It makes me think of the Acquion project from Pittsburgh (http://aquionenergy.com/). That was an interesting attempt to commercialize environmentally safe batteries intended for uses where low power density isn't a problem-- eg underground energy storage for windfarms or solar arrays. They went bankrupt a couple years ago, but the concept was really exciting.

The immediate technical challenge with these kind of batteries at scale is the electronics to monitor and maintain the battery banks as well as deploying these things. It would take a truckload to set-up something usable for a house, I think.

I have the same issue on Chrome on Android and I always reload the page (not the Twitter reload button), which always seem to work for me. I don't know if they do this on purpose, but it does make you wonder. I do not want the Twitter-app on my phone.

Fair question. Not a humble brag, no.

I guess I'm trying to understand what the modern IT office looks like. I have close to 20 years of experience and used to do things a certain way and accountability - of my own tasks and keeping my boss accountable as well - is high on my list of values.

When I changed jobs I'm now confronted with a new environment where people do things differently, which is totally fair.

But I don't believe working on top of other people's tasks without talking to them first is a good practice. To be honest I think it's quite rude.

That's what prompted me to ask this question. What are people doing? Do you use PR's? Do you commit on other peoples PR's? Do you talk to people? Is everything nowadays that Slack is the norm and talking is overrated?
I get the limit in Android with both Chrome and Firefox. All the time.
Thanks for your efforts! Actually, despite ArchiveTeam's statement of having captured 98.6% of public profiles, I wasn't able to find a single post (let alone a complete list of posts) of a single person I cared about on the Wayback Machine as a result of the last-minute scraping (there were a few that had been crawled earlier): neither any of my friends, nor people like Timothy Gowers, Terence Tao, John Baez, Linus Torvalds, etc. I just assumed it had somehow not been uploaded to the Wayback Machine yet, but if it's gone... oh well. Such is life. Thanks again anyway!

Lifting Firming Cream
These agents are only truly effective if you are trying to lighten the pigment of a large area of the skin. The chemicals tend to spread out, so it is nearly impossible for you to use them on a discolored area as small as an age spot typically is. What usually ends up happening is that the skin surrounding the spot becomes lightened as well, which leaves the hyperpigmentation still visible and throws the surrounding area out of balance with the rest of the skin.

The best age spot removers do not contain these bleaching agents, or any other chemicals because these substances will hurt you internally. The chemicals commonly used to make skin care products have been clinically proven to build up in the soft tissue of the body, where over time they cause the onset of such maladies as organ toxicity, nervous system dysfunction, and cancer.

Even though they are scarce, it is well worth your time to seek out those products that contain only natural compounds in them. Plant based compounds offer you everything that you need in order for your skin to be healthy. Of these ingredients, the best age spot remover is a compound known as Extrapone nutgrass root extract, which is a potent melanin inhibitor.

This extract is used to develop the best age spot removers, because not only will it blend your dark spots back in with the rest of your skin, but it will also balance your entire complexion as well as prevent new age spots from forming. If effectively ridding your skin of these melanin spots is your goal, then Extrapone nutgrass root extract is the answer that you have been looking for.

26-year-old billionaire is building virtual border walls – government is buying
Generally short-sighted politics gets in the way in the UK based on my own opinion. Support/budgets/etc get withdrawn at precisely the wrong moment (and usually for some petty point-scoring or if ministers are running scared from the media/opposition)

Its happening right now too with electric cars and solar electricity - solar has generally been seen as a success with a lot of installations taking us to 3rd place in Europe for solar megawatts despite there being essentially no sun (1), and EV cars are starting to become something actually viable for most people's lives. The government has just announced that the UK is now legally bound to be carbon neutral by 2050... yet the government chose also to revoke funding and support for both solar and EVs and so subsequently update has plummeted (2, 3) right at this vital point.

You’re gonna have to explain what on earth you could possibly mean by that. Citizens and non-citizens have equal rights under the US justice system. Awaiting trial sucks for anybody, there’s no reason to give any class of people special entitlements.
I really don't understand how.

Ireland doesn't require ID either. You could visit Dublin on the ferry from England showing no papers other than your ferry ticket, bought for cash as you walked on to the boat, and I'm pretty sure vice versa. Even when there were the armed checkpoints between North and South. Did this quite a few times. I see no significant support for an "Iexit", so it can't be connected with ID, or attitudes to it, but the disingenuous politicians and right of centre British media stories on the EU. Murdoch et al.

As far as I know no EU citizens were required to have additional identity requirements, or present anything for NHS treatment, until the actions of the current and previous Tory governments. Which I found offensive in the extreme. FWIW I voted remain.

If I travel to a country in the EU or elsewhere that requires ID, I carry ID. I'd have my passport anyway. I might wish they had a similar attitude to ID, for the reasons stated.
I try to explain that to people. Even just the basics like fiddling with your EQ to your liking.

A lot of this analogue woo applies to synthesisers, as mentioned previously. For £500ish you can buy a million core, trillion transistor monster but for £1500 you get a box with some op amps and a (gasp) digital signal path in some cases.
Yes, although ARM came out of that and now look at that (...or your smartphone) so its not all a disaster.

The Raspberry Pi is a spiritual successor which I am generally pleased to see. The RPi was I think partly responsible for a real Computer Science curriculum getting back into schools ... I hate to say it but I think it was Michael Gove that made this happen!
How many people do you estimate died unnecessarily under Mao?
I always thought it was a bit crazy to let the client control the computational complexity of a query (to a certain degree) as it makes query optimization really difficult.

A few years back I designed a REST API and made the mistake of allowing too many query parameters, which made it really hard to optimize the database as there were hundreds of possible filter combinations (some requiring joins) that a client could ask for and that needed to be covered with indexes, so while most of the common queries worked well some of the "long tail" queries would always run into timeouts.

When using GraphQL with a backend like Hasura that generates SQL queries I would think that you have the same problem for complex data models, as there will be countless combinations of filters and joins that your database would need to efficiently cover. From what I understand most organizations solve this by either restricting the types of queries you can make through GraphQL or by just defining timeouts and dropping queries that take too long (which does not offer a great user experience).

To all of you who use GraphQL in practice, how do you solve this issue?
I'm using Julia the same way for math computation: starting as a scripting language, but creating new types and adding typing information on the fly (start with a tuple, then create a struct if that tuple is useful multiple times).
Yep. At this point in time they should have plenty of test cases and regression tests which should catch such situations. While Boeing may feel they are doing a lot of testing in the simulator - there are way fewer simulators staffed with test pilots than there are 737 MAX out there. When such errors surface at this time in manual testing it calls into question the development process. And a lot of the trust - aka. certification - is based on that process.

As I have mentioned here before: The angle of attack sensor was never intended for the purpose it is now used for - military aircraft may do such things but not as an afterthought and not connected with a control surface which has a lot of delay (trim wheel winding. Delay is a major factor in destabilizing control loops). Equivalent sensors are the airspeed pitot tubes but they are a much more robust concept. Even they have brought down airplanes. We lack sufficient real world (heat, humidity, snow) information about the quality of the sensor data even before it may get distorted by transmission and processing on its way to the control law. Cleaning and validating sensor data is tricky under the best of circumstances. It does not sound like they have a handle on it.

Hi Boeing, what real world data from mounted angle of attack sensors have you analyzed? Why do you believe this data sufficiently represents climate zones and flight conditions (take-off, landing, turbulence, malfunction modes)? How do you clean and validate the sensor data? Please explain, because otherwise I won't step into one of these machines.
Unacceptable - please don't bring those sort of views to HN.
> I can be asked to produce my driving licence in limited circumstances (suspected of driving offences and stopped) at a police station within 7 days

You must stop when asked to by a police officer. They don't have to suspect an offence. https://www.legislation.gov.uk/ukpga/1988/52/section/163

You must produce, when asked, your documents. They don't have to suspect an offence. Not producing when asked is committing an offence, but there's a defence if you produce your papers within 7 days at your nearest police station. https://www.legislation.gov.uk/ukpga/1988/52/section/164

> No ID needed for NHS care,

There's no ID needed for primary care or emergency care. You may be asked to prove ID if you get secondary care. The NHS number is irrelevant for whether you get charged or not.

It is an offence to refuse to give your details or to give false details to a PCSO (so not even a police officer) if they think you have littered or they think you have behaved anti-socially. Or they think you're part of a group that includes some people who've behaved anti-socially and they've asked the group to disperse.
This reminds me of the cheap water purification thing that got rolled out across poorer bits of Africa. Any cost reduction possibilities for this design?
That's seriously overdiplomatic. The plane was rushed and it was constructed very badly. It was absolutely irresponsible to bring it into service, it's not a question anymore. It's a plane that crashes itself automatically into the ground and that killed over 300 people.
I can understand it looks weird but it isn't. A faster processor has no more real time guarantees than a slower processor from the 80s

Of course, the faster one can do more stuff in less time, but for flying an airplane (or going to the moon) the amount of computing power needed is much less than people imagine.

The issue here is adding more computing into an aging platform. But there's nothing inherently wrong into using an older platform into the flight computer.

Now I'm not sure if for certification purposes they would be allowed to replace it with modern hardware but just keeping the functionality the same, I believe the answer would be yes, that they are allowed (but they probably didn't want to rewrite the sw and recertify the hw)
Doesn't it vindicate the we need to weaponize space?
> You're going to have to invest the time to do it right up front

This is the problem with most places I have worked: "I want this and I need it today." Scripting is the obvious answer.

Then it will change to "I want it to run every day" and even if I say "it needs more work" the response will be "well, it's working now, so why do you need to fix it?" And so a shell script or several go into production and I can't stop it.

In any case, even if you use something more formal, you can still write fragile, error-prone code. Bash or Perl is not the problem - you can do great work with those tools, if you have time.

Awaits / yields produce state machines. See [0] for an example of how that works behind the scene (or just decompile your stuff with ILSpy/dotPeek), but basically the code between yields / awaits is split into separate blocks in a new object, all variables used across multiple blocks are stored in that object along side of some state indicating where to continue on next call.

Lets pretend we only use immutable data/vars for now. We could just reset the state machines position to some earlier state and re-run it. Only with our await-like sample operator returning a different value this time. Add another operator and this would make it very easy to implement backtracking while re-using a lot of existing behind the scene infrastructure. But personally I'm not sure the result is that much easier readable than a few nested for loops. It might be, for some complicated code spread across a larger code base. But adding a new language operator is a quite high price to pay...

There are some incredible (in the literal sense of the word) geographic features in this part of the country.

I took my motorbike through this region a few years ago (riding Turkey / Iraq / Iran).

Copy paste mountains.
Scarlet salt lakes.
Stranded boats.
Burnt plains.
Ardent forests and mountains.

I watched the announcement and it seemed like more talk than action. A few new inquiries to report in a year or so and a new unit in the ACCC for big tech companies to capture. Not much new legislation, though.
The whitewash is already starting.

The 737 Max name is now being replaced with the 737-8200 term (1). I assume they are hoping that 737-8200 is not tarnished like 737 Max is.

there are several services that you can use. You can accept fiat from them and get crypto for you etc. BitPay and others provide these things. Not sure what the requirements are though. In regards of "normal", 3B will start using Libra at some point so.. that's another discussion :)
That is absolutely incredible
It made 1mA of current, 0.5mW of power. Pretty long bow to draw linking this to renewable energy storage. A kettle uses a kW or 2 just to boil water. You would need a million of them to make a packet of noodles.
Good luck with this. Community building is a tough road ahead.

unless you’re a lawyer and have a client-attorney privilege. same thing might apply here.
For administrative purposes it makes sense to uniquely identify people, but for privacy purposes it is a feature to not be uniquely identifiable. I don't think one can get around that tradeoff. In South Africa, if you have someone's ID and also their tax number then it is very easy to commit fraud.

The history of computer science is dauting. Unlike physics, though, it's the history of incremental innovations that culminated in what we have today. Thus, if you go back in time long enough, things eventually are manageable.

A good primer on the history of CS is probably Code, The Hidden Language of Computer Hardware and Software, by Charles Pretzold. I've put together some notes on it here: http://alvaroduran.com/code.

Any feedback is much appreciated!
Also in Italy: my mom has several middle names and she has one set on her national ID, another on her driver's license and the codice fiscale was calculated with only the first given name.

She's having so much trouble opening a new bank account that she's probably going to legally change her name (rather than her codice fiscale).

I agree with you that in general this system works pretty well, but we also have our nagging issues.

In general the problem is that most automated systems ask you for all the info necessary to compute your codice fiscale and then double check what you've entered, if you're one of those cases where one letter had to be changed or something like that, most online forms will complain and give no possibility of recourse.
But you’ve just described a bunch of work to do to achieve what’s GraphQL gives you for free, surely?
Probably because you didn't know about these specific US law or maybe you heard it buy didn't think it applies to you. Finally the network effect makes sure that people think of GH as a global utility.
I heard there was a similar confusion with Jesus Christ, basically another prophet of the same name around the same time. One got killed on the cross but the other one lived, leading to the 'came back from death' rebirth story.
Hasura is the best example I know of a beautiful, well engineered, well documented product that solves the completely wrong problem.

It just converts a custom syntax represented in GraphQL into arbitrary SQL queries, which is absolutely absurd. They have mechanisms to restrict access, but the fundamental foundation of the idea is flawed.

GraphQL is great in that you define the exact queries that you know to be performant. Once you resolve your top-level payload, most of the nested fields will be non-parameterized relations. These are usually just tons of multi-gets.

So in practice, you have top-level queries that you know to be performant, followed by multi-gets that you know to be performant. If you do have a parameterized field, make sure it's fast.

Amazon’s View on Unions
Abstract art isn't arbitrary in its judgement. This has been researched, and even people who say "My five year old could have done that" can tell the difference between the work of actual five year olds and very abstract smeary work by professional abstract artists.

The rest is about form and content. There are certainly aesthetic form rules in most of the arts, but the real point of art is the content - emotional distillation of lived experience, psychological reflection, even social commentary and satire. Even terrible kitsch has some element of this, and the best art is very densely packed with it,

A proof cannot be art because it has none of that subjective content. You can maybe - at a reach - apply the results of a proof in a social and political setting, or discover it has some relevance to psychology.

But the proof itself is content-free.
Let's do this again next month for Alexa!
Yeah this is fairly trivial to replicate. Plus if you’re using Clojure there aren’t many side effects anyway so the effect of rolling back is largely the same.
There’s nothing free. Requesting “any view for any potential client” will most likely cripple your backend because you can’t optimise ad-hoc queries.
All the EU countries except for Denmark, Ireland and UK have identity cards.

All the EU countries except for Ireland and UK are part of the Schengen Area (or are obliged to join in the future, for some recent members). It remains to be seen what Ireland status is once UK is out, depending on what kind of border is put in place between them.

The trend in the EU is for more control (regarding IDs and in many other issues) and this was not well appreciated by many UK citizens.
Exactly. Imagine those 2 downed jets were full of Americans or Europeans. The governments would have hit Boeing so hard people would remember that for a century.
