"And yet a great many of our institutions are set up to discourage, distract, destroy and derail the making of anything."

This may not be obvious to everyone writing software. Or maybe authors today just do not care. They are too busy chasing users.

As for the later some who would call themselves "hackers", I wonder: Did the original "hackers" from whence the term was taken have such ambivalence and accept what was made for them (including "platforms") fully knowing that it meant lock-in?

Thwarting "hackers" from making things for themselves may not always be obvious today because in fact some of these "institutions" are set up by organizations who desperately need developer contributions.

As long as they can take the contributions and use them to generate revenue or mindshare for the organization, they appear to be encouraging people to make things... but only if authors agree to jump through hoop after hoop.

"Instituition": Want access to our pool of end users? Jump!

Today's so-called "hacker": How high?

But what if the "hacker" does not plan to share his program with end users? What if he is writing it only for himself?

What is the purpose of making such an author jump through any hoops? How does that serve the author in any way?
Nah, it's cool. Cheers, bye.

When I was growing up, I was always very skinny. Now I take Remeron (Mirtazapine) and have gained about 20% (19 kg / 40 lbs) over baseline (90 kg / 200 lbs), although I also stopped working out as much due to lifestyle changes. Now take Metformin for both weight loss and possible life-extension. I also cut out carbonated diet beverages after their links to increased hunger.

I'm on a mission now to increase activity to help with ghrelin and leptin levels.

Is deterministic, so—

I still need to write the last two lines. Ideally “stochastic” will make its way in there; it can fit the metre.
Actually the first example looks perfectly reasonable to me. I would have used changes of "if () return" instead of a huge OR, but the result would have been the same.

The second example I can't judge. Probalby the variable name is bad, but not extraordinarily so. It's a lookup table, I can't tell if it is a good or bad idea without know what is being looked up.
That's surprising. Mr. Robot has the most realistic depiction of hacking I have seen in mainstream media.

We started deploying our Kafka cluster as a set of N EC2 instances but we started running into a bunch of issues (rolling the cluster, rolling an instance without moving partitions around, moving partitions around, etc...)

Now we run Kafka through ECS and wrote some tooling to manage rolling the cluster and replacing brokers. krollout(1) (currently private) basically prevents partitions from becoming unavailable while rolling.

Now that multiple teams are using Kakfa we started exploring how to scale up. Each team may have different requirements and isolation can become an issue. Likely more tooling will need to be built around this.
California’s Tough Bar Exam, Long a Point of Pride, Faces Pushback
IANARS but this plane should give the remaining stage(s) four advantages:

1. +230m/s orbital velocity [1]

2. +9km launch altitude [1]

3. can launch in more weather conditions

4. 1st stage can abort mid-launch without loss of payload.

Of these, the most important is the increase in launch altitude, because that means stage 2 launches in air of greatly decreased density, leading to the following efficiencies:

A. a vacuum-optimized nozzle can be used, increasing engine performance

B. less aerodynamic/drag energy losses

C. max Q should be lower, allowing full throttle usage, reducing mass needed for structural elements, and reducing vibration stresses on payload

And how many people are aware that it is possible and that it is for their benefit to do that?
Err... you're responding to someone who very clearly said they hit a (serious for them) bug which needs fixing. That's definitely not a feature proposal. :D
Being resistant to common misuses is indeed a feature in real world cryptography. We saw that with DSA where you leak the private key if you happen to reuse a nonce; yes, you shouldn't do that, but it's better to choose an algorithm that doesn't suffer from this in the first place.

I'm not rooting for SHA-3; I'm just saying that it's wrong to dismiss length extension attacks only because they're commonly effective agains misuses of hash functions.
I was thinking this would be a great application for Blockchain technology.
People (rightfully) pointing out that Siri sucks compared to competitors should realize that Apple is making a very serious tradeoff in favor of privacy.

It's a huge handicap when you're only allowed to train models on device using just one user's data, or only allowed to use various complicated privacy preserving training methods (I'm not talking about taking a user's data, removing the obviously identifying fields and sending it to the server, which does not really preserve privacy except for simple statistics). There's no way Apple can train the same super complicated deep learning models that Google uses, for example, when Apple can't just gobble up all their users' data. And all of the "provably" private methods for training models incur significant accuracy penalties.

So it's a little rich that users on HN will complain about Siri on one hand, and on the other hand complain about losing privacy.

In the end I think this is a fatal mistake for Apple: people love to complain about privacy, but time and time again reveal through their purchasing choices that they don't actually care, especially when there's usability tradeoffs. Apple would be better off vacuuming up all their users' data if they don't want to be crushed by Google/Amazon.
Most comprehensive data on greenhouse gases published so far
Have you ever looked at any proprietary solutions like Google's PubSub? We're running on PubSub for over year now and outside of some unplanned downtimes it's scaling very well. But as we're looking to branch out out of GCP we are looking at Kafka as an alternative.

Could you comment on particular problems and challenges that you ran into?

For the context, we're currently sending around 60k messages/sec and around 1k of them contains data larger than 10kb.
Strongly seconding this. Finding Brave on Android was a huge moment for me. The mobile web is downright unusable on Chrome in Android and there are no good non-root options for ad blocking.

Firefox is dog slow (sorry FF), Opera crashes on me regularly, and I don't really trust any of the other 3rd party browsers.

Brave is basically Chrome with ad blocking.

while Galileo was far too good at choosing the experimental setup that would give him the answer he wanted, while ignoring any such setup that would prove him wrong

By this you mean that he was good at designing experiments that were sensitive to the basic physics of what was going on, while being insensitive to confounding factors?
These are great suggestions, but they beg the question of how do we achieve some form of limited direct democracy?
> maybe internet and mobile innovation have peaked?

In my observation that notion gets thrown around in large batches about every 3 to 5 years consistently over the last 20+ years re the Internet & Web. Then crypto currencies take off. Or mobile via smartphones hits. Or ecommerce takes off. Or social takes off. Or search gets drastically better and good content becomes easier to find, spurring a boom in its creation. Or SaaS takes over. Or streaming media starts crushing old media in tv, movies, music, etc. - ten years ago Netflix was a $1 billion market cap DVD distributor and Spotify barely existed. Or cloud computing - and thousands of follow-on services - finally becomes cost effective & accessible, then everyone moves to adopt it. And then AI becomes cheap, accessible, and distributed everywhere. And then...

Internet & mobile innovation is in fact about to accelerate.

But mostly the counter would just tell you to pack your bags and get lost whatever you said.

Full access (read and write) to the PowerDNS HTTP API requires one of their generic SQL backends (via https://docs.powerdns.com/md/httpapi/README/), such as MySQL. The bind backend only supports reading from the API, changes to zones would need to be done on the file system and/or using pdns_control. Beyond that having all our records queryable via SQL has been nice for debugging and researching our own DNS records, types and etc. Lastly, backends like the MySQL one allow for things like auto generating serials and adding comments to the DNS data.

assuming an epstein drive is possible yeah it opens up more or less direct brachistochrone trajectories between here and mars. Just wait until the planets align and burn.
Important to note that night glider mode is dependent on the rotation of the overall space station, so that you can set the orientation of the panels to be edge-on into the wind once and have the overall rotation keep that orientation indefinitely. Without the rotation, you'd have to continuously use the motors to adjust the panels, which would burn them out more quickly, use more power, and since they likely aren't freely rotating, would cause large spikes in air resistance once per orbit when you hit the limit of travel and have to do a large opposite rotation to maintain edge-on orientation.
I see, thank you. Can't NSQ do that, or at least get probabilistically close to it with multiple nodes (i.e. doesn't having more nodes reduce the probability of data loss)?

It labor's like 80% of marginal costs 1/4 of it would be tremendous profit margins matched by exceptions like google and pharma. You can see why I'm probing. Can you disclose the typical industry margin?

Are your costs Hawaii costs as the username suggests?
It wasn't only basic spaceflight. It was basic physics in general. Like when the two protagonists are somehow hanging off the ISS and Clooney has to let go because Bullock can't pull him in. It's a huge important moment plot wise and is really really dumb physics. I still don't even know what the filmmakers mistakenly thought could pull on them in that situation.
Avoiding Third-Party UI Libraries on iOS
There are a number of different causes for the slowdown. I'd argue the slowdown was caused in large part as a reaction to the chaos and violence of the 1960s. Desire for safety -> more regulations & less investment in new things. I don't know that any specific law or rule can be attributed to the slowdown or its start.
Incidentally, Japan's maglev project (unlike their ordinary trains) is being done at ridiculous costs and ridiculous timeframes ($80 billion USD spent over 31 years -- 2014-2045 see https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen). Seems like the technology is very tricky and 90% of it will have to be built in tunnel.

They can support this because their ordinary transit infrastructure is built out already, the Tokaido high-speed line is at capacity (trains every 5 minutes at peak hours)! Effectively, they have the money and they've run out of more reasonably scaled infrastructure projects to build.
Right. Reducing the delta-v by a constant amount reduces the fuel requirements by a specific percentage. The correct thing to measure delta-v savings to isn't the launch requirements, but rocket exhaust speed. That is, if your rocket exhaust speed is 1 km/s, saving a km/s of delta-v will reduce your fuel requirements by a factor of 2.718

Great question @vividjoy.

First up, we work with licensed caterers and restaurant kitchens to ensure the food production kitchen is safe from a food safety perspective.

Secondly, we curate and personally taste each individual menu to ensure a high quality experience in terms of taste.

Thirdly, we transport all the food cold to ensure that it maintains its quality and consistency a lot better. We provide detailed heat and serve instructions so you can create the most authentic experience.

We'd love for you to try it out!
Japanese zoning restrictions also contribute heavily here. It's not just that higher-density residences are available, it's that you can put them nearly anywhere. According to http://urbankchoze.blogspot.ca/2014/04/japanese-zoning.html, not only are there vastly fewer zones (12, nationally), Japanese zoning laws specify only the "maximum use", instead of exclusive uses. So anything zoned for commercial use, for example, could also have neighborhood stores and residential.
Do you have any actual examples? I googled your suggested term and found a bunch of people outside the US(lots in China a few in the UK, one in Canada) and a bunch of others who wouldn't qualify as accredited investors.

The great depression started before the SEC existed and was a completely different world.

Back to my original question I asked if it was easy to find examples. I have no doubt that you can find a few since fraud happens. But I think you'll find it difficult to find more than a handful.
Sounds like a "no free lunch" theorem for molecular evolution.

It seems unlikely you could guarantee that the bacteria could never evolve a way around all the linked attacks, but maybe by making the most obvious solution to one of the attacks be exactly the thing that makes it vulnerable to the other attacks, you could make the hill to climb much steeper.

Extremely clever antibiotic engineering: experimentally determine the most common adaptations that protect against your antibiotic, and incorporate countermeasures to those adaptations in the antibiotic.
Yes I'm aware sorry was on transport so wrote a short reply. What I was relating to was Open 'Cloud' platforms and the presence of RedHat and their support / contributions.
I've seen it mentioned at times, usually in discussions around Minecraft or Dwarf Fortress. Factorio definitely scratches a geek itch, but KSP has one advantage - Spaaaaaaaaaaaaaaceeee!
Not so much, there's no competition, so it's easier to track. I used to collect freflies in a jar as a kid. Seems like a similar idea to schools of fish, herds of antelope, etc. Stay together (even if defenseless) and predators have a hard time picking an individual to hunt.
I don't see why you would've expected it, it's not like any of those things are particularly trendy.
No answer to 1. I have no idea what brave's plans are. I can conceive of a locked down ad platform, both whether that would be acceptable to advertisers and worth the tech investment is debatable.

On 2, normal market dynamics. If tokens get hoarded, that increases the value of the remaining tokens. I assume that tokens can be split into arbitrarily small fragments.

There's also nothing stopping Brave from issuing more tokens (either indistinguishable from the original tokens, or a new type of token which is handled in the same way)
Skylake now GA on GCE
It just doesn't support Allo yet. Try SMS then.
NLP quality is dependent on ASR quality (automated speech recognition, transforming audio into words) because you can't generally get meaning without words.

ASR quality is dependent on audio quality (plus, of course, a bunch of big-data-driven training) because it's harder to get the words right if you can't hear the sound.

Audio quality is dependent on microphone(s) quality and signal processing (higher signal-to-noise ratio).

And getting that to happen at far-field distances of 10-20 feet in noisy environments is not easy.

So... bottom line: the better the microphones, the higher the ceiling is on NLP performance.

Ah, the paradox of choice (Firefly Edition).
Arguably, we don't. The people who are currently supported by representative democracy wouldn't like that to happen. Having direct democracy with instant recall of delegates will likely not be accomplished any time soon, due to "the powers that be" lobbying against it. And if it ever were to succeed, they'd up the advertising game to mislead and misinform people more than is already done.

Perhaps I am cynical, but I do not believe that a system which benefits the average person, the vast majority, can be accomplished in a system where the profit motive exists which is in most cases a direct contravention to the long-term wills of humanity, that is, our safe continued existence, and maintaining a relatively free way of life.

Edit: also worth looking at what has happened with previous campaigns to make the voting system fairer; in the the UK, the alternative vote referendum was opposed by those parties which drew large gains from FPTP, namely the Conservative Party. Their website compared the AV to a system in which your child wins an egg and spoon race, but he isn't given the trophy.
About cars this is absolutely not true, cars can and have been built by a handful of people in just a few days. Ever heard of Open Source Ecology?
Speed isn't a black-and-white panacea property, cost of brute-forcing (ram, cpu, time and money) and other attacks should also be prioritized for a given use-case (ie argon2, scrypt). Fixating on a single, fast algorithm and making it a near universal monoculture makes it easier for well-funded state and corporate entities to reduce their costs to generate a hash collison or do something else nasty because they only have to invest in one kind of possibly cheaper/simpler ASIC building-block.

Having several different, but throughly sensible algorithms who's strengths, weaknesses and limitations are well known is a better approach than saying "everyone use X" a-la NESSIE. Users with Paradox of Choice going on can pick the lunch special, AES.
According to (IIRC) the film's science adviser, the intent of that scene is that they are still decelerating relative to the station on the chute they are snagged on, and Clooney's charscter believes that the line doesn't hace sufficient strength and may snap with both of them but will hold with just Bullock's character.

If that's not just a post hoc rationalization, the film certainly doesn't seem to convey that effectively, though.
Parable of the polygons is extremely questionable. For one, it attempts to have its cake while eating it too, by pretending it's an abstract demonstration about choices while explicitly calling out to hot topics in diversity, implying a clear causal link. For another, the model involves discrete agents on a discrete grid making decisions based on their immediate 8 square neighborhood, with no persistence or hysteresis, which does not at all match the real life domain it is attempting to model.

If you changed the grid geometry, changed the action radius, or added a more complicated decision mechanism, it is likely to result in a completely different outcome. It is more like a cellular automaton than a sociological model, compounding design choices, not agent choices.

It should probably be called Parable of the Quantization Error instead and held up as an example of an explorable explanation being misused for propaganda purposes, using its medium to present a false image of impartiality.
Here's a chart of the difficulty history. Difficulty at the start of 2010 was 1. Just one. By 2011 it was 18K, by 2012 it was up to a million, and by 2014 it was a billion.

In early 2010 it would still have been CPU mining. I couldn't find exactly when GPU mining started, but it wasn't available at first.

There were no mining pools yet either, so if he successfully mined any blocks he got a full 50 BTC each time, or over $100,000 per block.

So he should probably keep looking for his old file.
