Putting a high sticker price in front of someone is another one of those speed bumps to conversion. As the proprietor you'd probably prefer them to go for $70/yr, but $70 is a big difference as an impulse or low-deliberation purchase from $7. I'm the annual-plan-buying type, but I'm atypical in a bunch of ways - e.g., I live in a high cost-of-living area so while I'm not actually a money-disregarding rich person, my impulse-buy range goes a lot higher. (annual = 10x monthly is very commonplace)
So you can combine 4 modules to make a 72" 1080p display. Regardless of cost, this currently seems a bit impractical for home use.
As I'm in a similar boat to the OP, this is exactly why I'm hesitant to even interview with any of these companies, even as a test to see where I stand, simply because I fear I'd be blacklisted on some list these companies might share, should I bomb one without a lot of time spent reviewing.

I sometimes follow a Reddit sub geared for mostly recent CS grads. Every week or two will be a post from someone who got a FAANG job, detailing what he did in order to pass the interview. And some of these are pretty absurd - graduating last semester and since then spending 6 months going through leetcode 6 hours a day, studying algorithms, paying for interview training classes, etc.

And as an older guy who has a decent CS degree but hasn't needed to use 90% of anything related to algorithms in 15 years, I'd have to study a lot, and along with the numerous days of vacation time used for these interviews in California, it doesn't seem worth the effort.
Absolutely, it's easy to lose sight of it from such a vantage point.

No, you and joeyh are incorrect about the test (but correct about the result). As can be seen in the output, SHA1(bar)= f1d2d2f924e986ac86fdf7b36c94bcdf32beec15 but git_SHA1(bar) = 257cc5642cb1a054f08cc83f2d943e56fd3ebe99 . Why is there a difference? Not because of hardened SHA1. Hardened SHA1 essentially always produces identical outputs to SHA1

> git doesn't really use SHA-1 anymore, it uses Hardened-SHA-1 (they just so happen to produce the same outputs 99.99999999999...% of the time).[1]

https://stackoverflow.com/questions/10434326/hash-collision-...

There's essentially no chance that the string "foo\n" fell into that tiny probability of difference. The reason there's a difference is because before git hashes something, git will do various processing to it (maybe appending and prepending various things) and those things broke the carefully created collision. But a chosen-prefix attack might mean those various things can be accounted for, and a collision could still be found.

So we need to directly run hardened SHA1 on the data, which I believe is located at https://github.com/cr-marcstevens/sha1collisiondetection

As seen in https://github.com/git/git/blob/master/sha1dc_git.c

So I tested that one:

$ sha1collisiondetection-master/bin/sha1dcsum bar baz messageA messageB shattered-1.pdf shattered-2.pdf
f1d2d2f924e986ac86fdf7b36c94bcdf32beec15 bar

So it does protect against the new attack.

Out of curiosity, what sites did you have trouble with? I also switched to Firefox a year or two ago, and I haven't had anything noticeably break recently, so I'm curious if I'm just not going to the sites that have issues or if there's something else different in my config that solves it.
I think you're missing the point.

Cars represent freedom the same way a semitransparent American flag flapping in the wind superimposed over a bald eagle represents freedom, not the way a library card, bus pass, and a health insurance plan that lets you see out of network providers with a low deductable represent freedom. It's a symbol, not a practical increase in your ability to do stuff without constraint.

In many areas, guns are the same way. They're a symbol that represents freedom and independence to a lot of people.

When we formulate arguments in our worldviews and express these arguments to people with vastly different worldviews, it's worse than saying nothing. We sound crazy, out of touch, or malicious.
I haven’t needed to connect an iOS device to iTunes since iOS 5 in 2011.
The problem is that the dates are part of the document being signed.

Rather than keys, Alice will typically sign a document (e.g. an X.509 to-be-signed certificate)

Mallory creates two documents, the legitimate seeming document A (a to-be-signed certificate Alice willingly signs) and document B (the content of which is controlled by Mallory to an extent depending on the details of the collision). In document A I'm sure Alice will insist on the date being roughly correct so you'd detect that. But Alice never sees document B, she isn't aware it exists, so it can specify any date, including one chosen not to set off alarms.

For the Web PKI we were triply safe because:

1. We told Alice (the public CAs) never to sign anything at all with the dangerous algorithm after a set date. So long as Mallory wasn't able to develop and use a collision before that date and Alice did as she was told‡ this would be safe in perpetuity.

2. We already had a countermeasure in the documents, very early in each Web PKI X.509 certificate is the Serial Number, if you look at yours you'll notice it's a crazy huge number and seemingly not "serial" in any sense. It's random. Can't do a chosen prefix collision attack if you can't choose the prefix.

3. Since no more new documents were being signed clients in the Web PKI were able to stop recognising these signatures thus permanently ensuring the attack was impossible within about 18 months.

‡ A very small number of exceptions were explicitly granted, and a similarly small number of exceptional cases occurred for which no permission was asked. All investigated to everybody's satisfaction. As you may see if you poke around in the demo documents from this article, a collision document may not jump out as problematic from a crowd but it certainly isn't so innocuous as to survive careful scrutiny, and with such a small number of exceptions to look at this scrutiny was possible in a way it never would be for the wider Web PKI.
I guess this just seems pretty run of the mill (to me) for most statically typed languages. You import package "X" it does some meta-magic... et, voila! You get "dynamic" types because it does some fast compilation on the meta data it has and generates the method signatures, classes, et. al for you.

Honestly, I feel like this should be super cool and I'm just super missing something... but I don't know what right now.

I'm not disagreeing that different farming practices may be more sustainable. My argument is that existing farming practices are made more efficient and produce fewer emissions when using modern equipment vs. equipment that is 30-40 years old.

There is plenty of research to support your point, also another poster replied to this parent with an interesting paper. My assertion is supported by direct observation, that is, if we constrain ourselves to current industrial farming practices, there's plenty of data showing improved yields and reduced fuel consumption as more modern equipment is adopted.

I guess my point is that I don't see our relative assertions being in conflict.
I've made the unpopular argument in the past that when figuring the calculus on plans of lowering speed limits, you should consider added commute time as time subtracted from the individual driver's lives. Thus if the net time subtracted is greater than the loss of life from accidents, lowering the speed limit is the greater loss of life.

It's surely a slightly flippant argument, but I certainly think there's at least a little nugget of truth to it.
You'd be hard pressed to find a current cpu that would be the bottleneck in most AAA titles though. The Q6600 was released in 2006.
I live moderately. I don't wear jewelries, watches. All my clothes are from Uniqlo. I don't have expensive toys. I have mediocre gaming PC, my old Macbook pro laptop, an iPhone X, and a small set of electric guitar + few pedals + small amp. I have a small 29 gal aquarium. I live in a cheap area in NYC (Queens, nearby Flushing). I have monthly karate membership, and give regularly to my local church.

But I started my career late. I had three different unrelated degrees (no student debt thankfully, I attended public schools), jumping to different fields in my career. I also need to be ready to support my all-single/divorced-female old family members (aunt, mom, grandma). I also will probably have kids in two years.

So a FAANG salary would be nice.
I have to wonder what percentage of people are like me and Apple earbuds/AirPods have never fit their ears? Are my ears that strangely shaped? Most people seem to have no problem when I've never found a pair of Apple earbuds that can stay in my ear if I do anything other than sit completely still and upright. They just don't fit, at all in any way.

I have to use earbuds with a stiff silicone shroud that I can shove deep enough on my ear canal that they can't fall out. I couldn't even get the hard plastic Apple earbuds to balance in my ear, they just fell right out.

Right well, its clear that at least in java, he doesn't pre-allocate the size of the hashmap. Thus, when the hashmap hits its maximum size, of course the resize operation has to copy all of the data into a new map, which makes this no longer O(N) but something like O(NlogN) or O(N^2) depending.
Exactly. It’s only freedom if you have the choice to drive. If there’s no alternative for driving to go pickup groceries, pickup kids from schools and go to work, are you living in freedom? Have to pay insurance, get in a car that is more likely to kill you than any sickness, pay that same car to drive it, to store it, etc. It’s funny how I felt liberated after moving next to a subway station downtown. I now have the choice between 3 mode of transport, with all their benefits. I still drive but I’m not forced to anymore, that for me is freedom.
Not necessarily.

Regulatory capture is a thing. Regulators, at least in part, exist to maintain a barrier to entry for any new players trying to enter a field dominated by large players.

Several major tech companies only exist because they broke rules in their early days. And most people agree the outcome was a net benefit to society.

Let me get out the list...

>Before or after taxes?

>What year?

>Where did you live?

>What was your monthly rent?

>Did you rely on your family/friends for ANYTHING (including something as innocuous as "storing your childhood possessions")?

>Did you have any chronic or acute health issues?

>How far did you have to drive for work?

>Did you have friends or family you were obliged to support, even occasionally?

>Did you have a side hustle?

And so on.

Broadly-speaking, making $35k before taxes in 2020 in any major metropolitan area is a tightrope walk at best. The best way to encourage saving is to pay people enough money that they feel comfortable charting out a plan to save. That's a sliding scale, but I would say you hit 80% around the median wage, which is not $35k/yr.

IME the people giving this advice have a critical misunderstanding of either costs or the value of cash relative to when they started out.
That doesn't give the 70% the right to dictate to the 30% who don't live in cities how they should live. Nor do they need to. There's no reason why different environments can't address whatever problems they see in different ways. We don't need to force everyone to live the way people who live in cities live.
Markov chains are pretty smart - you've probably just trained yours more
Many languages with powerful macro systems can do the same. Still, it's cool/promising to see a .NET language capable of compile-time execution like this when they do not support macros in the same way that other languages do (but they do have plenty of reflection features and some codegen features as we see here).
Music support exists but needs a lot of love. Currently for my usecase (streaming my music to my Android phone) transcoding doesn't currently work (streaming flac over a mobile data connection is bad news) so I've fallen back to using dsub/gonic (subsonic compatible server) until transcoding is resolved.

It finds metadata pretty well (Artwork, artist info, and summaries) but playback leaves a fair bit to be desired and playlists aren't very well fleshed out.
This article seems to have tunnel vision on speed as the primary cause -- "Speed is what kills", it claims, and links to another page on their same blog that says:

> Speeding — defined as traveling too fast for conditions or in excess of the posted speed limits — contributes to nearly one-third of all roadway fatalities. This proportion has remained largely unchanged for decades.

They neglect to mention that, in America, alcohol contributes to about one-third of all roadway fatalities, too. In Norway, it's much rarer, due to stricter limits (.02 BAC!) and harsher penalties.

Big complex problems often have multiple contributing factors. Personally, I'd go after alcohol first. IME, nearly everyone on the road speeds, and apparently nearly everyone can do it safely. It's hard to argue that drunk driving can ever be done safely. The best "traffic calming" street designs in the world won't keep your city center safe from drunks.
Well I had a inspection I had to do last week. Equipment had to be out within two days. I was available on one day. So yes, Now. Not later. Now. Where's your public transport? Perhaps a van? No. Now.

I was referring to public transport rules and people's random car rules, eg Uber. But you want to enumerate toxic materials laws and assert I'm against that so you are Right and I'm Wrong in some attempt to show I'm completely unreasonable and probably kick puppies.

So, Obligatory note addendum to clarify so the internet feels safe:

- no, I'm not in favor of transporting unrestricted nuclear fuel in cars in icecream tubs in peoples laps while they speak on the phone and read the newspaper.

- yes I want freedom to have a vehicle of my own so that an odd shaped box that wont fit in a Uber can actually be moved.

- no that odd shaped box doesn't contain industrial waste. And no, I'm not an advocate for that.

- yes that box complies with standard size requirements. It does not stretch out the back like a jousting lance.

- having to clarify this stuff is bad. its like providing a legal document with so many clauses you forget the original point.

- And yes that guy is a helicopter parent to whatever degree.

- and yes, I've lost a family member to a road bicycle incident. The investigation showed that the only real way to have prevented that incident would have been to ban all road bikes. That seems unwise.
So then you take you car camping. Or just rent one for the weekend.

By all means, have a car if you want one. It just doesn't make sense for millions of people traveling the same direction at the same times 10 times a week for 40+ years to do it spaced 25'x10' apart. There just isn't enough room. Not to mention the environmental toll of spending 95% of your gas or any other energy source just to move the 3000lb+ hunk of natural resources you bring with you everywhere you go in life.
When speed limits are low enough, drivers don't care en masse.

In this article small towns are counted as ‘urban’, including areas with 2500 people. The main point of the article is the metric used to get 70% is not really what we think of as a urban city but anything from tiny towns to big cities. The real ‘city-folk’ number of downtown-dwellers is much much smaller, they suggest around half of total ‘urban’ dwellers.
The small visitor center at the Amazon Spheres in Seattle has a whole bunch of them.
The article just doesn't do itself a favor with its headline.

The useful point of the article is that the Scandinavian countries are so much less dependent on cars (and so much smaller) that you have years where no one dies by a car hitting pedestrian. But it do better pointing out the overall (considerable) quality of life benefit rather than the factoid - factoid arguments just raise people's hackles these days.

Overall, I feel pretty ambiguous about public transit or bikes vs. cars. I see the hypothetical appeal of public transit and bikes, but I think their respective proponents ignore a lot of the convenience of a personal automobile.

Is the 70% dictating to the 30% not the definition of democracy? They do have the right, but of course, that doesn't make it right. Further, the 70% who live in urban areas largely generate the money thats spent on the 30% living outside. Were interstates self-sufficient you may have had a stronger point.

Cars should probably be banned from urban centers entirely, replaced with investments in public transport, in walkability and in bikes. Cars outside the urban areas, well, it's not clear.

> freedom

Well a lot of people criticize our freedom to bear arms. People criticize free speech a lot. Despite what you've been told, freedom isn't held in high regard anywhere really. We just give it a lot of lip service.

> human rights

What is it? UN declaration of human rights originally had absolute "free speech". Then they started limiting it to protect religions, identity, etc. One human right is for free assembly and community. Another is for free movement. What happens when these "human rights" collide? Healthcare is a "human right". Should other nations invade the US to give us our "human rights"? Right to life is a human right? Should people who believe fetuses are persons invade to stop abortions? Things aren't as black and white as you think they are. Whose human right is more valuable?

> and democracy [representative government]

There are plenty of arguments against democracy. Go read about the founding fathers and their opinions of democracy. That hated the idea so much that they created a government to guard against democracy and only gave voting rights to a tiny fraction of the nation. The first presidential election ( for Washington ) had low single digit voting percentage.

Naively talking about "freedom, human rights, and democracy" sounds great at a superficial level, but when you get down to details, it isn't as straightforward and rosy as you think. The only people who talk about freedom, human rights, and democracy so cavalierly are those who never actually thought about it.

Frankly, the only thing "freedom, human rights, and democracy" has been used for in the past few decades is to use it to justify invading other countries. I'm sure all the millions of murdered vietnamese, iraqis, south americans, etc sure appreciate the "freedom, human rights, and democracy" we've dropped on them. It's pretty much a repackaged neocolonial "white man's burden".
The new rule only applies to debuts (e.g., you pull money from my account, rather than I push money to yours). See https://www.nacha.org/rules/supplementing-fraud-detection-st....

Most banks have some form of P2P transfer such as Zelle or Popmoney. If you want to pay a business, they push you toward a bill pay service that often mails a physical check.

My guess is that ACH cuts into fees earned from wire transfers. Additionally, giving everyone the ability to send funds to any other random account increases the bad outcomes of a login being compromised, or someone inputting the wrong account number.
Also, since this catastrophe happened because of systemic bad engineering practices how many of the other upgraded systems or software in Boeing airplanes should we trust?

"Cryptographic hash functions with output size of n bits usually have a collision resistance security level n/2 and preimage resistance level n."

Depending on what you're doing, "SHA-512/128" could have a 128-bit security level. But I guess it's safer to assume n/2 when making a general recommendation.
This has happened in every industry and in every time period. The mistake made in the article is that the author doesn't actually appear to realise how important this effect is (it is always amazing to me that you have all these people writing about the same topics, always from the same angle...no-one thinks to just open a book, and check what happened last time...actually I am aware of one book that has done this, just one). Again: every industry, every time period. It is permanent.

Definitely, you see new industries replacing old ones. Acknowledging the above isn't denying progress. But every industry consolidates down to a few large companies.
