The secret to a great gas station business, is being not primarily in the gas station business, but in the higher margin food business.

The Sheetz gas station chain along the US east coast for example has a wildly thriving business and is demolishing every other gas station in its path. ~25 years ago they started doing things quite different than all the other competition and it has led to them building out hundreds of locations. They're up to $7.5 billion in annual sales now. It's all built around great locations (of course) and the margins in their food making business. They did touch screen ordering kiosks as early as any other major food-related chain in the US, and 20+ years before McDonald's deployed them widely. The gas merely draws traffic, there's no serious money in that part of the business.
What I was asking is why would you design a font that makes it easy to confuse iIl|1O0, etc... we need to get rid of those fonts.
I experimented with it on my iPad, and came away frustrated. I definitely like to use my iPad when practical.
What's surprising is that the question is "what tech to learn?" but most answers (also his own suggestion) are mostly about frameworks and programming tools.

My suggestion would be to actually look into "tech" such as distributed systems (CAP theorem), DDD/Event driven architecture, CQRS pattern, workflow automation, etc ...
This was one of the comments posted below the article that may answer your question:

Epistemologist2:
As a physician myself, with Type I diabetes for the past 56 years, I have lived through quite a lot of change in the management of my diabetes. I am particularly concerned about the discussion in Myth #2. The inexpensive insulin, U-100 Regular Insulin, is readily available and it is just as potent, unit for unit, as the newer synthetic insulins. What is different is the rate of onset of action. Regular Insulin does not "turn on" as quickly as the others, but if taken in advance of a meal will do the job sufficiently well that you can maintain reasonable blood sugars. The over-riding intent with insulin therapy is to mimic natural insulin production/action in one's body. The expensive modified insulins become active much faster and consequently will more closely mimic natural insulin release, but it is critical to note that once injected, those insulins do not turn off as promptly as naturally produced insulin from the pancreas, and this can be a serious problem!

In my case, I had had my diabetes for about twenty years and was adequately controlled using those "old" insulin products extracted from beef and pork pancreas after which we got the now inexpensive Human Insulin, chemically identical to that from the human pancreas, and it did not "turn on" any faster than the predecessor products. It was not until 1996, 33 years into my own diabetes, that we saw the introduction of a synthetic insulin with much faster onset of action.

Bottom line is that the price of the fancy new insulins should not be such a barrier that it leads to one's death. The inexpensive older products work, just like you old "dumb" phone works to do its basic job. Newer is better, but not critical, and neither doctors nor patients should forget that using older techniques and products is a viable option. It is the doctor's failure to think outside the box to adequately educate the patient that causes death.
Kind of a tangent but does anyone know the name of the recently discovered sub-dermal tissue? It a network of fine capillaries (that have something other than blood in them) IIRC.

It wasn't discovered previously because it shrivels or thins out after death, something like that.

I remember reading about it a few years ago. It was like we had found a new organ.

I believe by total revenue iOS is bigger — not per user (although that’s implied), but I could be wrong.
I am the maintainer of these roadmaps https://roadmap.sh/roadmaps if it may help.

We are in the middle of updating them for 2020; frontend roadmap has been updated, backend and devops are expected to be published in the next couple of weeks. Also, one of my goals this year is to make these roadmaps interactive with clickable nodes, adding details for each and making them easier to follow for beginners.

Genera supported in fact multiple languages, though I believe Lisp was used as intermediary representation.

There was even support for C, good enough that there's a demo video of libpbg being compiled and used.
Also apparently one of these tools has a lot of detractors. Who knew?
The interest in black-box models is partly for the reasons given, that it is presumed that their inexplanability makes them more powerful, but also because business people are sick of dealing with programmers and analysts as a class, people with arcane knowledge limited replacability, and a penchant for blowing deadlines.

The dream of machine learning is to fire the programmer and break up the last trade (baring doctors and lawyers).

If it was just business people being alienated, I'd say fuck it they deserve it. But the fact is everyone, and many of the programmers too, are alienated too when much of the code makes sense to no one. I would rather fix programming to be comprehensible to more people even though it will take down the walls between programmer and non-programmer.
It's free? Does that mean you'll work for free until it's done?

The idea that anything is free is ludicrous. You are either spending time (wages) or money (buying solutions).

Why would £40 million be a lot of money for the IT systems of the entire public healthcare system in the UK? The NHS has a yearly budget of £114 billion, so this particular IT spend is only 0.03% the size of their yearly budget.

There's nothing decadent about this. It's essentially deferred maintenance that is long overdue, probably overdue because the government had to wade through people like you who can't help but complain every time a government organization wants to invest in modernizing.
Absolutely. I don’t know what this tool is about, but the README statement is wrong; I can’t think of any distribution dumb enough to use performance governor by default. Most Intel-based platforms use Intel-specific governors.

I developed an energy-aware DVFS controller for HPC clusters a few years back, and there was no such thing as performance by default even on compute nodes.
In 6 months driving a Renault Zoe, I have been in gas stations twice. Once for killing time during a rare not at-work charge, and once for getting a snack for my son.

Gas stations are dinosaurs that haven't heard the shockwave of the meteor yet.

And who will set that up for £0/hour?
Basically Linus is right.

One caveat is that calling sched_yield is a fantastic throughput optimization for the spinning portion of an adaptive mutex. If you have parallel code that sporadically contends for short critical sections then my data has always said this:

- something like a futex lock is optimal

- you want barging, not fairness

- spinning the CPU is a t
questionable idea even if you do it for a short time. The pause instruction does something like jack and shit. Busy waiting of any kind seems great for microbenchmarks sometimes but it’s pretty bad for anything complex.

- spinning 40 times while calling sched_yield prior to futex_wait (or whatever) appears optimal on many schedulers and benchmarks. It’s hard to tell why. Best I can tell it’s because in the large parallel apps I’ve worked on and benchmarked, there are often threads that are ready to do some useful work right now, so yielding from a thread that can’t get a lock to one of those is a system throughput optimization. If there are no such threads then it’s a bit like spinning the CPU.

The 40 yields thing has a funny story for me. I learned of it from a comment in the JikesRVM code that was more than a decade old claiming it was optimal on their custom scheduler on a 12 core POWER box running AIX. The benchmark cited was something I’d never heard of. When I rewrote how JikesRVM did thread scheduling, I was sure that this would need tuning. Nope. It’s optimal on Linux and Darwin on x86 on basically any Java benchmark that has lock contention. I later implemented the same heuristic in WebKit’s locks. It’s still optimal.

To be sure, there is a broad plateau of goodness around 40. Like, 50 is about as good. But if you go order of magnitude in either direction, performance tanks. I’m superstitious so I’ve stayed with exactly 40 whenever I have to write this code.

I wrote a lot more about this stuff once: https://webkit.org/blog/6161/locking-in-webkit/
Many people who worked on UNIX for years had plenty of experience with the kernel dumping core. I ran LINUX in the mid-90s and it wasn't extremely stable.

Much of this contradicts my N=1 experience. I have controlled my type 2 diabetes by keeping my carb intake below 25 net grams per day.

* My diabetes controlling diet is high in fat. I have found that without the presence of carbs, fat is the safest macronutrient in terms of keeping my blood glucose level down. I can eat fat and protein while barely budging my levels.

* Sweet desserts are not okay, not even once in a while. They make my blood glucose soar, and it can take days to get it back under control. I get some of my diabetes symptoms and carb cravings back within hours of indulging. This is not about sugar though, it's about all of the carbs I've tested, including fruit. Sugar seems to act just as a concentrated carb.

* Yes too many sweets can give you diabetes. I believe that's how I earned it, by indulging my sweet tooth for year after year.

It seemed like an extreme change for me to go low carb, but as a result I have a reasonable blood glucose level without any drugs. And the actual change was more joy than slog. I now love this way of eating and don't (much) miss the high carb foods. I'm afraid this myth buster needs some of her myths busted.
What are your arguments against the JVM if I might ask?
And they rate their existing shows TV-MA for no apparent reason. Why is "For All Mankind" unsuitable for children under 17?
We are a long long way from that.

And even if so driverless cars won't give them any other business, as well as drastically alter the desired locations of the stations.
Taking a lead from GDS and starting to create user-friendly, predictable applications with a shared design language and reusable components (like SSO, email/SMS/letter sending) would be a step in the right direction.

They've already stated but it will take a long long time.

From what I can tell, it's setting some kind of cookie for Youtube as part of the standard Google login flow. They probably have their cookies set up in such a way that authentication data is only accessible from first-party websites (like cookies).

I can see 11 cookies on the Youtube.com domain in my browser. Some of those seem to be purely for authentication reasons. I'm pretty sure that's why Google flows through Youtube when you log in.

As for why they always try to set Youtube cookies: I don't know, but it's probably because they don't feel like splitting up their authentication flow. Doing the redirect for accounts even when they don't have any Youtube-related is probably a no-op; leaving it like that doesn't cost anything close to the time and resources it would take to segregate their entire workflow + verify that the security is still sound.
I've not had the same issue on my Thinkpad X1C6. I think I installed TLP and Powertop but the battery life is better than Windows for my use case.
Not only SSO, but also two-factor authentication. Without asking for the user identifier first, you don't know which authentication method to present, because this varies per user account.

The alternative is to let the user choose the authentication method right on the first screen, but that would mean showing all possible methods (some of which may be limited to certain groups of accounts) and getting a lot of users stuck because they chose the wrong method.
How is this related to SysML?
For All Mankind (the only show I've watched on Apple+) also has a bunch of adult themes, if not graphic sex and violence. People are having sex (straight and gay), committing adultery, have drinking problems, are dying in horrible accidents, etc.

The lack of graphic sex and violence on TV+ doesn't strike me as a big deal since, on the same device, it's available a click away from other content providers. Plus, nothing prevents you from streaming anything you like via AirPlay.
> The NHS has a yearly budget of £114 billion, so IT spend is only 0.02% the size of their yearly budget.

You might want to double check you math.

But yes, it's such a small amount of the overall IT budget I almost wonder why it's being given separately.

First the IE-only website, then the Chrome-only one. In the future, archaeologists will be able to date web apps based on what browser they support.
That argument is nonsensical... Just because something is "not a necessity" it's reasonable to criminalize its possession?

Eggs aren't a necessity, there are plenty of alternatives available. Should we ban them too?

The causal argument suffers from a problem of nomenclature.

On one side we have the colloquial understanding of cause and effect where a cause is a true impetus of effect. On the other side we have "causal" learning in biology where you're not actually learning causes, just strong correlations. We can learn just about any temporal association even if there is no direct cause-effect relationship. Random reward structures are a way to illustrate this: present a reinforcing stimulus to an animal at random times and a random subset of behavior will increase in frequency. The animal develops a false "causal" belief that a series of its actions is influencing the presentation of a reward.

That's why I like focusing on "sequence prediction", even colloquially we know predictions can be wrong. Those predictions can be influenced by low-d world models, but you don't accidentally elevate that model to claim a pure/symbolic/accurate model as can happen with incautious use of the words like "causal."
> Apple TV+ is so locked down with DRM that you can't even easily take a screenshot from a show and share it on social media.

This seems incredibly blind. Do they realize how much culture spreads via gifs these days? If anything exporting clips and screenshots should come built-in.

This is a pretty simplistic comment that seriously underestimates how complex this stuff is. (Are you Dominic Cummings by any chance?) IT systems like the one in the NHS are huge, have grown organically over time and are mission-critical. You can't just trash one system and start from scratch (witness the Universal Credit debacle in the UK). It's like repairing a ship while it's sailing. Yes, there's quite a bit of money involved, but I can only imagine someone who writes a comment along the lines of "it's easy, just do X" has never touched a system like this, or had to write budgets for it.

I'd also like to see you walk into a situation like this, no matter how much power you had, and see how far 'Arguments about "but corporate / compliance / vendor contracts / red tape" be damned.' gets you.
Didn't that quote only show up after the guy that allegedly said it died?

> the giant resonance mode. In this mode each novel idea, once it appears, spreads in an explosive manner in the theoretical community, sucking into itself a majority of active theorists, especially young theorists. Naturally, alternative lines of thought by and large dry out. Then, before this given idea bears fruit in the understanding of natural phenomena (due to the lack of experimental data and the fact that on the theory side crucial difficult problems are left behind, unsolved), a new novel idea arrives, the old one is abandoned, and a new majority jumps onto the new train.

Reminds me of Jamie Zawinski's "CADT Model" of software development. There seems to be a dynamic in many fields where fixing known problems or finishing a project doesn't seem important to many people.
The licenses clearly do not pass the free software definition or the open source definition, but I don't think that is what the author is arguing. Their point is that the license is not legal and enforceable.
I suspect his hiring strategy plays into it. He hires immigrants from his own church. That probably plays into workers that will do all the little stuff that makes the difference, even at gas station wages.
I just tried it on every platform I have access to; Android, Linux, Macos, Windows and Chromebook. I was able to take a screenshot of a show playing on Netflix on every one.
It totally depends on your power generation. Here in Quebec we have 97% hydro, so charging at night won't be more expensive than charging during the day.

Talking of Attenborough, it's difficult to stay hopeful after seeing his one hour Climate Change - The Facts, despite Attenborough's optimism at the end. The time lapse sequences from satellite of deforestation, destruction, pollution etc to an extent rarely seen really puts our species' suicidal, destructive tendencies in context.

For me it was far more "we're fucked" than inspiring call to action. Haven't given up trying yet, though I am not at all hopeful now.
I read this as too violent/unfriendly to amass substantial interest from people, not a value judgement per se.
Now I am wondering when we might see our first steampunk-inspired skyscraper... Someone with Bitcoin/Startup fu money expressing their taste. Maybe someone taking over a block and attempting to recreate a scene from Blade Runner?

Meanwhile, Apple has billions in cash on hand. I hope they open their platform up some though, or they need to make some very compelling shows. We’re talking enough for a hardware purchase in a household with no other iOS devices present. If anyone has the resources it’s them.
If you know anything about Seattle it can be pretty easily implied what his business actually is doing. He buys gas stations in "up and coming" parts of town with high traffic and makes them safe by driving out the undesirables thereby increasing traffic from the wealthier residents who don't want to be hassled. Seattle has become big and increasingly unsafe so businesses that can provide a sense of security for their customers provide an increasingly better value proposition.
I don’t know if you’re asking rhetorically or not, but the honest answer is we don’t know yet.

It’s precisely Fussell’s position in his Class that old-money families learned some time in the early 20th century to live invisibly—an old-money house will be so far off the road you can’t see it from there, modestly protected by a gate and perhaps fence. He hardly treats of these people at all, as they’re rarely encountered by those outside their social circles and a little less prone to homogeneity than most of the other classes, aside from a general “calling attention to oneself is NOT what one does”.

Under Fussell’s analysis Trump’s displayed taste in decor and clothes are about as Middle as could be, thought not a small amount of Fussell’s Proles’ taste creeps in in his clothes and food. Imitating the baroque and “living large” while wearing expensive clothes that don’t fit is what one might expect from a high-dollar lottery winner who used to hold some middle position at a bank branch.

I just swapped from using Clojure to TypeScript at work and I can't feel any different. Types are really useful at organizations where people need to work together, Spec has been largely underwhelming on this front. I wish more attention would've gone into core.typed. Hickey has generally spent most of his time with the language choosing other peoples great ideas and picking the right set of them to combine for Clojure. Spec feels overly ambitious and more like a research project than something than something fundamental.
Both of the above comments unfortunately reflect a deep misunderstanding of Jewish way of life. What is generally thought of as God is not what Jews refer to as God, and with time and study, the difference between the two can be properly understood. Also, there's no fooling going on.

> Ideally cars should charge when the sun is up, in day time. If they were self driving, it could charge while we work.

Ideally cars should charge during times when energy is cheaper. This could be at times of lower consumer demand, like at night or at times when prices are cheaper because variable and barely off at all controllable renewables are dumping power into the grid, like when it’s especially sunny or windy.

Bio-coal: A renewable and producible fuel from lignocellulosic biomass
I am not an orthodox Jew but I do like to investigate the truth of things in religions.

I was always wondering how the Manhattan eruv was a “valid” one by orthodox Judaism since a street like Broadway — or really any street — is a dirshus haRabbim which can hold over 600,000 people at once (and perhaps does once a year, also counting the subway).

An eruv originally was supposed to unite “private” domains into one super-domain. The tradition holds that it was instituted by King Solomon himself, to unite Jews who otherwise would not be able to carry things to their neighbors.

So I checked — and it turns out that the rabbinate which oversees it is actually not orthodox, but reconstructionist or something. It is based on Monsey, which is home to many orthodox Jews, so hearing that the eruv is overseen by Monsey sounds like it’s orthodox.

I don’t know any orthodox Jews who use it. And eruvin are basically used by orthodox Jews.

(Fun fact: it doesn’t go through Moshe Feinstein’s old neighborhood, Chelsea, where I used to live, because he opposed it. Another rabbi who opposed any eruvin — even kosher ones — was Menachem Shneerson of Chabad. So in crown heights there is an “eruv dispute” between the orthodox, who use it when they eg walk strollers with their children on Shabbat, and the ultra-orthodox, who refuse to use it and post signs that it’s not to be used: https://forward.com/news/345405/brooklyn-eruv-feud-spreads-t... ).

I think this is an interesting topic for Hacker News because the people here often investigate rules and reasons for them, and this whole topic — even the Talmud eruv rules themselves — is about rules and hacking in a way.
