Whether NoSQL is the best approach and whether DynamoDB is the best approach are two separate issues. I find DynamoDB too limiting with the way that it handles indexing, read and write capacity, etc. compared to traditional NoSQL databases like ElasticSearch and Mongo.

That being said, one advantage of DynamoDB is that it is API based and you can make a true serverless web app where all of the logic is on the client, you use Web Federation for authentication to DynamoDB, and you host your JavaScript files, html and CSS on S3.

Another advantage until two days ago, was that with most of the data stores on AWS, you kept your databases behind a VPC and if you used lambda, your lambda also had to be in a VPC and that increased warm up time for the lambda.

Now, there is the Read Only Data API for serverless Aurora. You don’t have to worry about the traditional connection pooling or being in a VPC.
They're not down 80%-90% within weeks. BTC has been on a year long decline from it's $19K peak this time last year. I'm not gullible, people are withdrawing USD using USDT. Thats a stable coin acting as advertised. I've never owned any Tether. But I've never seen so much FUD. Personally, I'm going to be getting some DAI as a stable coin as I like and trust it's decentralized system much better.
> Story points translate to cost. Customers determine the value. They examine the cost. And they determine whether the value is worth the cost. Is that 5 cent nail worth 5 cents or is it the nail that'll save the project?

There is absolutely no evidence that story points actually correspond to cost in a product organization (as opposed to a contracting billable hours situation), because the long-term scope of a project is unknown. When does a project actually "end" with respect to its cost vs value production? Is this accounted for via story points? Are all of those things known when starting the first iterations? I would submit the answers to these are "we have no clue."

Something that does however correspond to cost is well, cost. Team's have a known salary burn rate, and this is completely independent of how many imaginary points they make. Any organization whose value output is being measured where two weeks is actually such a large timeframe that it needs to be broken down into more granular estimates is 1) delusional about the predictability of their actual value output and 2) pipe fitters working on easy, well-known features.

There are many ways of estimating projects as a whole that are equally as (un-)reliable for estimation and take way less time, and these can be coupled together with financial rationalization from the business. If two week increments can't have significant variance for the business to make a profit, and this business is in the extraordinarily high margin software industry, they're working on the wrong problems.
Documentation may have helped, but any pilot that has used an autopilot should know how to deal with runaway trim.
Fighting any trim issue via yoke pressure is wrong, and flight instructors typically drill that into students.

Dealing with this is relatively simple:

1) Hold the trim wheel. Autopilots are designed so that humans can easily override just by holding the control.

2) Disable the autopilot / M.C.A.S. via switch.

3) Pull the circuit breaker. Even if they pull the wrong breaker(s), flying with a partial panel is safer than flying without controls.

Ask HN: Do you set goals?
Maybe it's just my own predisposition for not trusting/respecting the types of people who typically discuss goal-setting (i.e. psychologists, life coaches, etc.), but I've never been a big believer in capital-G "Goals." That's not to say that I'm not ambitious or motivated, I just don't see much value in setting them--following a checklist of goals seems like its own hell to me.

That being said, maybe I'm wrong. Perhaps setting goals could help me. Do you set goals and, if so, has it helped your life? Could you share some examples? Thanks!
an array of arrays is not necessarily contiguous in C(++). Indeed, if allocating on the heap, you end up with a bunch of discontiguous memory that's not necessarily correctly aligned.

A good tensor implementation accounts for strides that are SIMD compatible (eg; each dimension is a multiple of the SIMD register width).

I gotcha. I guess the confusion from my end is that I’ve yet to have a software development job where I wasn’t developing a product. No one in the orgs I’ve been a part of refer to the “product” team as the “product development” team. It’s just the product team, and the development team.

If that’s not been your experience then maybe you fall outside the target demographic of this article? I say that because it was super clear to me exactly what the author was talking about (in fact it even resonated with other members of my scrum team).

Alternatively, I suppose my experience could be anecdotal and not what most development teams encounter daily and struggle with.

"shot the attacker (apparently only once too, unlike in the USA where they empty their magazine)."
I am not sure if you have ever dealt with someone who is a lethal threat to you but it isn't like the movies. A wounded person can still shoot and kill you or stab you. You can put multiple bullets into a target and they can still kill you. Do police over react sometimes? Of course. If you have reached the point of actually firing a weapon at an individual you don't pause in between each individual shot to wait and see if you have done enough. Each shooting is different. If you think cops are leaving their houses with the intent or hopes of shooting and killing someone then you must not know any cops. They just want to make it home at the end of their shift.
The only claim I made about "driving the price up" was that local economic growth drove the value up. Ie, the productive value of the land increased because the local economy grew (this includes living, since everyone but remote workers have dependencies between home and work locations).

This isn't incompatible with supply and demand at all, and from your comment, you don't appear to have understood my comment at all.

Rust Language Cheat Sheet
Fortran produces efficient out-of-the-box code for dealing with multidimensional arrays. That said, most hand-written fortran doesn't compete with an optimized BLAS or tensor library using CPU-tuned intrinsics. For GPUs, hand-optimized libraries in CUDA rule and those are generally called from C++. Hence why you see deep learning generally in C++ (wrapped in python).

I guess it depends a lot on how much control they allow the offeree over the antenna, ground station configuration, and signal processing. Anyone that cares about the data quality they are getting from their satellites is not going to trust a 3rd party solution.

A wild thought - How much of this is caused by H1B visa restrictions and higher visa rejection rates? Dallas, and Texas in general, is home to the fourth largest Indian population in US.

I honestly don't know. I primarily work in Python professionally. Java before that. I guess of that list C# seems the most tolerable but I have the least experience with it.
I think Docker/containers make perfect sense in that they make portable software you can ship around.
The catch is: you have to really understand how the sausage is made to reason about building a proper container. Most people simply don’t really know what they are doing - they simply bash keys until it works. so the challenge of building new container images is usually more work for developers.
The person who was really proficient, this barely affects their day to day productivity - it just makes life easier when they go to distribute their app (or hand off to other teams).

The Anatomy of a Cryptocurrency Pump-And-Dump Scheme
Only to the American audience. Doubtful that it evokes the same association in Japan (www-sys-aics.riken.jp).
Ethically, I think not.
This reply borders on incoherent to me. What is best effort if not choosing the course of action you deem gives you the best chance to win? Exhausting yourself and risking a blunder in the final classical match just because other people want to see the spectacle of it? That doesn’t seem like “effort” at all.

Why do soccer players make back passes from offensive positions when tied 0-0? You think the coach gives a shit at that point if the crowd wants someone to give “effort” in a press, leaving exposed chances for a sudden counter-attack? Sometimes playing the back pass is the right “best effort” to be made.

Same with an intentional kneel to run out the clock before halftime instead of risking injury or a turnover on a last second play in American football. Or intentionally walking a home run hitter in baseball if you think you stand a great chance to strike out the next batter.

You seem to be conflating “best effort” with “intentionally disregard the strategy you deem best because a riskier course of action would be more appreciated by spectators.”
The interesting thing about ad fraud is the people that lose have no ability to police the problem. Ad networks get paid for fraud. Intelligent ad buyers that use cost-per-acquisition targeting, don't care because they just bid lower if the traffic is a mix of fraud.

The losers are unsophisticated ad buyers such as the brand advertisers that use ad agencies to fill their ads with garbage traffic. Proctor and Gamble has recently figured that internet display is pretty much worthless. The other losers are legit publishers. I am perfectly happy to pay $0.50 a click with half the traffic being fraud, as I am willing to pay $1.00 a click for legit traffic from legit publishers. I get the same result, buy my money gets split 50/50 between legit publishers and crooks.

I am mostly a dev, but have bought more than $1M in advertising on multiple platforms. The biggest joke I have ever seen was AppNexus. It was like 70% or more fraud, and it was the most obvious crap imaginable. For instance, all clicks coming from 8 month old user agents for evergreen browsers.

Google Adwords and Double Click have been mostly clean. I'd say 85-90%. I do see stuff that is obvious bullshit from time to time, and it goes away pretty quickly and but Google doesn't refund the money. I don't really care... they make it so we can police it pretty well. Facebook ads are completely clean, but they don't run a network.

The simple rule for picking a ad platform is: if it isn't loaded with performance advertisers (CPA), then stay the hell away.
I never said let's do nothing. I'm completely in favor of making hiring as blind as possible, especially to any physical and biological traits. I believe it's your stance that we should not do this.

Anyways, you didn't answer why people must be considered as groups instead of individuals? That seems to be the only lens you consider people, while also only choosing the group identity of the most perceived victimhood over an arbitrary time frame. And again, if you want to say that someone takes on the wrongs experienced by a group, then they must also take responsibility for the wrongs committed by the group. So in your example about US blacks, that group also commits the majority of crimes so they must acknowledge and resolve that too. Are you prepared to say that?

You're changing the argument into something about morality but the reality is that there is no cosmic justice. You can be born with missing limbs, or to a destitute family, or inside North Korea. The best we can do is make sure that if you work hard (and yes, harder than others who might be born to a billionaire US family) that you get the same exact chance to gain a position because you are actually competent and qualified for it, and what you look like and what some group in the past has done has absolutely nothing to do with that.
Right but you could also commit your changes to your model into a Git repo and use the "blockchain" that Git provides.

When people say blockchain the meaning that there is a distributed consensus comes into the picture. In this case, there is no reason for a distributed consensus on ordering or anything.

But if you are suggesting there are many text parsers that train the model, and there is a central modal that's held by the network state, sure. But I don't know what's the benefit to that as I don't think simply training on more text will allow this bot to produce better summaries.
Communication probably isn't the right word. The pilots are given the logs for all recent issues.

The prior flight called in a panpan distress signal for the exact same sensor failure and subsequently disabled the system to continue flying.

No one is really meant to communicate this to a commercial pilot, they're expected to read it themselves pre-flight.
There was no Constitutional right to carry a gun- or to own a gun- until 2005, and the 2005 Heller decision only covered keeping handguns in the home. Exactly how far the right extends beyond that is very much not settled law.

I was a research fellow part of the Missiplicity project and I worked on the feline cloning part of it.[1] I still remember protesters at Texas A&M and how our lab was in an anonymous outbuilding near the vet school and we had occasional threats from various groups and various talking heads pontificated as they were prone to do.

While gene edited children aren’t clones, the bioethics aspects aren’t much different. But, this too shall pass. A lot of hand wringing, then a Streisand type will have a gene edited child and all will be forgiven. (I mentioned Streisand because she had her dog cloned not long ago.)[2]

I can dig this.

That said, if a mechanic says “if you don’t get this repair your tailpipe is gonna fall off” and you say “nah let’s risk it”, you’re not gonna go back to him when it falls off and say “wow I can’t believe you let me drive my car until the tailpipe fell off, you should’ve done better!”

If, however, a dev team says “hey guys, if we don’t fix this tech debt we’re gonna run into some perf issues and the site may crash” it’s a lot more likely they’ll come back and still find a way to blame the dev team when the product inevitably does crash or really struggle to deliver results.

Again, like my other comments say, this could be completely anecdotal on my part and totally greener grass thinking on my part, but it definitely does feel like this is the way the product teams I’ve worked with behave toward development teams.

The arresting officers may not have been at fault but there's clearly something wrong with a system that keeps someone in jail for 3 months because of an inability to expeditiously conduct what amounts to some pretty basic chemical testing. Also, it is inexcusable to keep someone imprisoned for 2 weeks after the test in question reveals that the substance in question was not actually meth. Somewhere along the line there were clearly multiple failures with either the police and/or the prosecutor's office.
This is cool. Would not know where to begin with gut renovation in Japan, though. And some of these look quite weathered.

In US for example, you can typically sub-contract parts of the renovation to get decent pricing. One team for the basement flooring. One for waterproofing / sump pump installation. And then perhaps install drywall / paint DIY.

Of course this is aided by close availability to Home Depot, Lowes, and wide array of contractor grade materials and fixtures ;)
