Same. If I am reading for please, I am reading the book sequentially and love the convenience of ebooks. If I am reading a reference or text book, I like being able to quickly flip between (physical) pages and skim previous chapters for a section I want to reread.

From a quick look at the repo, it is end-to-end testing for web applications.

Also, it seems that their big selling point is a verbose, English like syntax.

It is mutually assured destruction. The job seeker AI spams out a resume to every listing and the hiring AI rejects all applicants for not meeting some unknown criteria. In the end, no worker can find a job and no employer can get applicants. Companies go back to only hiring friends and families of existing employees.

I am used to seeing ring buffers implemented using an array. They are FIFO if you write to the maximum offset and read from the minimum offset but they are double ended if you have a method to read from the maximum offset and write to the minimum offset.

Why would you use a library or framework when you can code everything from scratch? It probably depends on how good the VSCode extension is vs how bad the IDE is.

For the languages I have tried (mostly GoLang plus a bit of Terraform/Terragrunt), VSCode plugins can do code highlighting, can highlight syntax and lint errors, can navigate to a methods implementation, the auto-complete seems to pick random words from the code base, and can find the callers for a method. It is good enough for every day use.

IDEs I have used (Eclipse for Java, PyCharm, InteliJ for Kotlin) offer more. They all have starter templates for common file types. The auto-complete is much more syntax aware and can sometimes guess what variables I intend to pass in as arguments. There is refactoring which can correctly find other usages of a variable and can make trivial code rewrites. There are generators for boilerplate methods. They all have a built in graphical debugger and a test runner.

I was a bit surprised that deque is implemented as a linked list and not, for example, a ring buffer. It would mean that index reads would be constant time (though insert and delete at an index would be linear time), the opposite of using a linked list.

TAOCS has a reputation for being very deep and thorough, not for being a good introductory text. One of my professors said that in his (very long) industrial career, he only met one person who actually read the books beginning to end but everyone looks something up in them once or twice.

That has been my experience. I once needed to find out how to solve a very specific problem (I think it was calculating statistical values on an infinite stream). I found the single copy of TAOCS in the office reference library, read the relevant section, and implemented the suggested algorithm.

Maybe it is just my experience, but in the last decade, employers stopped trying to recruit and retain top developers.

I have been a full time software engineer for more than a decade. In the 2010s, the mindset at tech giants seemed to be that they had to hire the best developers and do everything they could to keep them. The easiest way to do both was to be the best employer around. For example, Google had 20% time, many companies offered paid sabbaticals after so many years, and every office had catering once a week (if not a free cafeteria). That way, employees would be telling all of their friends how great it is to work for you and if they decide to look for other work, they would have to give up their cushy benefits.

Then, a few years before the pandemic, my employer switched to a different health insurance company and got the expected wave of complaints (the price of this drug went up, my doctor is not covered). HR responded with “our benefits package is above industry averages”. That is a refrain I have been hearing since, even after switching employers. The company is not trying to be the best employer that everyone wants to work at, they just want to be above average. They are saying “go ahead and look for another employer, but they are probably going to be just as bad”.

Obviously, this is just my view, so it is very possible that I have just been unlucky with my employers.

pip is a perfectly usable package manager and is included in most python distributions now. Is it perfect? No, but it is good enough for every team I have been on.

Why should we keep leap seconds? Let noon drift by 1 minute per century (or whatever).

I always feel a little paranoid when I explicitly close transactions, connections, and files (for quick running scripts, the OS will close the file when my process exits and for long running applications, the garbage collector will close it when the object leaves the scope). Then I read a blog post like this an remember that it is always better to explicitly free resources when I am done with them.

• Encrypt the data at rest
• Encrypt the data in transit

Did you remember to plan for a zero downtime encryption key rotation?

• No shared accounts at any level of access

Did you know when account passwords expire? Have you thought about password rotation?

• Full logging of access and activity.

That sounds like a good practice until you have 20 (or even 2000) backend server requests per end user operation.

All of those are taken from my experience.

Security is like an invasive medical procedure: it is very painful in the short term but prevents dire complications in the long term.

C++ is unique in that it is wildly dominant in its niche. I am sure that any developer who has worked with another object oriented, manually memory managed, systems programming language (are there any other popular ones out there?) should have no trouble picking up C++.

It is better to find a developer that has experience with the language features you use rather than one that is experienced in the exact language you use. For example, I work on distributed systems in Java/GoLang/Python. We want candidates that understand how to write concurrent logic and stay away from people who are just Java web developers.

The big issue is doing a coding interview with candidates. We have a standard straightforward problem that candidates need to solve by filling in a stubbed out method. We have it in Java and have ported it to GoLang. If we have to interview a candidate who does not know either of those languages, we would need to find a language that the candidate knows and we know well enough to port the problem to. We would also have some difficulty digging in to design specifics like choice of concurrency primitives.

I have been an individual contributor at large corporations for more than 10 years. Every time I have had a colleague promoted to manager, they always planned to stay technical and keep coding. Every one of them, without fail, stopped coding because they were too busy.

Thinking back to my managers who left for other roles, only one quit to work in higher management, the rest all went back to working as developers.

I worked at giant, globally distributed companies (15-25k employees), so I imagine that my experience is not typical.

Did you find the answer to your question, and if not, could you explain it better?

Also, a quick tip: if you are using Python 3, you don’t need to join your variables before passing them into print. print accepts any number of arguments, converts them to strings, and prints them as a single line separated by spaces (which is exactly what your code seems to be doing).

Kotlin jvm is extremely stable

I don’t want to use Kotlin on (just) JVM. The reason I am working with Kotlin is Kotlin Multiplatform (so JVM and JavaScript). The JavaScript side is where all of my frustrations have come from.

I also like checked exceptions. I like having a compile time check that I thought through error scenarios.

Is it perfect? No, but it should be iterated upon, not discarded.

FYI, catching and rethrowing as an unchecked exception is a pretty bad anti-patern (and a foul code smell).

The point of using a cache is to have data in memory and not on disk. From what I can tell, Postge Unlogged tables are still written to (and read from) disk. It is just that the write is done in an unsafe way.

The article explains how one would go about benchmarking performance but forgets to actually include performance metrics. Luckily they link to another write up that does. Using an Unlogged table vs. a regular table reduces write times about 45% and gives you about 3 times as many transactions per second. It is not nothing but it is probably not worth the code complexity vs. writing directly to a persistent table.

Even the “no persistence” behavior of a cache is not strictly true: an unlogged table is only truncated if Postgre is shut down unexpectedly (by kill -9 the process or by killing the VM). If you restart if you shut down the process in a controlled manner, the unlogged table is properly persisted and still has data when it starts.

I have used Kotlin a bit for a hobby project and it felt like they were 95% done with a 1.0 version. I love the promise of a single code base that can run on the JVM and browser, but it is not all there. Until recently, the API was not guaranteed to be stable. Every one in a while, I hit a feature that is JVM only or does work right in JavaScript. The JS compiler will “helpfully” remove uncalled public functions unless you explicitly mark them with JsExport.

Also, from what I can tell, only InteliJ is the only supported IDE (which makes sense, since they are the language developers). There is an official Eclipse Plugin, but the last time I tried it, it did not work and tried to take the entire IDE down with it.

Having said that, it was very close to complete and I have not worked on that project for a few months, so it could all be perfect now.
