Traffic cameras are publicly available in London. The first thing I used to do when coming to the office each morning was to look myself up in the traffic cameras along my journey (historic footage is also publicly available).

You Don't Need to Learn Vim
With one caveat: We can understand things without understanding them. You can understand the steps without understanding the why.

My favorite example:

https://www.smbc-comics.com/index.php?db=comics&id=1914

So a question can be "can we create a model we don't really understand?". For which the answer is partially yes, since nobody can visualize 4D, but we can math it.

But yes, maybe there are indivisible mental building blocks we can't even understand. Flatland comes to mind.
Pretty much just Java but a few more affordances for flat memory layouts. I know value types are in the works and the new memory api is in preview so we're getting there.

Oh, and I think every language should come with an AST parser in python. We need to really lower the barrier to manipulating codebases with code. And before any one mentions Lisp, we know — and we'll never learn. Blub blub blub.

I'd like to be able to @Annotate a class with @Localized and enforce just that it'll never get assigned to a field or passed to public functions — only local variables and private functions. For anything mutable, it'll buy you 80% of what a borrower checker would.
Sure, but how does this affect a browser that is not a product for sale?

A very interesting application of constraint programming is the Unison compiler https://unison-code.github.io/, which uses constraint models to solve compiler backend problems for llvm. As a simple example, register allocation can be modeled as a graph coloring problem for which there is an edge between every variable which must be live at the same time and colors represent registers, but he unison model is sophisticated beyond this. We use a simpler related model in our project VIBES https://github.com/draperlaboratory/VIBES which is a micropatching compiler (it uses the constraints to compile code in such a way it can fit in place, has the right stuff in the right registers, etc.)
Spend 2 days and write down everything you eat or drink in a spreadsheet with calorie count (including oil and condiments). Use a digital scale if possible for more accurate measurement. The answer will be glaringly obvious.

Most people don’t do this and spend their lives wondering why they can’t control their weight.

Some quick culprits: sodas and juices (huge amount of calories), excess oil in food cooking (oil has a ton of calories), side dishes and snacks (chips, French fries, crackers, etc.).

On the satiety level, if you eat out a lot or processed foods, most have little fiber and aren’t that satiating (e.g. you can eat a whole bag of chips or thing of crackers and want more). Either more fiber or protein.

Really the main solution is to limit eating out if you live in America. I eat out once a day maximum. Otherwise you’ll most likely hit a caloric surplus.
It is pretty much unparalleled in terms of the product of ecosystem size and performance. The other two languages in the top 3 are javascript and python, both have serious deficits regarding parallelism. As seen, it is a pretty strong contender in performance alone as well, with perhaps the best observability, and it has a well-defined execution semantics, even regarding erroneous execution — while any sort of memory error in a lower level language may silently corrupt the heap after which no assumption can hold regarding program state.

Also, primitive-only java programming is probably no worse than similarly low-level C/C++/etc.

>Mostly because they are not depending on work for their social life

I've heard this a lot. It seems a point of contention. I don't see how people don't depend on work for some level of social interaction. How can one want to spend 1/3 of their life not giving a fuck about the people they work with? How can someone want to sit at a computer banging out useless shit for faceless corporations and not have the conciliation of suffering through it with people you know and like?

At my last pre-covid job, once covid hit, my team of 10 or so would do voluntary virtual happy hour (VHH) and we would, for several months, be on zoom for hours and hours after work on Thursdays, drinking, playing music over Zoom, Among Us, and so on. And work was about 10x more enjoyable than whatever it is I do now, in large part due to that comradarie.

Even before that, part of the success of my job was through socialization. I don't mean climbing the ladder or kissing ass. I mean getting to know people on different teams through running into them, working in the same area, and spontaneously chatting about their work and how our teams affect each other. That kind of communication and collaboration is much more difficult to scaffold on Slack.

I know that a lot of movement into IT and within IT was through this kind of spontaneous meeting of people when walking through the halls or running into each other at the coffee shop. Work was a community of diverse roles and individuals, a microcosm of society where people could see how others work and be part of something bigger than our team. It sounds cliche, but that's how it felt.

Now, we have #team-chat and #diversity-and-inclusion and @manager.

TLDR: Social interaction at work is healthy; social interaction at work helps people enjoy work, learn about other roles and have job flexibility and helps them do their own job better; The thing you spend 1/3 of your life doing should have a human component.
Just in time for the winter.
PhD in math here...I disagree that it is just a tool. I don't really give two cents about the usefulness of math. I only studied it as an art because I appreciate its artistic beauty. For me, math is only interesting as an art, and practical problems aren't any motivation for me in that regard.

Hetzner announced 10% increases starting September https://docs.hetzner.com/general/others/price-adjustment/

From email to customers

"Energy prices from suppliers have risen drastically since the end of last year. This phenomenon is affecting people and industries across the globe. And since prices are not likely to drop or stabilize in the near future, we are forced to increase the prices of many of our products by approximately 10 %. In addition, we also unfortunately need to implement a serious increase to the electricity/air conditioning rate for our colocation products."
It's not 40% less gas. Europe managed to mostly fill their storage tanks over the summer, and Germany has 6 LNG terminals coming online in December. So it's going to be only 15% less gas. So no riots, no freezing to death.
Partially, those imaginary numbers offer ways to embed more geometric/topological reasoning into the number system than being imaginary. Like how adding the point at infinity makes the 2d plane more like a sphere.
Before getting too excited about the experimental prevention they used, IL-1B blockade, let me say that blocking the innate immune system to prevent cancer seems ill-advised. The innate immune system is with us for very good reasons. This would be roughly equivalent to preventing table saw accidents by prophylactically removing all fingers.

Yes, table saw accidents are terrible, but there is a straightforward electromechanical solution (SawStop), and fingers are useful for many other things.

Yes, lung cancer is terrible, but there is a straightforward electromechanical solution (energy from renewables + nuclear), and the innate immune system is useful for many other things.
Yeah heads up displays have to be at least an order of magnitude cheaper to produce, if not more.
Without remote work options tech is simply not a family friendly career. If you want more in life than the “opportunity to work in a fast paced environment”, rent a lousy miniature home or live with housemates then tech is not the right choice. Sure there are those who get paid a nifty compensation in return for their freedom, but thats not sustainable. Remote work on the other hand allows for proper personal growth. The higher the reward the better the motivation the more productive you are. A win win situation.
One fairly thorough answer:

https://www.republic.org.uk/a_new_head_of_state

> The kind of head of state we think is best for Britain is a 'ceremonial' or 'constitutional' position, someone chosen by the people to:

* represent the nation

* defend our democracy

* act as referee in the political process

* offer a non-political voice at times of crisis and celebration

> The job would not simply be ceremonial, our new head of state would have very clear and limited powers. Those powers would be non-political, which means that they can only be exercised according to certain official criteria. Our elected head of state would not be allowed to make decisions based on their own political opinions (much like a judge uses their power according to the law and the facts of the case, not letting their personal politics get in the way).
The Raspberry Pi Pico W might be an alternative these days. Of course with only a couple Cortex M0 cores and 264KB RAM running JavaScript would be less than feasible, but rendering a pure black and white framebuffer for a e-ink screen should work OK.
I believe what you're looking for is (in PostgreSQL) called a set returning function.
There would still need to be a commercially supported SaaS version for all I/T managers who won't buy a service that doesn't come with a "throat to choke" (other than their own) if things go wrong. That said, I hope Element/Matrix can have a corporate offering to be that thing.
But isn't that the point? If solar plants can be deployed quicker and cheaper, that is what should be done (and of course the same applies for wind generators).
What strikes me here is the willingness of the father to equip Feynman with the right tools and admit to his shortcomings. The 'practical man' series also sounds interesting. Is there an modern version of these books? Or do the originals stand the test of time?
The mall is perfectly suited to adapt to 2000 new residents; shift one store to a grocery, one to a daycare, and you're 90% of the way to rebuilding a nice little town center that lets people live most of their lives without a car.

The real problem is the planning profession, which has taken to such micromanagement of central planning that there's no way to dynamically adjust spaces to better uses. In my local downtown area, there are extremely strict rules about which type of retail are allowed where. And how close to which corners. It's a disaster.
Probably the idea is to somewhat sneak that in through the back door, i.e. hope that car manufacturers would be too embarrassed to advertise with a bad crash test result, even if the bad result was "only" due to lack of pedestrian safety.
Consider this:

- Some kind of work is measurable. It can be measured in person as well as from remote.

- With around 12 years of experience working in an office, I can guarantee you that 100% of the staff is not working 100% of the time. Maybe 60-70% ish. Why loom around in the office doing nothing when you can be at home and take care of yourself, your pets, your loved ones or cook a healthy meal, and so on?

- WFH is just taking back the time we devoted to work which is not work related such as commuting.
I've gone back and forth from being in management and just a straight up IC. As an IC, I love "work wherever you want and we also have an office and we trust you." But that said:

People that judge managers that want a return to the office as "incompetent" in my opinion misunderstand competence. Competence isn't a spectrum. It's a function that depends on inputs and is matched to some selection of innate traits and acquired skills.

As a manager, if I'm supposed to be managing remote, I absolutely need frequent one-on-ones. I have ADHD that I can't take meds for, and the inattentivety is real. Not to be confused with a lack of conscientiousness, I am much better at managing people in person because I can pick up on social cues in a way that remote just can't. And yes, many workers don't go straight to management when they're stuck. They quietly twiddle their thumbs, and if you dear reader are being honest with yourself, you know this is true at least for a sizeable portion of the workforce.

So my advice here if you're a manager: Daily one-on-ones in the morning with defined goals and blockers. For the most dedicated, weekly is fine. Don't force in office if you don't need it for real work to be done. But make work success clear.

If you're an employee getting pressured to come in: Ask your manager for a daily one-on-one for two weeks to see if they get the sense that things improve first. They can always say "no" and you can always leave.
Gonna be great once the advertising industry finds out about this.
There are definitely problems on both end of the scale, but I’m seeing more of the former definitely - I think it depends a lot on what kind of environment you’re in. I more often encounter people using “premature optimisation” to not do any optimisation at all. It results in applications that have a much lower performance ceiling and more often require a rewrite relatively soon.

Edit: I also want to add that in this specific case with Java, using functional interfaces with primitive datastructures often doesn’t really have any downside. If you know you need to filter the data to a lower scale first before continuing (e.g. to the amount you can display on one page), it’s just not sensible to object box your entire data first, just so you can avoid having arrays anywhere in your code. Just have a class for your data and expose some rich interfaces to it, but implement paging on top of primitive data in this case.
> WordPress’s minimum requirements would be a simple PHP server, without the need for a separate database server

That doesn't help anything. The complications come from the plugins and themes that make the WP ecosystem. Not the WP core itself.

> SQLite support enables lower hosting costs, decreases energy consumption, and lowers performance costs on lower-end servers.

Thats too extreme a stretch. The flower shop owner in Oregon has bigger concerns than contributing to those with 0.0001%.

> This can be translated to lower operational overhead and faster loading times for small-database sites, and that equals money.

It doesn't, really. The reality of the software and infra costs in the industry is that they are already pretty low. And the meager improvement that will come with adoption of anything - leave aside SQLlite - just do not merit the effort that will go into doing it.

Majority of the web hosts already use reverse proxy caches that directly serve HTML instead of ever contacting the database. This applies to majority of the WP traffic including ecommerce traffic. If you are visiting any prominent WP web host as an anonymous user, you are very likely seeing a static HTML being served to you without db ever being contacted.

And in the case the db is contacted if the host does not have a reverse proxy cache or anything, it is only being contacted to get a minimum amount of information with the simplest of queries, and then again, a static page is being served from a caching plugin's cache.

Going further - if you are actually a logged in user, using a WP website without being served a cache and actual WP queries are happening, the chances are high that few of the queries that are happening can ever benefit from any db engine that is 'more optimized'. The majority will just use standard stuff, with MySQL servers that are already optimized for it.

So, all the glorious improvements that you imagine are not applicable in the real world. That's why nobody will lift a finger for it.
Rolls Royce Can't Make a Hearse?
Synchronous condensers and grid flywheels are two different things, the former is synchronous, hence rpm locked to instantaneous grid frequency. These provide very short term stability, and are not energy storage (due to the small acceptable variance in grid frequency), and are normally used for dynamic grid-scale PFC. Flywheels are asynchronous and inverter-driven.

Interesting. I've never heard of that happening before. Can you link a reference to where I can find out more about that aspect of the linux memory subsystem?
I used an approach similar to Peter's here to both an old streaming parsing library as well as a GUI (event handling) library -- effectively, re-use the same instance of the event shell with new data every time an event fired and copy the data out if you need to retain it for a long-lived operation or persistence, otherwise calculate and move on... the reduction in object creation overhead was significant and performance increase was around +30% for doing this in the two individual use-cases... BUT, the API was like a loaded gun pointed at your face.

I knew what I was doing (with it) so it wasn't a problem, but if I over open sourced the API and provided it as a library I would envision a large portion of the population trying to handle the events in a multi-threaded context or throwing them into a List only to find the values changing on them during use (while the parser was still running on another thread).

Performance was so tempting, but usability-face-shot-gun was the greater evil.
The Other “MoviePass Economy”
It doesn't look too hard to remove that dependency, but then you'd have to write your own cross-platform GUI software, which might be out of scope. Might be a fun exercise though.
The line between espousing libertarian beliefs and satirizing them is so thin.
There's good advice there but you definitely need to not go crazy and get into premature optimization land.

If you've got a tight section of critical code like he does this is a good technique, however reuse of the same objects through the critical section implies:

- Mutable objects

- Harder to verify correctness

- Need to be very careful to avoid some very very serious bugs and security issues.

E.x. in his HFT example. Improper reuse of an object without correctly resetting/setting all the fields could create bugs as serious as executing a trade against the wrong user or leaking data between users.

None of this is really rocket science or java-specific. It's all basic old school optimization & computer science.

If nothing else, network effects. Linux uses git, github is popular.
I call your view of this report into question. The hydro section is replete with "Highly variable" as an assessment of impact. One of the largest variables, is "transport of material to remote site"... and if you look at figure 32, this accounts for perhaps 65% of overall "environmental cost", when the bars are averaged.

This can drop to almost zero, if you build a dam near a location with preexisting cement plants, or, in an area where you snap build your own cement plant.

Even steel transportation ; is it local? Is their train? Is there a waterway, which ships can transport steel to you on?

Hydro is so clean, it isn't even funny.
And funnily enough, this is exactly how Linux was born. It was literally started as "just a hobby, won't be big and professional."[1]

The Two Eyes of the Blind Mind: Object vs. Spatial Aphantasia?
Hi!

if I understand correctly, this platform is aimed at employers who through social activities and features, would like to increase employee productivity. Correct me if I'm wrong.

Then I read:

- Join us to strengthen and build new relationships with your colleagues. - So, LinkedIn features

- Learn more about others and build friendships through common shared interests. - like the foundation of the old facebook

- You would be able to get matched up with your co-workers based on common interests! - Tinder without the fun

All this under the eyes of the employer.

It seems well crafted and I compliment you for the effort, but IMO, without any offense, just sincere criticism, It strikes me as one of the nice ideas that come to people who pass more time on LinkedIn and than at their desk.

It might make sense in the eyes of the employer, very little for employees.

I, as an employee, would not use it.

Oh, I really like the colourful little slimes with the hats!

I wish you luck!
I barely come in to the office any more, and this has been fine for me, I know all the senior folks in my org, I have a big meaty project that I am driving that has appropriate staffing, and it's largely not from the city I live in, so I don't really benefit a lot from showing up to the office anyway.

But I also haven't interacted with new folks my org has hired in my city unless I have directly worked with them, which isn't really a problem for me, but I have more experience with our technology/systems/processes that new hires would benefit from, and I am not interacting with them enough to share it.

Anyway, my eyes started glazing over when this post said there was no evidence, since all the big companies have done studies on the effect of the covid shock & WFH. Microsoft published theirs and found that it wasn't totally cost-less, even if primary productivity metrics were not impacted: https://www.microsoft.com/en-us/research/publication/the-eff...

You can argue that the evidence is being misinterpreted, that companies are trying to have their cake (increased task-specific productivity when WFH) and eat it (increased innovation) too, but to say there is no evidence is to not engage with it at all.

In general, I find it unsurprising that someone from an SRE background at a relatively small company is bullish on WFH, the job is largely not innovation focused and is probably one of the parts that is least impacted by the downsides of WFH.

I think we've all experienced too big a shock for things to go back to how they were before, but pretending there are no downsides is just dogma.
The Decoder Ring podcast did an episode[1] recently about the supposed death of the mall. It's a fun listen and covers a lot of the history and evolution of the mall as a concept and how it shaped, and was shaped by, transportation changes in the US. It also goes into the social importance they have had over the years and how that has evolved.
