Disclaimer: I do own a Tesla, and it does not drive like any other car I've drove or ridden in during my lifetime. My Dad says it is like being in a space ship.

No, no, and no. Would I like Mercedes/BMW/Lexus/Audi/Jaguar to have electric vehicles? Yes I absolutely would! But would you have over the air updates, a push towards self driving (even if they're not there yet!), and a very strong push towards sustainable manufacturing if Tesla was just an OHM that sold to those companies? You would not, because they have to cannibalize their own ICE business to fund / push their EVs. The world is better off with Tesla standing alone as a single company, whether or not they succeed.
When will founders decide that accepting Chinese VC funding is unethical? The money feeds back into a system that gives human rights very little value.
Once you become an OEM< you're giving up power and manufacturers will want some ability to dictate what and how things are done. That seems more restrictive than their current model.

As far as Merc/BMW/Lexus/Audi etc... they're all in the electric game now because tesla popularized it and proved the market. If they hadn't done that, its unlikely those brands would be releasing top luxury vehicles with electronic options now/in the near future.
Partly.

Toward the end of the Bell system, AT&T used Unix to run the control plane of phone switches and also to do administrative tasks for the phone network. I remember a paper in the Bell Systems Technical Journal where they did auditing of billing records for the whole U.S. with a set of tools kinda like grep, awk, etc. but with binary-format data records.

There are situations where operating systems get behind the 8 ball and there isn't a perfect thing to do. Giving up to prevent data corruption is one choice, but trying to soldier on and do the best you can is another.
The vanilla APACHE_RUN_USER/_GROUP is daemon/daemon so they're fine. daemon and nobody are users that by definition have no permissions on the host.
I tend to view scrum, kanban, XP and also the more traditional tools like V-model as tool boxes - or maybe some kind of pre-configured framework. They combine agile or other project management tools in order to solve problems the team or stake holders of the team have.

However, this doesn't mean you can't take out and exchange parts. Some teams work profiles fit well with set sprints with a stable set of tasks. Others, like ops work with few people, doesn't due to incalculable factors like incident management. Prioritization might need different mechanics depending on the position and the responsibilities of the team.

It's all a big grab bag of tools to create some working workflow for a team.

I think it is better to record the facts about people's opinions, than to count reputation points on identities.

For example, as ternary predicates:

1: water is wet

2: identity_1 corroborates 1

3: 2 by_way_of blind_faith

4: identity_2 denies 1

5: 4 by_way_of blind_faith

etc.

You can go as far with this as you want, and the consumer gets to decide what establishes or hurts credibility, and which statements of fact corroborated by what methods and by whom will either count toward or against the credibility of a specific form of statement on a specific topic by a specific set of identities.

For example, you could have predicates describing conflicts of interest, and identify the relevant conflicts of interest by querying for interests in the predicate in question to find what people you trust will say about the interest of individuals and organizations in corroborating or denying a particular claim.

You could also have predicates which show ways in which a statement is controversial in its general form, but is uncontroversial when refined. For example: liquid water can not be wetted with liquid water.

You have experience, use it to improve your product/team/company. You have to stand behind your opinions and push to make yourself heard. Take control of your time. Be willing to lose your job, whether it's from quitting or being fired for muckraking. Best shot is probably to find a small company that gives you a better culture and more opportunity to shine even if it means a little more effort. Google local venture funds and reach out to companies among their portfolios, if possible, or find remote work if there's no nearby tech/business scene. Linkedin, Indeed, AngelList, StackOverflow., TripleByte... there's no shortage of job boards. But no one is going to apply for you. Find ways to build your courage and self-confidence outside of work if nothing else. Physical hobbies are great for this, especially rock climbing which requires directly overcoming fear of failure to achieve success.

Mid-thirties is nothing. A team I used to work for hired a couple older devs (much older than you) that were truly terrible, and they are still at that company. Jobs are out there and if you're any good you'll find work. Don't let your age be an excuse. You can't change your age. Only valid excuses IMO are dire financial or health issues - repairing those would be priority number one.
Because I monitor my resting heart rate obsessively. :D

At 6800 feet (where I live) my resting HR is 55BPM +/- 3 and falling because I've begun to train hard coming off of a really bad injury + surgery. During recovery where I was unable to exercise it drifted up over the months to 62BPM. As I get back into my best condition it'll fall into the low 50s.

At sea level my resting HR will fall by 5-7 beats for a couple weeks and then drift back to stasis over 6ish weeks my body reduces its red blood cell count and all the other acclimatization stuff. I try to avoid this.

I watch it pretty closely because as nabla9's excellent commentary in this subthread highlights, a persistently elevated resting HR is a sign of overtraining, which being a type A obsessive nutjob I am pretty susceptible to. :)

I've also found that an elevated heart rate that can't be explained by overtraining, for me, is indication that I've got an incoming illness that I don't feel yet, usually a sinus infection.

So the Navigate on Autopilot that now will change lanes on its own (without driver input) isn't a step towards full autonomy?

> Taxis and Ubers are forms of public transportation, and likely reduce the overall number of cars on the road.

This doesn't make sense to me.

IME - the vast majority of time there is a single customer or group in a taxi or uber. Assuming this is in fact the case. Taxis and ubers increase the number of trips taken by vehicle, but let's pretend in their favor that they leave that number flat. While they have a passenger in them they are trading 1-1 for a private vehicle to a "public" vehicle. While they don't have a passenger in them they are trading 0-1 for private vehicles to "public" vehicles. That results in a net increase in vehicles.
Exactly. I would just appreciate footnotes in the articles I read that gave a detailed explanation of how much fact checking was done.

That way if a story needs to be expanded upon at a later date, the next journalist can dig deeper easily picking up the trail where the previous journalist left off.
Indeed, I specifically avoid "professional" engagements because I have no interest in being published in a gallery, or in dealing with the art world or with clients.

Compiler is also going to make an impact which for me is consistent across both grep binaries.

FreeBSD clang version 6.0.1 as well as -O2

I suspect there are still edge cases where BSD grep is quite a bit slower or not compatible with GNU grep. However with a closer apples to apples comparison there isn't much difference anymore for my usage. Which is a lot of grep use but that is pretty vanilla.

There may also be other OS differences in our comparison. My tests where run against a fairly recent FreeBSD 12-STABLE.

For most people that’s not a problem in the UK. Partly that’s because all employed income has to be reported to HMRC by your employer, and party we just don’t have the same system of tax deductions - you can’t write off charity donations, and expenses are only deductible by companies. For children you have to register for child benefit payments with the government.

Even for the self employed it’s generally a pretty simple process of filling in your income and expenses and then everything else is calculated for you.

the analogy with "listen to music" is not "read the code" it's "use the program" but definitely composing and playing don't use at all the same skills as programming. For example it's easy for me to see where a bug is but when I compose music, I hear something sounds wrong, I don't know if it's "un-harmonious wrong" or "interesting wrong" and a piece of music doesn't "work" for me the same on 1st listen, 3rd listen, etc... whereas a program is by essence repeatable. And as a result I don't really attempt to "fix" wrong music if I feel I went wrong with an idea I just make a new one. Whereas with code I was debugging from the start, even when I was new and unconfident.
The problem is that SD cards were designed for portable storage of photos and music, which is a completely different use case than running an OS or database on top of them. They're being asked to do something they were not designed for, and then people get upset about it.

They make high-endurance SD cards that have the same (or better) reliability as SSDs. These are what should be used in any Raspberry Pi that does some non-trivial amount of writing to the disk.

Or boot from USB or Ethernet.
False positives will be much more rare in practice with the new guidelines used (Lung RADS) which cut false positives by 50% or more while mostly preserving sensitivity.

That doctor should really update his diagram to reflect the current standard of care for lung cancer screening. Using the false positive rate from the 2011 study is intellectually dishonest!

In addition the amount of lung cancer deaths prevented was doubled (!!) in a recent European study by tracking patients for 5 years instead of 3 years.
Another hilarious example is Steve Johnsons (and companies)s casimir force paper which was copied figure by figure by some Chinese researchers. Absolutely nothing happened to those Chinese "scholars".

Just because you can do something does not make acceptable to all people.

Ask HN: AWS continues to charge me even though a hacker uses my account
Around 8 months ago I lost control of my AWS account after a prolonged social-engineering campaign against my account. Although it was a nightmare, thanks to a robust offsite backup solution we were able to quickly migrate to google cloud (which has Advanced Account Protection, a godsend for anyone in my position).

Strangely enough, even after several attempts I was never able to recover my hacked AWS account (from my support calls it seems like the attacker changed the email, name, address) and have never been able to authenticate against it.

However the one thing that was never changed is my credit-card. I have offered AWS support several times to give them my credit number and ask them to unlink it from the account, but they refuse to do so without me being authenticated.

I don't want to get on Amazon's bad side, but with no options left I have been resorting to charge-backs on the credit card. Thankfully my bank has been siding with me, and each month I have been winning them -- but next month the new bill comes and I forced to repeat the process.

Not wanting to get a bad reputation with my bank or Amazon, I just asked my bank to send me a new card. But amazingly (?!!!) the next month the bill from AWS still came on the new card.

It's now been 8 months, and I'm sick of the absurdity of the situation. Is there anything I can do?
How to choose the best ad platforms for your business
Poor taxpayers spend 200+ dollars to file their taxes. Every single one of my employees goes to H&R block or some tax guy to pay taxes. Almost all of them have 1 job. Most of them 1 or 2 W2s and most don't houses.

We own a house, two high-tech incomes, and loads of 1099Bs to deal with. IOW, I can't imagine the tax situation of your employees is any more complicated than mine. In previous years, I could whip it out on a Saturday morning. This year, it was an hour of importing forms electronically, if that (umm, thanks, higher standard deduction?).

I'm not trying to take away from your point, I'm still chafed each year that I have to give money to TaxAct (at least they don't lobby for complicated taxes, AFAICT). But taxes aren't that complicated for simple situations. Maybe have an hour brownbag or something on "here's how to enter the control # off a W2 and import it. Import from Fidelity. Sorted."?
When people talk about cost of nuclear vs wind the issue is that you can not go to a wind farm and get a contract that give 24/7 energy at a set level for $0.02 kWh. What you get is a contract that give you $0.02 kWh when the wind farm is producing at peak capacity, and then you have to buy the somewhat more expensive coal and gas produced energy whenever the wind is not at peak capacity.

It is like comparing the transportation cost of rail vs trucks. It is obvious that the price per km is cheaper for the rail. If what you want is to transport goods between two railway stations that has excess rail capacity it going to be extremely cheap compared to have a truck driver.

$ per kWh is not relevant. $ per contracted supply of continuous power 24/7 is.

The video even mention the wind + solar + battery, but is questionably if the average output of all three puts it better than nuclear. A benefit however over nuclear is that such constellation can be created independent of each other with shorter investment spans that nuclear.
The flip side to this is that they always seem to have some sort of short-term problem going on. One quarter it’s trouble ramping up production, then it’s quality issues, pissing off regulators, inadequate transportation, what have you.

You can see this as “they are good at overcoming problems” or as “there’s always something going wrong.” I tend to see it more as the former but seeing it as the latter may be a sensible explanation for the stock movements.

Ubers have been shown to increase vehicle miles driven, which in turn means a decline in the use of public transit. Historically the big tax on cars was an 18% tax on parking in NYC, but considering that more and more people are taking Ubers instead of driving themselves, we are still effectively subsidizing uber use in a way we aren't for regular driving.
> But the Chinese nationals I work with weren't particularly pleased with all the westerners speaking on their behalf.

Just because someone thinks their company shouldn't engage in a specific project due to ethical concerns, that doesn't mean they're speaking on behalf of the people affected by those ethical violations.

It's perfectly reasonable to want to stop the project due to the ethical principles alone.
Ask HN: What's an Example of a Successful Rebranding?
There have been many rebranding in the past of big companies that have largely received a negative response from its userbase and the community at large. Examples include Slack's recent logo/color/design overhaul, DropBox and its new radical color combinations, Windows 8 and its Metro design language, etc.

Is this "backlash" over new designs just a user's reflex action to change? Or have they actually been detrimental to the company (due to mass unappeal)?

In continuation, what are examples of "good" or successful redesigns that were positively accepted by, if not all, a majority of the users?

Thanks!
I've seen Agile™ estimation break down when the task is either
1. something nobody has done before (or has no close analog), or
2. is so interconnected that it can't be broken down.

The former is just a matter of hiring more experienced engineers _or_ allocating exploratory/prototyping time. Still high uncertainty but these kinds of tasks become rarer over a time.

For the latter, the common refrain is "break it down" but there certainly exists a relatively common type of work that must be completed all at once. And I find it increases as the complexity or popularity of the product increases, so with time. Therefore perhaps the metaphor of building becomes less appropriate, and surgery paints a more accurate picture.

Builders can construct a house, then add a garage, go work on another house, then return and add a guest bedroom, then remodel the kitchen, all with relatively minimal pausing or switching cost. But once a patient is put under and opened up, the surgeon really should work on finishing up that one patient before moving on to the next one. And for some weird reason we tend to prefer one big surgery to multiple small "atomic" ones.

Granted most of these are collaborative ventures, but calling China 'catching up' at this stage is ignorant.
> Why doesn't it infer them from the structure of the database (the relations between tables)?

That's because the structure doesn't always has the feature which you need this specific time to rely upon. And that's a feature, not a bug, which allows having flexibility between data structure and data queries.

If you have a relation, DB engine maintains that, ensuring integrity defined as such. However, you are free to query non-integral (in this sense) references, which you're able to describe in queries. If you won't be able to specify joins, you'd have to always express relations in the structure. Since queries in SQL can be arbitrary, to reach parity with flexibility you'd have to have all possible relations. Then you have the problem of choosing what you need for this moment. In other words, some relations are not known before query time.

Lots of people do, it gets lots of talk every few years, and nothing happens because the people that don't want it to happen do so a lot more intensely than the people that do want it to happen want it (because the former literally have major businesses that depend on it not happening.)
Facebook's basic concept is not bad. It's precisely their business model relying on advertising as the main source for revenue that is causing all sorts of interest conflicts.

Due to the nature of this business model, Facebook no longer serves its users, instead the platform has been tailored and customized in every possible way to exploit their users for its own profits, by selling their personal data/information to the highest private bidders, very often done behind the scene without much public awareness.

Having said that, the frequency of bad news about Facebook that seemingly keeps popping up every day is suspiciously abnormal. There must be an external force that is being dedicated to digging all the shit up at Facebook right now. You literally cannot go through a day without seeing new scandals from them on your news feed. An organization with security measures like Facebook's is incapable of leaking bad news at such rates by itself.

Don't want to mention their names here, but are these retaliation actions coming from those who had been previously wrong by Facebook?
