Another unsubstantiated statement. How much market research have you done on PDF libraries?

Pricing is a sensitive topic and many factors play a role in it. Too many to be assessed by an armchair expert.

Don't you mean points, not inches?

That's why page dimensions are things like "/CropBox [0.0 0.0 595.27576 841.89001]". PDF points are the same as Postscript points, 1/72 of an inch, that is 25.4/72 mm. So those numbers mean a page 210mm wide and 297mm high: A4.
The way to see if something works in AWK is to read the 2004 Open group POSIX standard on it:

https://pubs.opengroup.org/onlinepubs/009695399/utilities/aw...

Here’s my AWK (OK, shell + AWK) one liner:

while echo -n '] ' ; do read a; awk 'BEGIN{print '"$a"'}' ; done

It’s a calculator; type in something like 2 + 2 and it will give you 4. Since standard AWK has advanced math functions like log, it’s a full blown scientific calculator.

The only tricky part is that you hit Ctrl + C (not Ctrl + D) to exit it.
Which makes a great point about how big Canada is compared to the US. We seem to misuse the term "America" to point only to one part of one of the Americas. Maybe it would be actually less confusing if we would refer to North America as the Canada continent? It would reduce the name conflicts by half and we would use as proxy the biggest country on the continent. There would also be the additional benefit of people not refering to Texas as "South America".
A friend of mine did this, in the legal way, with his wife and children. The police brutally beat him and he later died of complications associated with the beating.

Is there likely to be any meaningful difference? With most worthwhile SSDs incorporating a sizable DRAM cache and OS file system caching on top, would day-to-day journaling and other overhead be expected to make a dent in SSD longevity?
It feels like Apple product naming gets closer and closer to the confusion known from other manufacturers. Back then it was just the iPhone with an incrementing number afterwards. Now we get 2 different iPhone generations(8 and X) launched at the same time with a gap inbetween, and additional letter combinations afterwards with unknown meanings. What does XR mean and what XS? No idea, but those two letters cost extra.
I am not kidding. The website is unreachable for me from Poland.

>From my perspective a large proportion of people in the UK have at least one 4K TV, (unfortunately) most of which are 'smart'. Carrying apps for Netflix, Prime, BBC etc.

Having a 4K TV with Netflix won't give you 4K Netflix. You need to actually pay extra for it, about a third more.
Wow, that looks really cool. From https://github.com/e1ven/Robohash it looks like there are dozens of components (mouth, nose, etc.) that can be combinatorically assembled, each of which has been hand-drawn, which must've taken a great deal of work on the author's part!

Track your sense of smell during Covid-19 and beyond
About 6 weeks ago, I had a cold. I didn't think much about it, because at that time the virus wasn't supposed to have arrived here (reports started a week later). I had a dry cough initially, chills on two nights, but without fever, and some light trouble of breathing, which isn't that unusual for me in Winter and I blamed on my allergic asthma.
However, when it was mostly over, I noticed that I wasn't able to smell my daughter's dirty diapers. Usually I am pretty good at smelling her even if she's in another room, but I smelled absolutely nothing, even when changing the diaper. That was long before I read the first reports of anosmia. Ever since I wonder whether I already got it.. I guess I will never know..

Yep! That's what really makes influenza special, as I said the mutation rates are only part of why Influenza viruses rapidly change. Their ability to cross between species by combining easily with other types of influenza viruses are the key to their incredible variability

One of the distinguishing trait of CoVs are their special RNA replication/transcription mechanisms that results in less errors, which is really important considering the large size of their genomes compared to other RNA based viruses. Though, and correct me if I'm wrong, aren't they still extremely less stable than DNA viruses? Which is why only short/medium term immunity is usually possible? I don't know a lot about the synthesis of coronavirus RNA but it looks super interesting

Sorry. When you said "really proud" and "so great", it was perhaps an emotive choice of words.

In the end the semantics of CTEs should be much the same throughout. There may be small differences, and perhaps larger ones such as being able to update through a CTE, something like

with x as (...)
update x set ...

I don't know if PG supprts this, and it wouldn't break my heart if it didn't. It would be easy to work around.

Also IIRC PG has 'materialized' and 'recursive' keywords. No biggie.

So the semantics are substantially the same. Difference is, how the optimiser treats it. That means you will get the same results back but the time difference may be enormous. This explains it: https://paquier.xyz/postgresql-2/postgres-12-with-materializ...

In my previous work, the predicate pushdown (which is the posh term for the optimiser rewriting the query as the above link demonstrates) made CTEs usable. Without them, performance would have destroyed the company.

Can we get round it? Mostly, yes, but it would have been more work for us (meaning more human hours) which the DB optimiser should have saved us from.

The only unique thing CTEs bring to the party is recursion. Otherwise they are no more than a convenience, albeit a great one.

HTH

EDIT: MSSQL has a good optimiser when it works. I recently wrote a trivial CTE and had it take a minute to run, WTF? Looked at the query plan, something was very wrong there, pulled out the CTE part and put it into a temp table, ran in one second. 60x speedup. No idea why, was not impressed though.
my understanding (see references in linked page) is that when one does what you said and compare placebo to “nothing”, almost the entire effect goes away.
Uncle Bob is overrated. He's the personal embodiment of the "for dummies" series of the industry. Quick to say what everything should look like, he's given many people a false sense of direction by making no mention of all the reasons why something shouldn't look like that. If you're reading Uncle Bob material and not scratching your head a bit thinking "are you sure that's right?", do yourself a favor and go find some Fowler material instead.

All You Need to Know About Cyber Insurance Coverage
Can this be made to work if the `id` and `duration` are in different tables (with a joining key)?
A theory i have heard from someone in the hedge fund industry is that this use of "alternative data" is mostly marketing. Investors go to hedge funds for their genius high-alpha proprietary strategies. If you can honestly say that you are feeding tracking of honeybee movements into your model, that makes you seem like far-out geniuses with loads of alpha, so you will attract more investors. For a hedge fund, attracting investors is more important than actually doing good trades.

Of course, nobody will say this out loud.

This is not to say there are not some genuine users of alt data. Of course there are! But it's not happening at the scale that everyone wants to believe.

This is a very similar story to the whole "big data" thing in Main Street businesses.

It says that Safari 13.0.4 (macOS) and earlier is required to reproduce; Safari 13.1 was released last week, so if you’re allowing macOS to stay up to date, you’re okay there. I didn’t see a clear answer for iOS, but if they published, it has likely been fixed in iOS as well (or else they’d miss out on a $75k bounty).

Ask HN: How much do you pay for Google Cloud?
I migrated to GCP a couple months ago, and I love it. Super convenient, great services.

But boy oh boy, every time I check that billing tab it gives me a mini heart attack. I am scared to look anymore, the damn thing gives me anxiety.

I got two Kubernetes clusters with small instances for two of my side projects, and a VM for automation stuff.

One month the forecasted cost was over $800 ... I panicked, I cut as many corners as possible. This month I got an invoice for $250+ ... which is manageable I guess, but the forecasted amount for April is around $450... Come. On. Google, you're killing me here.

So, I guess what I'm trying to find out is how much do you guys pay for Google Cloud and how are you keeping your cost under control?

Oracle is currently moving in the direction of autonomous databases. It's no longer just about having great automation features but about the database being able to do things for you like create or drop an index in order to improve ETL performance, and it's all done autonomously.

>30% of Netflix subscribers were on the "Premium" tier [1], which is the only tier that offers 4K.

Here the best tier is actually called the "Family" tier. Seems to suggest that the real value proposition for the 33% price increase is not 4K over 1080p, but rather being able to watch four streams at a time instead of two.
All of the above, plus -

A senior engineer sees the big picture more readily, and understands the negative as well as positive impact of a change.

In any decision there's seldom one "absolutely right way". Usually it's a case of which compromises are the easiest to live with. Being able to see "both sides" and being able to see beyond the immediate is a key attribute.

Here's a hypothetical example - a Junior programmer wants to switch the development team to using Linux, because "there are lots of advantages to doing this". A good senior would ask the question - "ok, tell me why we _shouldn't_ switch?". There are, of course, disadvantages to switching (just like there are advantages and disadvantages to any decision). To show that you understand _both_ sides of the decision is critical. It's not enough just to know the positives, you have to understand the negatives as well.

In my experience you will get all kinds of advice to "absolutely do this". But when quizzed the reasons for _not_ doing something have not received the same level of thought. Folks who can see the big picture, and see the long-term impact of a decision, make better decisions.

[Of course the junior may be right, in the sense that it may be a good thing to switch. the outcome of the decision is not my point, it's the consideration process that I see as a differentiating factor.]

It may have been a poetic way to describe the feeling some people have that while we are alive, we are not doing the things that make a life, so to speak.

I don't know how to put it succinctly, but a single comment on HN months ago described the feeling. Is it true? I don't know, I don't have "myself but living as a thousand years ago" to compare. We do know that people's social circles, e.g. the number of close friends people describe themselves as having, has been shrinking.

The Screen and the Job have displaced almost everything else is our lives. Loneliness is just a primary symptom.

The Screen, whether it’s TV, computer, or phone, has supplanted almost all social interactions. This manifests itself in things like SitComs on TV (just a bunch of friends or family hanging out) or Social Media on phones. It’s very easy to fill the social needs of right now with a Screen. But under even a minuscule amount of self reflection these are revealed as hollow substitutes for real human interaction.

The Job has completely taken over as a driving force in evaluating choices. The average person has to consider all options in the light of both the current employer and the specter of tomorrow’s. Moving across the country for a high paying job? Great! Moving to be closer to friends? That’s a career killer.

No wonder we are lonely. We make choices in the short term that optimize happiness, often at the expense of our relationships. Ghosting is not just for dates now. Then turn around and make choices in the long term that optimize employability at the expense of all else.

That's a straw man. Actual attitude is "Whatever is predicated upon breaking the known and well-established laws of physics must be mumbo jumbo".

Reiki's purported mechanism of action fits that description, although it might have some effect through psychological mechanism, as does placebo.

A and B are on a phone call. A starts a video meeting. B goes to shortlink.dtmf or opens the app, which starts listening. A clicks "transmit room code" which goes over the existing phone connection. B's client hears the signal, decodes it, and gives them a link to join.
Can this be used as an alternative to Kurento? I use an ffmpeg command to send an RTP stream to Kurento which then broadcasts that to all clients that connect via WebRTC. I've had to rewrite the code that interacts with Kurento twice already. It doesn't feel like a rock solid solution. e.g. when you accidentally switch audio and video ports in the ffmpeg command the entire kurento instance crashes. I can't expose Kurento to untrusted instances otherwise there is a risk of DOS. I don't feel like running a whole Kurento instance per ffmpeg command is a sustainable solution.

It might not be obvious but I am not using WebRTC for video conferencing. My use case is basically regular live streaming but with latencies in the 100ms range.
