Aside from generating revenue for what are surely wasted impressions, why does the online ad industry constantly show users web ads for things they've already purchased?

Does this not represent conspicuously wasted spend on the part of these advertisers? It's been going on since the DoubleClick days and never ends. How can this industry bill clients with a straight face when their display decisions are made this crudely?
The issue I suspect caused this is all of the newer energy efficient washers/ dryers. The author tested a Samsung dryer. I recently lived in apartment with a similar model, and it was terrible. When visiting parents I was stunned at how well their older washer/dryer worked. The clothes came out much more clean too.

In my experience the newer energy efficent washers/dryers are almost total garbage compared to the older ones. I would love to see this experiment repeated with an older 90's kenmore or whirlpool or really any brand from the 90's or before.

I love the idea of saving energy, and energy efficient laundry sounds like a great idea on the surface, but what I think happened was the government put regulations in place without really considering the actual impact this would have on the quality of the washers/dryers.
It seems pretty likely to me that Steve Jobs was a high functioning sociopath. The line about how his demeanor changed dramatically when Carmack's wife asked for a favor was indicative to me.

"One time, my wife, then fiancée, and I were meeting with Steve at Apple, and he wanted me to do a keynote that happened to be scheduled on the same day as our wedding. With a big smile and full of charm, he suggested that we postpone it. We declined, but he kept pressing. Eventually my wife countered with a suggestion that if he really wanted “her” John so much, he should loan John Lassiter to her media company for a day of consulting. Steve went from full charm to ice cold really damn quick. I didn’t do that keynote."

I find sociopaths fascinating, but I would sure never want to work for one. It must take an incredible amount of calculation and self discipline to keep a semblance of normality for an incredibly high profile sociopath like Jobs.

On a side note, the late Pieter Hintjens of ZeroMQ wrote an excellent book about psychopaths available online for free here.

Also want to disclaim that I am not a psychiatrist and my opinion of Job's sociopathy is only my speculation.

An alternative explanation could be that Apple is quietly discontinuing MacOS laptop / desktop computers while putting more resources into replacing them with larger iOS devices. At some point it no longer makes sense to maintain separate operating systems and hardware architectures. All the pundits have been predicting convergence for years now.
* Orchestrated, in-house built workflow execution engine.

* Message queue based with service listeners that translate and dispatch messages to individual workers via HTTP requests.

* Workflow execution state is currently backed by RDBMS.

* Infrastructure errors with workflow executions are exceedingly rare and devops can push a button to retry a step if they failed due to a transient condition.

Now, the important bit:

* Retries due to business logic error aren't really a thing unless there is a defined recovery transition for that step in the workflow. This forces people to acknowledge their code did something unexpected (or the workflow definition itself doesn't properly handle all necessary error cases) and fix the underlying issue. Once the root cause is identified and fixed, the workflow instance can be canceled and resubmitted. However, since things that do work usually have side effects, there is sometimes manual cleanup that has to occur that falls on the development team to fix (with assistance from the devops team, if needed). No one likes doing cleanups or getting on devops bad side so there is an incentive to make sure code and workflows are well tested before being released to production.
You mean like Yahoo?
To my knowledge, yes. Whenever I’ve had Comcast, Verizon, or another provider pull a last mile of fiber, it’s been done by a local contractor (my experience is limited to Illinois, Florida, Indiana, and Wisconsin) with the upstream provider coordinating the turnup.
Washing machines use cold water and heat it up themselves, so I don't see the connection?
Are you sure that you aren't confusing force with energy? Angular or not, it's just accelerated mass.
> potential energy

There isn't really such a thing. It's just a matter of your viewpoint if something is potential energy or actual energy.

Physically they work the same (for example both types of energy gravitate, and contribute to mass).

The problem with Jabber is, that you are locked in to one server, switching means that you have to re-add all your contacts and so far there is no automatic way to do it. I think the developer of IMCom (console Jabber client) thought about that and how it could work but I don't think his idea got a lot of attention.
So that kills a lot of the point of the app?
Definitely in the cards. Would take a while though.

Faculty interview questions I asked and got asked
My experience... while Lambda is capable of hosting micro-services, any coding pipeline that emphasizes continuous integration (CI) will be better served with one, generic, monolithic Lambda function that dispatches to sub-modules behind the scenes.

However, this only scales up to a 50MB binary distributable.
Chasing pointers is cache death. Many theoretically optimal algorithms have been struck down by the God of Memory Latency.

eg, If you measure it, tree performance will often be much improved by storing slightly less than one cache line's worth of data at each node. The CPU can pipeline and predict the shit out of the linear search at each node to the point that all the theoretical O(1) or O(log N) lookups in the world get demolished by a CS101 scan of the array. This makes a relatively good general use cache aware data structure because small collections tend to fit into a single cache line while large data structures have relatively few pointers to chase.

Of course as the OP demonstrates, optimizing for your specific use case can yield even more dramatic improvements.

Api Store good or bad idea?
Hi, i would like to ask you, what do you think about my idea. Basically i am thinking about something like AppStore but for API's. Idea is that you can add your service to the platform and set price for access to your API (which can do basically anything). It can be monthly quota or pay per use. Platform will handle charging users and will make money on commissions. You as an API provider don't need to set up company, handle user registration, taxes etc. Would you find this kind of service useful?
In addition to the info above, there's something quite sinister about the "bio ceramic" products tap into human psyche.

The first time you use these products, they appear to work--your clothes actually get pretty clean.

This is because your clothes still have enough embedded detergent in them to still be effective.

After a few washes, the detergent is all gone, and your clothes stop getting clean. But you've seen the product "work", and it's hard to change your mind. Eventually you give up but it's been so long that you don't return the product.
> They just break if anything goes wrong, not rolling anywhere.

I saw a video of a flywheel being deliberately destruction tested. "just break" is putting it mildly - it looked like an explosion, and left white-hot pieces of the flywheel behind.
Olbers' paradox – The night should be bright
> But the 68% increase from 2002 to 2015 in the incel share of the male, never-married, 22-35-year-old population is mostly due to a decline in marriage, not never-married men having less sex.

The authors of this article admit that involuntary celibacy is rising among young men. They admit that 20% of the men are having 60% of the sex while incels claim it's 80%--not that much of a difference. Marriage is declining--and that's their coup de grâce? Gimme a break. The decline in marriage could be due to all the factors that incels claim: that people, including women, are more promiscuous outside of marriage and that social media and online dating make women more shallow and appearance-oriented.

While there are some problematic, misogynist aspects to the incel and MGTOW (men going their own way) movement, this article does nothing to shed light on the existing problem of young men feeling increasingly isolated, anti-social and cut off from the sexual marketplace. Incels are consistently written off as simply misogynist while the numbers clearly point to a more endemic problem that no one will address because young men are not considered an oppressed group.
The thing to be skeptical about is the notion that it is possible, or even desirable, to reflexively sterilize and sanitize everything in sight.
It's worth remembering the other people involved in this. Peierls and Frisch worked under Oliphant at the University of Birmingham, and they wrote the memorandum which formed a major part of the Tizard Mission to the US. This also included the much better design for the Cavity Magnetron, also developed in Birmingham by Randall and Boot, who also worked for Oliphant.

In 1943 a British delegation led by James Chadwick (who discovered the neutron and won the 1935 Nobel Prize) went to work on the Manhattan Project, and included Oliphant, Peierls and Frisch, as well as Klaus Fuchs (who it turned out was a Soviet spy) and Tony Skyrme (more famous for his work on what later became known as 'skyrmions'), all from Birmingham, the Danish Physicist Neils Bohr (Nobel Prize winner in 1922) and Lord Cherwell who had invited Bohr to England and who was an advisor to Churchill and who advocated area bombings of Germany. The British techological 'Tube Alloys' programme was absorbed into the Manhattan project.

Bohr advocated sharing the technological developments with the Russians, and met both Churchill and Roosevelt in attempts to try and convince them of this. The British mission basically left with the passing of the Atomic Energy Act 1946 which prohibited the sharing of nuclear secrets with allies by the US government. It wasn't until a few years after the British developed their own nuclear warheads (the first being the Blue Danube) that cooperation on nuclear warhead technology began again in 1958.
I would also be unwieldly verbose, and break backward compatibility.

The Newspeak, as a fictional language and thought exercise, takes a phenomenon that occurs naturally in real life and proposes a way to exploit it. The "incel" label is just a natural, real-life occurrence of the phenomenon Orwell noticed and described.

Except for the fact that you can conceal the source of the cryptocurrency asset, then the recipient can exchange it for clean money. That's textbook money laundering. Can you tell me how much of Wikileaks' donations come straight from international organized crime? No, and I can't either.
Detergent is a surfactant, designed to lift dirt, food and other stains from your clothing to be rinsed away with the water. It does absolutely nothing in terms of bacteria or germs beyond this.

In cases where that's necessary, like hospital linens, a combination of bleach and hot water is used. Most new washing machines now come with a "sanitize" setting that will use a built-in water heater to get to boiling temperatures to clean clothes.

You should also clean your washing machine regularly, using empty cycles and letting it completely dry out. You can't clean much if the cleaning equipment itself is dirty.
Yes, and I was alluding to mentally specifically, wasn't I?
Just a comment on branding.

I worked for RealNetworks a long, long time ago and I remember when we came out with RealPlayer One in 2002. This was an effort to bring a bunch of products together in the face of competition from MS and others. The vision and company failed spectacularly.

The "One" branding strategy strikes me as a way to bring together disparate offerings that people can't articulate easily to users and probably shouldn't be bundled together. Maybe Google is about to do the same:

"Google One’s director Larissa Fontaine told me that those could include discounts on hotels you find in Google Search, preferred rates for other Google services or credits on Google Play".
yes, I was wondering the same... that should be enough.

Ask yourself honestly: Do I really need sex/intimacy or is it just a bonus at best? Take a coin, label one side as never have sex, the other as have sex, flip it and observe your feelings once you see the result - did you feel relief or stress? Then you know "the direction of your heart". If you want to start meeting lots of women, buy a camera, spend a few months mastering the art of strobe photography to get at least to average level, make a profile on Model Mayhem, start doing castings or respond to traveling models in your area; if your work is any good, within another 6 months you'll be meeting the most beautiful women on this planet, possibly most entitled as well ;-) You will definitely have no issues talking to any woman afterwards, probably you'd not even want to approach most women and reject them outright if they ever approach you. If you get yourself in shape instead of being lazy or busy etc., that would also help tremendously. If Flavio Briatore with his physique could date Heidi Klum, what are the limits for ugly incels? It's all in your head, possibly in hygiene and how you dress as well. Don't be stupid, anyone can do it, women react to completely different stimuli than you were taught; once you figure it out you'll be laughing on how silly you were.

There was a fascinating podcast on RadioLab about the intelligence of trees and one of our writers wrote about it (this is a Christian publication about weird stuff): https://gospel.vision/discovering-the-mystical-intelligence-...

I've started talking to trees since discovering this.
The insecurity of many of the popular package managers (pypi, npm, crates) and the wholesale reliance of so many software systems on these managers seems like a massive security risk. While I appreciate the simplicity of getting an up to date environment through these managers, I always have a tinge of fear in using them. Whether it is backdoors, information theft (like this article), or filesystem destruction, they all are simple to implement and simple to hide. I let so much arbitrary code run on my computer when I import a python module. Maybe the breach isn't in a popular top-level library, but some dumb little dependency. It's even more dangerous because most eyes aren't looking at that dependency, presumably.

I am tremendously naive to infosec and security in general, but I can predict that the big companies have measures in place to mitigate these risks. Containerization seems like it could help limit the scope of the damage, but the popular containers seem like they are more at risk (usually downloading the latest releases) to encounter these attacks.

What is the likelihood that some actors (state-sponsored or otherwise) could bring down some major systems? Not Google/Facebook/Visa/Netflix major, but widespread across many smaller platforms.

Blackhats and Whitehats out there must be collecting information on:

Which dependencies/libraries could be targeted

Which authors/publishers are vulnerable (regarding password safety, lib deployment mechanisms, ...)

Which systems/libs to compromise to affect classes of targets

I feel like this is a likely cyber attack vector over the next 10 years. How haven't there been more of these that are successful? Is someone building the intelligence in preparation for attacking? Are these systems actually secure (if you successfully avoid maliceful users)?
Clearly not all of them do :-) But curious as to the relative ratio I discover that best buy has a separate listing for machines that include an internal water heater. According to their web site, of the models that Best buy sells the population is about 40% (54 models with internal water heaters over a population of 138 models)
I respectfully disagree. I could regurgitate the content on the website but that would hardly be any more substantive. Often these threads lead to curious people asking questions about Mastodon, and I'm happy to answer them and engage in more discussion.
Only very specific models of washers in the US actually heat up the water. Most just use water from the water heater.
I'll be honest, you come across as a bit of a curmudgeon, but you're totally right! In a fraction of the time it took them to write an article, and a response to the responses to that article, they could have just emailed a better wording and fixed the problem!
The latest Argo release (https://github.com/argoproj/argo/releases) supports resubmitting workflows with "memoized" steps.
> That it might be inefficient in practice

That's basically it.

Consider that his algorithm completes 16-searches in 20-cycles, or roughly 5 nanoseconds.

A single fetch from main-memory will take 50-nanoseconds, or be ~10x slower than the methodology discussed in this post. Even a fetch from L3 cache is typically 10-nanoseconds, while a fetch from L1 cache is 1ns or ~4-cycles. This SIMD-methodology is incredibly FAST.

The "best-case" scenario of this SIMD code is 6-cycles, which is faster than two L1 fetches. (!!!)

Note: two L1 fetches would likely go into the reorder buffer and be out-of-ordered into an efficient manner. But... ignore that plz since that destroys the point I'm trying to make. Lol. Still, you can see how repeatedly forcing even L1 fetches would slow down the code, and "pointer chasing" is more likely to fill up the Reorder buffers, since you cannot rely upon prefetchers to pre-fetch the data, or other such tricks of the CPU.

Algorithmic complexity means that eventually, the linear / SIMD methodology eventually will be slower with a big-enough dataset. But when looking at small data-sets and optimizing them to the maximum ability (ie: searching 16-strings ASAP), linear / sequential scans are king. Kinda like why insertion sort ends up winning in a lot of small cases over other sorts. CPUs and RAM are incredibly well optimized for sequential data scans.
Growing up in Korea, and living in the US for 5+ years now, what I've heard is that American washer models are so forceful that they wear clothes out. If you are accustomed to such washers (and clothes made with such expectation) I can see how you think the newer models are not as good. But I would choose a Samsung/LG washer over Whirlpool any day, if the prices were the same.
The article claims "The Crystal wash did not seem to do BETTER or WORSE than regular detergent", but I'm really curious to know how the author was scoring that. At least to my eye, the density of bacterial colonies in the "Crystal Wash" sample looks much more comparable to the density in the "no detergent" sample than to the "Kirkland detergent" sample. But maybe it falls under her threshold of statistical significance.

Even apart from the results of this experiment, the basic concept of this product sounds really sketchy to me. I'm not going to say that there's no way at all that mere exposure to sunlight could recharge a catalyst that would change the pH when immersed in water, but just about every pH changing process that I know of involves using up some chemical reagent, and exposure to sunlight alone seems unlikely to replenish that sort of resource. So it sounds like snake oil to me.
Azkaban really seems to strike the right balance between simplicity and featurefulness, I'll definitely give it a try! Plus it seems relatively simple to deploy & maintain.

The documentation often mention Hadoop and data jobs, have you also used it for non-data things? Would you by chance have some workflows examples?
Everyone? How so?
Exactly. That's exactly what disappointed me about Narnia: I felt like Lewis is ramming his Christianity down my throat, whereas I never felt that way with Tolkien's work. Whenever I compare Narnia and Middle Earth and people tell me "but Tolkien's work is also allegorical", my reply is "If the word allegory can be applied to both, then we need to split it up into two different words, to distinguish two things that are obviously different."
If you reached a point where you need to require bash and not a posix shell and need to enforce these rules just use python or lua if you can or some scheme or whatever else... it's not worth the wasted time hunting bash cruft.

if you are on busybox with ash none of this is helping (except shellcheck which is great).
Why is anything you just asserted any more valid than someone claiming that being a jerk is useful trait in becoming successful in business? Just because you used 'orthogonal' in a fun context doesn't mean you've given evidence that your assertion is valid.
> might be set to 60C (130F)

Don't do that. You risk legionnaires disease. Set the temperature to at least 140F.
in itself pointer chasing does not mean misusing CPU caches (your dataset could fit in cache and you could be pointer chasing inside it).

the main issue that is strictly due to pointer chasing is that you risk having long dependency chains in your instruction stream (address of the load depends on the result of the previous load, the address of which depends on the result of ...).

This is pretty bad for a modern CPU since a lot of the speed comes from overlapping independent computations.
Maybe the Google experts are actually Duplex bots.
And this does not refute the argument of incels; it supports it. The idea is that with a higher percentage of the population getting married, the average man was more likely to find a partner. Without monogamy, the number of sexual partners skews heavily toward the top 20% of men, leaving less sexual partners for less attractive men.
