Failed project: The Daily Wordpress Reference[1]

I wanted to give an easy way for people to learn the intimidating WordPress API[2], bit by bit, every morning, in their email.

It failed because monetization was an afterthought. Even though it gathered a steady 1100 subscribers (daily emails) at the end (for about 6 months), I was unable to make a buck with ads (Amazon books related to wordpress).

Now I'm on my way for another failure with my online course on WordPress plugin development[3]. This one, I think I failed because I'm not a public figure in WP development so it's harder for people to trust me, and (related reason) I don't have much reach on social networks.

The author doesn't have the vocabulary for it, but what they're explaining is the difference between complicated problems and complex problems. The existing education system trains software engineers to solve complicated problems, those are what the author calls "hard problems". What he misses is that the problems he's talking about end up being challenging because they're complex.

I wonder if that's more or less how the video on demand worked in hotels in the late 90s?
If you are referring to a car wash, well the problem there is that car washes recycle their water. They filter out the dirt, but not the salt. So the salt water gets pressure fed into crack and crevices making things worse.
Huh? Where did anyone say anything about companies getting big? At this case you're just making strawman arguments.

What I (and I think others) are against is anti-competitive behavior. I don't trust the government a whole lot (even my party) but I trust it more than I would a company behaving monopolistically.
Summary quote (trimmed for brevity):

"The year 1816 is known as the Year Without a Summer... because of severe climate abnormalities that caused average global temperatures to decrease... Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora..."
Related question: Are there places recently that have gone a year without winter, due to climate change?
I really love that the Pascal/Modula/Oberon lineage became mainstream via Go.
The parent implied that in exception based languages you can save all the boilerplate since exceptions just propagate. My statement here was that I don’t think this is true, since you still need to do error handling (and have error awareness), eg for resource cleanup during those.

I am very aware about try with resources. It works however only if the lifetime of objects are tied to a scope.
I'm scratching my head to think of anything really significant. It's a bit of a stagnant period, albeit with lots and lots of churn, but all that churn hasn't really amounted to much.
For years I’ve (often unsuccessfully) tried to pitch people Metroid Prime, calling it ‘Myst with a gun’, to which my friends responses often include ‘what’s Myst?’.

The ones at 158k and 355k were the 12v battery. Those are annoying, but probably not exceptionally high for 400k miles.

It looks like 317,037 was the only high voltage battery replacement. That wouldn't be too bad, IMO.
I used it a few times before but I stopped once I realized it was a long way off from being worth using.

The lack of tooling, libraries, and numerous compiler bugs meant that it would be easier for me to write the same thing in C++ even though nim is a superior language.

I'd imagine many people came to realize this before even trying it out.

I’d say Unity is a free, fairly simple entry-level tool for this kind of thing.

Especially in combination with the Asset Store, which has a lot of free assets, and Fuse/Mixamo, you can pull stuff together with very little programming knowledge and share it to most major platforms.

I really love it.
The free batteries really must've skewed the data, assuming a regular consumer couldn't work out the same deal. Batteries are supposed to be a significant fraction of the cost of an electric car; analogous to replacing the engine in a combustion car.
It doesn't?

Also, there is no point where a Tesla will cross over to being more economical per mile driven with gas prices this low.
100km/h ~ 30m/s

3cm^3/s / 30m/s = 3cm^3/s / 3000cm/s = 0.001 cm^2 = 0.1mm^2

Fuel efficiency can be measured as an area, and 0.1mm^2 corresponds to approximately 30mpg. See https://news.ycombinator.com/item?id=9504215

edit: lol as i predicted. no responses just downvotes. is r/fragilehner a subreddit?

I'll surely get sure get downvoted but these kinds of paeans are so self-indulgent: smart privileged person (usually elite educated white guy) decides to pontificate on what makes for a gratifying life, what's important, what's valuable (or whatever other good mouth feel word they've chosen to use for their self-aggrandizing that day). and then follows a list of all of their accomplishments that aren't sufficient anymore according to their new measure. but of course now they're working on some nonsense startup that is sufficient.

What kind of echo chamber of privilege is hn where this kind of advice passes for insightful? It's basically like this: guys if you have a million dollars you shouldn't spend it on ABC you should spend it on XYZ.

Well I've got news for you: most people don't have a choice about what they do so whether they want hard problems or not is completely moot. They do the job that pays them to eat and have shelter and build a family. And yes I'm talking even about software engineers.

You should instead be writing about how grateful you are that you've had all the opportunity you've had and how you're actively working to empower others to have just as much (and not with some bs startup that extracts value).
Short answer: yes.

Long answer is that they don't do the same thing. I think jQuery was an incredibly clever and durable library and became so ubiquitous that most of it's most valuable features got folded into the JavaScript and CSS standards and no longer require dependency on a library. React is a modern way of structuring components. It's a fresh learning curve, but it's actually pretty intuitive and very useful.

It’s much, much deadlier and more likely to put you in the hospital than the flu, though. The trite comparisons to the flu are honestly irresponsible at this point. There’s a reason public health officials all over the world are taking this very seriously.
>React has essentially won the mindshare

Casually job hunting right now, and it is insane how much React has won to me. Like I knew it was popular, but it seems like it has an outright monopoly with the remaining 5% of market share being split among all the other alternatives.

I don't know what the actual market shares are, but when looking at open positions around the US from coast to coast, it seems to have won.

Ask HN: How To Reach Startups?
I've been running my own apps for 10 years. Recently I realized that I am under utilizing my vendors' capacity and that I could re-sell their services at the same great wholesale price I get. I want to offer an API to other companies so they can take advantage of my pricing and extra capacity I cannot fill with my own business. I believe startups would be ideal customers because I could beta test my API and grow with them without immediately overwhelming my system. How do I pitch my API directly to promising startups at ycombinator all the way from the Midwest?
I think DevOps and cloud services have had the most movement. Kubernetes is seeing rapid adoption as is TerraForm. I'm also seeing a bit of whiplash where enterprises are getting pretty comfortable going all-in on their preferred cloud vendor and just diving into proprietary fully-managed services. AWS is still tops, but Azure is making huge inroads.

Also, everyone has given up on chatbots. Voice assistants are increasing in penetration, but they're just defaulting to transactional modes and not conversational.

No. Not if you’re using a car normally. Water and salt will both cause corrosion and the longer salty water is in contact with the underbody of the car the faster corrosion will work. Even if you washed the underside of your car every evening after returning from work there would still be the corrosion from the eight or so hours since you left for work in the morning and that would accumulate.
My favorite unexpected consequence:

9. THE ERUPTION MAY HAVE LED TO MORMONISM.

One of the more unusual effects of the temporary climate change brought about by Mount Tambora’s eruption is that it may have indirectly led to the creation of the Mormon religion. Mormon founder Joseph Smith’s family was one of thousands that left Vermont during the freakishly cold summer of 1816. The Smith family subsequently settled in New York, where a teenage Joseph would go on to experience the events that led to his publication of the Book of Mormon. https://www.mentalfloss.com/article/73585/15-facts-about-yea...
> to be precise, I calculated the mel-cepstrum and fed it to the network

The mel scale cepstrum is inappropriate for pitch detection. You want to use the cepstrum without scaling frequencies. Take the fourier transform, normalize, take logarithms[+], then (inverse) fourier transform in the frequency domain.

The advantage of using the cepstrum for pitch detection is that most signals you're looking at will be harmonic — equally spaced overtones — and so when you take a fourier transform in the frequency domain you'll get a peak corresponding to that equal spacing, which will provide you with the fundamental frequency. (Even if it's missing!)

Using the mel scale totally wrecks that periodicity and throws away the pitch information. (Which is part of why it's used for speech-to-text! In those cases you want to throw away pitch information. Unless you're processing a tonal language, in which case probably don't use the mel scale.)

[+] Why logarithms? In the frequency domain, most harmonic sounds look like the product of a high frequency periodic "signal" (the fundamental and its overtones) with a slowly varying signal (frequencies which are emphasized or de-emphasized, like e.g. formants in the case of speech). Taking the logarithm splits that into the sum of a high frequency signal (overtones) and a low frequency signal (formants), and since the fourier transform is linear, that'll show up as a single peak in the cepstrum corresponding to the gap in overtones (ie the fundamental) and some stuff in the low-frequency bins corresponding to the formants.
I think it's important to include the general area because people commonly live and commute anywhere within a few miles. Most Americans live in what are technically suburbs.

And the overall lifestyle of a place depends on the population within a reasonable radius of travel, not what is within an arbitrary boundary.

I live in an area of NY currently that has towns similar in size to where I went to school in AZ, but the surrounding area, say a ten mile radius, has maybe three times the population. It's a very noticeable difference, both in general lifestyle and in employment opportunities, education and so on.

Long ago, we brought in a consultant to tell us why we couldn't max out our very fancy Oracle 9i database hardware. Nothing we did could get us much above 50% saturation on the disk array, CPU, or networking. We were stumped.

I don't know where Oracle is on this issue these days, but in that version there was a query cache for solved queries. And for a query to execute, it had to be in that cache. That dictated how many queries could be in-flight at once. Or rather, how many unique queries. If you used Prepared Statements, it would be happy to run as many configurations in parallel as you wanted. We were using Prepared Statements, so that shouldn't have been a problem. Right? ... Right?

And then he showed me the log of queries.

Less than 2 years earlier (oh, you can already tell this is going somewhere, can't you), a newer team mate was trying to scrub all of the query string arithmetic from our code. Someone had settled on some sort of Builder pattern, but this guy was getting stuck. The guy who had instigated this had to tag out for reasons that I cannot recall, so he asked me to sub in. I got a little briefing, then we went through the problems and I sorted him out, and then I very carefully explained to him what we expected of this code.

If you're gonna bind variables, bind all of them. Solving part of a combinatorics problem isn't solving it, solving part of a SQL injection problem isn't solving it. Bind. Every. Variable. Got it? Got it. You good? I'm good.

And then, dear friends, I made a fateful mistake: I went back to my other tasks and fires, and the other engineer oversaw the rest of the work and the code review.

18+ months later, I'm staring at a bunch of nearly identical queries in the Oracle query cache that have half a dozen bind variables and then a couple of distinct AND clause near the end. Plot twist: he was now my boss. The answer to 'why is our fancy hardware slow?' was, "because of you, Mike, because of you." Fuck a duck.

I guess maybe the reason he was so awful at giving orders is that he never learned how to follow them.
It is just an infrastructure investment. It's no different from Amazon building a local distribution center in your city.

An "internet fast lane" would be like the city government saying to Amazon, "and also, all traffic lights will immediately switch to green for amazon delivery vehicles."

No, they're still using the same roads as everyone else, they're just starting from a lot closer to the destination.
Does anyone care about some white dude talking about how lucky and privileged he is?

No.

It is interesting to hear that even the smartest people struggle with what to do. That’s helpful to other people who do have some privilege yet aren’t as fulfilled as they “should be”.
I have a simple solution that seems to work very well for me. If there are negative reviews I usually try to read a few to see if there is a red flag. For the positive reviews I check the dates distribution. Many products have only 5 star reviews but when you check you see they are all from the last two months. If I don't see old positive reviews then I skip the item unless it's a brand I'm familiar with. Finally, if everything looks good I check the seller(s) rating. Then buy from the best one. (For 3rd party sellers)

The idea is that it's hard to keep a fake high rated reviews for a long time.
I see a lot of downvotes, but no coherent answers. Seems like I hit a nerve.
I do not necessarily care about hard problems, but I do care a lot about interesting work. Fighting fraud sounds interesting, learning accounting sounds interesting. I find interesting for me often correlates to things I don't know. It is hard to get hired on things I don't know and even harder to stay at the job once I've figure the things out. Happy with my current role because I'm working on stuff that I have to figure out.

So I think less so hard problems and more so learning opportunities.
Lots of biomimetic optimization algorithms like Ant Colony Optimization do this. Maybe adding some randomness in the hiring process would be a good thing?
I gave up 1/2 way through because the photos were too small and low quality to even attempt a determination. Worthy topic, poor exploration.
I haven't read the linked paper yet, but the blog post points a little to what's on my mind.

To borrow a bit from a different paper and anonymous reviewer on one of my papers, inference serves different aims or philosophies. Sometimes it serves more of an estimation function, to increase information about some quantity, or to improve the estimate of that quantity. But sometimes it serves an evaluative, competitive function, in the Popperian sense of affording risky tests of one or more theories or models.

In this latter Popperian aim of inference, priors are to be minimized, which is in many ways the opposite scenario that is assumed with standard subjective Bayesian methods. And even with the former "estimation" inferential aims, there may be situations where you truly have no information or don't feel comfortable assuming it.

What's nice about Bayesian statistics is it still provides a framework for this scenario, in the form of reference priors, in that if nothing else your design and model supporting the parameter(s) to be inferred about implies some kind of assumptions about what you're making inferences about. That in turn can be transformed into a "least informative" prior. So it allows an objective Bayesian framework.

However, in that framework, in many cases you're still often left with uniform priors, which then reduce to frequentist statistics. And in a broader sense, frequentist methods are even further removed from making assumptions in that they completely eliminate the prior from inferential consideration.

There's a tension then, in that in small samples your priors will bias your estimates. If you use least informative priors, you're often doing something akin to frequentist methods anyway. And in large samples the likelihood dominates the posterior so it matters still less.

From a certain perspective, ultimately with Bayesian methods you're making a bet that your priors are accurate enough that the increased bias in estimates will be small enough to be offset by decreased variance due to use of a prior. It's a gamble though, the risks of which will probably vary depending on the costs and benefits of different types of error.

It's nice to see a paper trying to be honest about the problems with Bayesian inference, as it's a bit overhyped at the moment imho.
Their in-store pickup is very convenient. And their prices are pretty good. I'm avoiding buying anything from Amazon since August because of the numerous problems I was having with them. I did have to buy one technical book about database design from them because I couldn't find what I was looking for anywhere else. Otherwise it's been really painless not using Amazon for any purchases.
Are these legit sites / apps you are reading? How are you finding them? Another approach might be to reach out to the ad network to complain about these illegal ads. (Fake paid reviews are illegal ads, and soliciting illegal activity is illegal.)

The solution here is probably to convince authorities to prosecute the individuals are accepting bribes for fake reviews. Amazon should be happy to cooperate.
I was more thinking about a dedicated procedure, optimized for salt removal.
I felt that way for about 10 minutes, after which it felt like visiting a Hollywood set; looks great but it's just a facade. The level of interactivity was just too little to be convincing.

As TFA says, a lot of people blame Myst for the death of the adventure game, but it was already trending that way in '93 as graphics improved. Most of the random actions that you could take to interact with the world in the Sierra games resulted in a fairly generic animation and a wall of text. This meant anything the designer anticipated could be interacted with, because the cost of writing that text was low (particularly with Sierra's near lack of editing and playtesting).

Once a generic animation and a wall of text was no longer acceptable from a production-value stance, these games were stripped of their charm, and all you were left with were charmless puzzle games with some window-dressing. Myst got there first and did it better than everyone else, so it gets the blame for something that was inevitable.
Good ol Google being the opposite of what got them where they are currently.
It is not particularly ironic; there's no actual design here. It's easy to say that a feature should exist (and your parent has said this, about this, repeatedly) but it's much harder to make sure that it's something that has the correct semantics (and your parent has never actually produced this, even though they've been asked, repeatedly.).

Oh, that’s neat. What is this script called? How do you run it?
The past few days I tried putting a personal project with Docker containers together consisting of nginx, certbot, static frontend files (built from source), backend web server. My goal was to be able to call docker-compose up. I’ve done a similar project before without Docker so I know what the end result should look like. Integrating the Docker containers with each other and getting the configurations right is a nightmare. Today I realized I can’t justify the time spent as “learning experience” anymore. What I did was premature optimization that failed terribly and cost me days.
