Wikipedia:

In 1998, the essay helped the final push for Netscape Communications Corporation to release the source code for Netscape Communicator and start the Mozilla project; it was cited by Frank Hecker and other employees as an outside independent validation of his arguments.

Netscape's public recognition of this influence brought Raymond renown in hacker culture.

With the Advantage 2 you got 4 extra keycaps in the box: 3 Mac keys and an additional Alt key to replace the Windows one.

For the Advantage 360 they're saying 11 additional keycaps in the box. I'm sure one of those is a Windows key replacement.

It absolutely is written down. The issue is that the results you get from modeling systems using queuing theory are often unintuitive and surprising. On top of that it's hard to account for all the seemingly minor implementation details in a real system.

During my studies we had a course where we built a distributed system and had to model it's performance mathematically. It was really hard to get the model to match the reality and vice-versa. So many details are hidden in a library, framework or network adapter somewhere (e.g buffers or things like packet fragmentation).

We used the book "The Art of Computer Systems Performance Analysis" (R. Jain), but I don't recommend it. At least not the 1st edition which had a frustrating amount of serious, experiment-ruining errata.

You can register domains for >1 year. You'll still need to renew it every year but you'll have a buffer in case something goes wrong.

I've found - after trying several apps and custom scripts to do OCR - that the easiest most convenient solution is to just get a printer/scanner combo that does the PDF & OCR directly in hardware. That usually means something targeted towards SMBs that works standalone (in my case a Canon). I.e. specifically not a consumer device: the consumer units usually rely on separate client-side software for doing the OCR processing which complicates the workflow.

IMHO the issue is getting a genuine one. There are a lot of fake chargers around and even reputable retailers get duped by suppliers. So unless you can buy from Samsung directly, I think Apple is the safer bet. You can walk into any of the Apple Stores or order directly and be 100% sure you're getting the genuine product.
