I lose things extremely rarely so much so that I distinctly remember the only two things I've lost in the last 5 years or more. My rule is simple: put the item back to its designated place the moment you are done with it.

One of those two things are the faucet o-rings that I've placed somewhere near the faucet itself thinking that "it should be easy to find them here", rather than putting them in my usual tool bag. They are still "missing" to this day. I will probably find them when we move.

It is my policy these days to investigate how easy it is to cancel/delete a service or subscription before I register for it, which is incidentally why I will never ever be a Comcast customer.

Until recently I would get spam text messages from my own cell phone number. Telecommunication companies are complicit in all of this for allowing phone number spoofing. As long as they make money I guess it's OK for them.

... and another beauty of a math book written in LaTeX is that you can fit a 286-page book into just 1.3 MB. Good luck doing that in MS Word.

Without the societal/technological contributions of the so-called introverts, the extroverts would still be writing paper letters instead of being able to bully each other from the convenience of their mobile phones. These borderline narcissistic people are exhausting...

This article is such a weird flex. Who cares about what kind of fancy mouse someone uses.

What makes Raspberry Pis competitive is not necessarily hardware; it is software. I guarantee this is not going to be a serious competitor to Raspberry Pi, at least not for the intended audience of Raspberry Pis.

Is pair programming still a thing? I can't imagine putting myself through such a dreadful experience.

I wish there was HN gold or something like reddit so that I could give it to you.

As a PSA for anybody who wants a very readable introduction to "real" math, check out Jay Cummings' two books: Proofs and Real Analysis at https://longformmath.com/

Each paperback book costs less than $20 on Amazon.

Not the OP. I find the clasic Time Series Analysis book of Box & Jenkins to be a good starting point for "basic" time series forecasting. And even that book is a difficult read: pleasant book but the theory and concepts are still hard. A deep understanding of stationary signals is a must for time series forecasting which is pretty hard to grok in my limited experience.

But, in a way, OO modeling and design was invented to solve the mess that "banging out" procedural code created in the first place.

You have to model your business domain in software one way or another anyway. Why should it be bad to try to be more methodical about it using OO methods? We do it with relational databases all the time where tables are pretty similar to objects.

Sure, you can certainly do research outside of academia. But, for all practical purposes, you cannot publish at a reputable journal without an academic or R&D center affiliation.

However, what you call "nitty gritty of writing essays" is there for a reason: to streamline the communication and acknowledge the contributions of others. As long as you are not inventing something unseen before, you just cannot "do research" without also doing those things.

I looked at some tutorials and videos, but I can't seem to be able to create a smooth stream no matter what I try: different frame rates, different resolutions, etc. RTSP streaming works reliably for me, but the stream is always choppy. Have you had a better experience?

Regardless of what anybody says to the contrary, story points are and have always been used as an obfuscated measure of time. When we can never estimate plan timelines correctly in the first place, why would anybody think that we should be able to measure story points with any accuracy? It is just another stupid PM gimmick to create useless management metrics.

With my limited knowledge of network technologies, I still found it relatively easy to setup a Pi Zero + Raspberry Pi Camera Module system to stream video over RTSP to VLC software on my desktop or phone. The stream quality is pretty crappy, but I am hoping that, at least, this would not send my video to some Chinese servers. Anybody else experimented with such setup?

Just today a friend who sold their house couple weeks ago told me this: they had an internet-connected Wi-Fi lawn irrigation system. After selling their house, they had their internet service cancelled. Along with it the Wi-Fi system turned off of course. The irrigation system loosing the internet connection decided to turn on the irrigation with nobody able to turn it off as the new owners had not moved in yet. The lawn promptly flooded with water flowing to the street for two days straight. A worried neighbor called and the buyer's agent had to go to the house to manually turn off all water in the house. So much for smart IoT systems...

> It's stated several times on the sign up screen that it's auto-renewing.

Well, that's the problem. Why should the subscription to the app be auto-renewing? It is really for the business's convenience and bottom-line rather than the customer's.

Auto-renewing or not, I always get mad when money goes out of my bank account unexpectedly as I won't always remember when the auto-renewal is due.

> Not my fault if you fail to cancel.

This sums up nicely the attitude of predatory businesses. Why don't we remove auto-renewal and say, instead, "it is not my fault if you fail to send me a reminder to renew my service", if I still want to do so.

Somewhat besides the point of the article, but I would never but a Nissan car for the sole reason of what they did to the Israeli owner of nissan.com.

When I read the badly-written documentation (manuals, datasheets, etc.) of a lot of Chinese products like calipers, stepper motors, and ICs, I often say to myself that I could fix the language easily for a small fee and make their products more appealing when the actual product itself works pretty well.

I wish there was a simple way to monetize this by offering such improvements to companies without a race-to-the-bottom market place. Perhaps companies offering bounties for such suggestions for improvements?

As usual, "correlation is not causation".

I don't think ST's HAL is that good, but I agree that the software support from other vendors is much worse, which is why I actually prefer to use ST microcontrollers.

I wish microcontroller companies also realized this. The amount of shitty development software produced by the likes of ST and Atmel is mind boggling. You can get awesome microcontrollers with crazy capabilities but the software support (IDEs, compilers, HAL libraries, etc.) is invariably terrible. ST's HAL library is a good example: full of bugs, weird APIs, Eclipse-based IDEs, ...

> I mean, anybody can do research and publish their papers in whatever journal.

Not really true. Publishing research in a reputable journal without an academic affiliation is many times more difficult. Sure you don't need a PhD to publish, but you pretty much need an academic affiliation.

Good or bad, researchers without an affiliation are often taken as crackpots.

Yes, I would say it is still fairly easy to enter the software development field.

It is worth remembering that software development is a very broad field ranging from changing size and color of buttons on a webpage (which is perfectly fine) to sending rockets to space.

I don't know how true it is these days but people are/were able to find software jobs after a couple months of code camps.

I don't think we have a software crisis. Millions of programmers are able to create more or less useful programs all over the word; everything including your toaster is running software on it succesfully enough; and the community was able to build programs that are accessible to all from a 5 year old kid all the way to your grandparents. Where is the crisis in it?

However, we have a project management crisis, which is not only limited to software, where people in charge of planning are distanced from people in charge of the delivery. And we don't seem to be able to bridge the gap. Agile, Scrum, whatever are indicators of this gap where "gurus" take all of us as fools and we are not able to produce anything better ourselves.

Commoditization of software development is also contributing to this mess because people of all skill levels can find a way to partake in this activity with results of varying success. This is not good or bad, but just the nature of ease of entry into the field. Not much different than food business where we have both Michelin star restaurants as well as MacDonalds of the world both of which have consumers. But we don't say we have a restaurant crisis.

Kicad for electronic circuit design. Freecad for CAD and solid design.

Interesting. I've just implemented an algorithm (matrix profile) that makes use of FFT to compute a big set of dot products of time series subsequences where the length n of the time series can be in 100s of millions. The fast convolution computation using FFT reduces the computation time from O(n) to O(log n) with awesome speed gains at this scale. Throw in a GPU and the speed goes up even faster, like processing 10 million data point in 0.1 second on a laptop.

Call me old fashioned and simplistic: JS, HTML, CSS, NodeJS, pm2, nginx, AWS server, S3, github.
