Yep. The 4-year graduation rate isn't great, but almost everyone gets there eventually. I know plenty of people who just kept plugging away, dropping classes in the 10th week if they were going to fail. One extreme outlier took 17 years.

One of the best pieces of feedback I got at Heroku was don't stress too much on it being perfect. In fact you can make it rough as if drawn on a napkin so it intentionally isn't visually polished and it accomplishes its goal. I in fact started doing some of this way back at Heroku 9 years ago and the approach worked well. Now I've leveled that up with an iPad and paper.

Yes, there are places that have designers and they're a great resource, but don't let that be a blocker. If a company has a designer that can be dedicated and support such awesome. If not just try something and see what works, then keep using it.

I'll also note that we asked Craig for eng blog advice way back in Jan 2017, and he was very helpful. :)
You might want to check out Bidirectional Linear Probing, which can handle load factor >90% with good performance. I implemented and benchmarked it here: https://github.com/senderista/hashtable-benchmarks. Storing integer keys as their hash values (using a reversible hash function) also helps performance. I implemented a dozen or so 32- and 64-bit reversible integer hash functions in the same repo.

So some of the responses to you seem to be missing the point. I agree with you, and with a health check being the wrong thing to circuit break on.

Not matter how complex a health endpoint is, the circuit breaker is more so. The health endpoint might make a legit request, checking all downstream services, etc etc, to confirm that everything is working...but the actual traffic is many different requests, with different code flows.

As an example, imagine service Bs health check actually makes a request. Great. Only, service B is misconfigured to talk to staging, whereas the upstream, service A, is in prod. The health check may always pass; after all, the staging request's data all gets resolved and handled appropriately. The upstream one, however, leads to constant failure, as that data doesn't exist.

Health check passes 100% of the time. Actual upstream calls pass 0% of the time. Don't have your upstream calls circuit break on health checks; have them circuit break on actual responses.

(And yes, you should have network isolation between staging and prod so that particular example can't happen. It is intentionally a contrived example)

> people in sales, marketing, or in management positions -- have grown up with computers.

This doesn't mean anything. Have you watched some 15-22 year olds interact with computers lately? (I'm 23, for reference). They don't hunt and peck on the keyboard in stereotypical fashion but they're just as clueless for anything besides basic interactions. They -are- essentially tech illiterate once they step outside of google sheets, etc, or the web browser in general.

I'm tired of hearing people say "digital native" like it means anything with regards to tech literacy. We're going to have another generation come in and take power that has zero idea of how computers function. At least we understood this and factored this in about the last generation- now we just assume the new generation knows things because they grew up using apps.

If anything, the new generation is more illiterate on average, but with better mechanical facilities and understanding of typical modern UX for apps.

technically it is not wrong, after all it is backed by actual, true science. That being said, this estimation assumes that nothing will change, so no working counter measures of any kind.

In reality, you have China. They are nowhere near these numbers. In Germany trade show get cancelled, events get cancelled, soccer games take place without spectators, schools close. Quarantine measures will certainly be put in place as well when needed. All this helps to keep infections down and slow the spreading. It worked in China after all.

I am no expert on diseaes, but I did my fair amount of number crunching. And that tell me that just taking the current average of deaths and infections, currently somewhere around 3.4%, extrapolate the number of infections worldwide and multiply the two doesn't fly. At the very least you have to brake down the world population by age groups based on the same groups we have specific mortality rates for. doing so already gives you a better picture and a more realistic number. Nobody who comes up with expected fatalities seems to bother to do so.

Obviously, that leaves the whole impact of counter-measures out of the equation. it doesn't account for time nor for any regionl clusters of people. Neither does it account for any local shortages due to an overwhelmed medical system for certain periods in certain regions. Or for any steps taken to counter these effects. To properly do so requires a full scale modelling of this thing. unfortunately the numbers are changing quite fast, so building these models is quite ifficult i suspect.

You would also have to account for margins of error and the fact that testing is a major influence in any parameter of this model. And testing varies highly between countries.

TLDR: The numbers a re a mess, calculation and modelling is difficult and everything is changing daily. Good luck with coming up with any reliable predictions.

I would love to see numbers for testing so. Especially how many tests have been conducted by region, how many where positive and how many negative. Ideally over time.

I think there's a major understanding of this part of AA. This DOES NOT mean acknowledging that you believe there is a god. The concept of a "higher power" can mean anything you want it to mean. You can imagine your higher power is Gandalf, Sauron, elves at the bottom of the garden, or even some aspect of your "best self." You could imagine it to be the spirits of your ancestors or even something like the energy of the universe.

The point is surrendering to something "bigger" than yourself. Don't get tied up in militant atheist perspectives.
> Anecdotally, I've known someone who used to be stressed out and controlling. Last time I saw him he was not so stressed. He said his life changed once he surrendered and accepted his destiny. He didn't go religious or anything, just 'accepted' his fate.

That's something I think about slightly. A lot of adult life is anxiety based on seeking optimal something. After years it feels like fear of death causing over analysis and cramping. Then you just go back into average life and maybe (at least my belief) realize it's ~peak. The anxiety is maybe even a nature trick to make us learn adult life complexity and maybe improve the status quo a bit.

While that may be true, it is in no case at all a reason for panic and panicked behavior such as rampant hoarding of things one won't even conceivably need for the length of time this is reasonably expected to last. I have seen a large number of rather hysterical comments on this site that have openly proposed that yes, people should outright panic. It's absurd.
Dashboards are great for correlation. After an alarm fires you check the dashboard and compare all the graphs at the time of the incident. It's a great way to get more information about what is and isn't broken.
In India it is to fulfill the ego of professors nothing more.

One good thing about Corono is that it forces online education like the recent MIT online classes, hope this will set a chain reaction and take the monopoly on education from traditional colleges.

> In ASCII every character is a byte, and in Unicode, that’s often not true, a character can be 1, 2, 3, or more bytes.

In a similar note, Unicode isn't really about bytes. Unicode is essentially just a huge map of numbers to characters descriptions. UTF encodings convert those numbers into a sequence of bytes, and vice versa.

Float Launches Time Tracking to Remove the Guesswork from Timesheets
For a site focused on "clarity", I sure didn't make the formula very clear :) I will work on clarifying it on the website.

The formula is a combination of:
40% - new cases / total cases (indicator of how much things are blowing up)
40% - absolute number of new cases (indicator for whether things are slowing down or not)
20% - recovered cases / total cases (indicator for recovery progress, although not all countries seem to post their recovery data)

The formula itself is somewhat arbitrary, but I felt it was a decently good metric that summarized the situation in every country. I'm open to suggestions on how to improve it as well!
I think the bigger risk is you write a blog about some "cool stuff" you are doing and it's actually not cool, it's dumb and obsolete and people who might have been thinking about working at your company go apply to Microsoft instead. There's abundant examples of "How we handled a billion queries per year with only 1000 servers" out there. It's the risk that you don't know how you really compare to your peers.

Personally, the only "technical blog" I want to see from a company is papers accepted by OSDI, ISCA, VDLB, etc.
> Tesla should be getting worried

I'm not exactly a Tesla fan, I think their cars are pretty bland, certainly the interior is pretty spartan for the price you're paying, and I'm not convinced of the entire infotainment system/massive screen in the middle.

But... Other manufacturers allowed Tesla to become an established brand, and right now if you tell someone you have an electric car, their response will be "oh a Tesla?" 9 out of 10.

On top of that, Tesla is learning quality/finish faster than other manufacturers are learning how to mass produce electric cars properly. The newer model 3 from one colleague is miles ahead build-quality-wise of the one from another, who got one of the first to arrive in Europe.

And lastly, Tesla has a massive head-start in battery production capacity, and I would not be surprised if they'd start selling batteries to other manufacturers soon. Battery supply chains are currently the limiting factors for many car models (the Hyundai Ioniq has a massive waiting list for this exact reason for example).

Most classic car brands also give priority to direct battery supply towards their more mass-market lineup where they're now offering hybrid solutions. They can make what - 10 hybrid cars with the same amount of batteries it takes to make a single-electric-one? Choosing between selling 1 or 10 cars limited by a strained supply chain is an easy choice. Sure they'll offer electric versions for a premium, but the hybrid-ones are the ones they're really producing and driving sales.
It's difficult to know what's better - some people may prefer to see posts, since they may want to find viral memes/videos/takes rather than to have to follow someone's output over time. It seems like a tradeoff to me - similar to short-term vs long-term. So it would be interesting for someone who loves news feeds to rethink them at some point.

I heard it described as similar to infectious Hepatitis A. Kids get it, carry it, transmit it, but they are asymptomatic. I haven't heard an age range, however. The thing that bothers me is that these facts are being presented in the mainstream, where it could go a very long way towards helping calm people (at least parents of young children). Or, maybe they have and I have just missed it.

I doubt it. Oracle has done a great job dissuading new business by suing customers for discussing benchmarks, suing customers for discussing security, auditing customers, jacking up prices, jacking up penalties, suing everyone else, etc... Plenty of reasons to drop already.

Note that there is a handy PeriodIndex version of pd.date_range:

pd.period_range(date_from, date_to, freq = "D")

AFAICT, a PeriodIndex and DateTimeIndex function mostly the same, and have many of the same methods, except...

* DateTimeIndex can't hold dates far in the future
* PeriodIndex can't easily round to the end of a period (e.g. date + 0*MonthEnd() errors)
* PeriodIndex doesn't handle timezones?
I can see your point. But if we are going meta... the discussion was going for quite some time exclusively between me and hef and though it got "heated" at one point, I didn't get the feeling that it was derailing at just some senseless uncivil exchange of insults. It is the kind of thing that can happen between a group of people talking at the bar, not just the internet.

Also, precisely due to this disconnect between what we write and how it can be perceived, it does seem helpful to me to occasionally have some curved ball thrown into the mix to help calibrate my sense of (a) where the other party is coming from and (b) check if the other party is willing to listen to you or just participate in a screaming match.
I in no way intended my comment to be seen as China bashing for its own sake, but in the early days of the epidemic in Wuhan, there were noted incidents of at least local officials claiming false information about how contagious COVID was and how far it had spread. It's difficult to generally trust any authoritarian regime that has a vested interest in downplaying things which in part worsened because of its own bad initial response but no, nothing right now gives a solid reason to doubt the current numbers on cases, fatalities, recoveries from China and if indeed they are true as they likely are, the reduction in new cases is visible, and even if that's being achieved through strict measures, it's heartening to see, because it shows that COVID spread can indeed be mitigated to some extent through social measures while medical resources brace themselves
That's an interesting point. I think that's a different sense of the word "anonymous," though.

There's a strict sense of the word "anonymous" that is from the tradition of writing: an anonymous letter, for example, or the sense in which 4chan users are anonymous. It means "this person has no unique identity at all, other than what one can infer from this written word." This is the kind of anonymity that e.g. Facebook has fought against with their policy that accounts should have real names.

There is another sense in which "anonymous" is used that is common to all kinds of secret societies, though, and that is simply public anonymity as a member of the society. You don't wear a pin or make it known that you are an active member, except maybe to specific individuals that have need of that knowledge. But within the society itself, you very much have a distinct identity.
Any chance you can explain some of the reasoning, even if it's a bit esoteric? One thing that's keeping me from going 100% IB is the lack of a transparently-stated fraud guarantee, like Schwab/Fidelity have. Other than that, IB seems like the best.

Textbook problems are usually short, with short solutions,
and demonstrating one specific rule. They are better handled by classical (rule-based) tools. Deep learning tools would either memorize them or resort to a rule based sub-module.

For integrals, solvability depends on the function set you work with. Since we use elementary functions on the real domain, a lot of integrals have no solution. We could have gone for a larger set (adding erf, the Fresnels, up to Liouvillian functions). This would mean more solvable cases.

As for the engineering distribution, no one knows what it is. The best we can do is to generate a broader training set, knowing that it will generalize better (this is the key takeaway of our appendix). BWD+IBP is a step in this direction, but to progress further, we need a better understanding of the problem space, and issues related to simplification. We are working on this now.
