It's a very light article with a title that over-promises.

The fact that Pessac was easily modified appears to be accidental, and the article finishes with a passing comment by LC that I wholeheartedly agree with, but doesn't really amount to much.

Feels like something dashed off to somehow prove a point?

I very much like Tim Harford's reporting when it comes to statistics and numbers in life and the news (his More Or Less radio programme/podcast is great) and his older stuff on economics, but his more recent obsession with "cautionary tales" (the title of his other podcast) frequently seems to involve stories that are superficially interesting but frequently fail to convince me that they have a strong point.
5 years ago we evaluated cold storage for 100 TB of data. Even at that relatively small amount magnetic tapes were much more cheaper even after accounting for an extra copy to ship to a remote location.
There must be more to it than that, considering all the generational change otherwise.
Projects of that size takes time. Multiple decades before any actual work is not out of the ordinary. The planing is aiming at finishing the tunnel in the 30s, so I would guess that it'll be done in the 40s.
Could you elaborate a little more on this? What kind of headaches do you have in mind? (No pun intended :D)
Show HN: Free forex signals provider backed by A.I
Hi all , I m a developer but a bad forex trader,
I built Forex Neuron,it s a free forex signals provider backed by A.I for short-term trading.

This app monitors pairs rates in real-times, when the algorithm spots a signal a notification is broadcasted on Telegram, Twitter, facebook and Discord, signals are executed in real time and if it reaches the profit or loss price it will also send a notification.

the web app is free, no account required “ I m not interested in your data, I have a life and I respect yours “, to get real-time notification on signals you have just to follow the Twitter, Facebook, Discord, but I recommend Telegram it's the best and the fast way to get notifications.

Signals are not 100% accurate, spotting the right pattern in a noisy data is very hard especially for short terms, but I'm working on it mostly every day to improve the algorithm, it's the main reason why it's free and friendly advice never buy a forex signal service it's usually a scam , if someone can predict forex with 100% accuracy he will not need to sell his signals.

I have worked on this project since 2016, I have created many versions, some better than others and this is the last version.I'm trying to keep this web app trustable as much as possible, no data manipulation, no loss hiding and everything is executed in real time.

I plan to add many other features to this web app; a social network for traders, EA for Metatrader, prediction for crypto …etc depending on my free time :)

Your feedback will be appreciated so please feel free to comment and ask your questions , thank you all for your time .

> it's great to get into the train without doing all the procedures you do with a plane.

Well, if they just let go of the security theater and phobias, we could theoretically have a situation where you just board with no procedures, like on a train: Ride a local train/metro/bus up to the larger train station, flash your card or pass or what-not, maybe flash your passport, put your suitcase on the baggage cart or beltway going up to the cargo hold, and get on the plane. No queues, no checks and no nothing - basically like a train.

I realize it's not that trivial to switch to that way of thinking of air travel, but again - not impossible.

All these architecture and workflow methods (Agile, scrum, TDD, DDD, Kanban, even 12-factor) have a few useful and logical concepts at their base. Then people create a dogmatic religion around them, often without even understanding the why.

An experienced and reasonably intelligent person usually has no difficulty in figuring out which concepts are most relevant for a given project to increase its changes of success. In reality, that person just ends up fighting adherents of the chosen corporate or hive-mind dogmatic religion or finds themselves surrounded by people in pure ignorance of matters beyond throwing code over the proverbial wall.

You should not "follow" agile or DDD. You should understand its concepts and apply them when suitable, as part of a broad toolkit – as with anything in life.
I was in a similar situation many years ago (different ticket software though). What we did was spinning up a spare server with the backup data and script an extraction/injection tool to populate the production multitenant sass.
That was the first thing I looked for as well. I have a service monitor (combination tracking generator and spectrum analyzer) witch CGA output. There's a fair amount of old engineering equipment with CGA out. They typically have green CRT built in, but if you do hook up an external monitor you get a rather nice color display.

Not a total loss, CGA was also also popular in cabinet arcade games. You can get converter boards. All the ones I've seen had 5-pin headers and you have to build your own cable.
Can you count on what you measure?
Psychological tips aren’t enough: policies need to address structural inequities
For many companies releasing their code is not something they would usually consider, regardless of whether it offers a competitive advantage or not. It's just not in the culture. They don't see what they have to gain by releasing the code, but they worry that it may create issues if they do.

So basically if you want to convince these companies to open source some of their components "what do you have to lose?" is not good enough, you have to give them an actual incentive. I suspect that outside of places like HN very few people really care about Broadcom's binary blob in the rpi.
I found that too. It’s relevant today I think, as office-based companies start to think about hybrid futures.

Many of the (relatively) newfangled HTML input types exhibit this kind of half-baked behavior, coupled with a surprisingly stubborn lack of extensibility.

type="number" doesn't support thousands separators in any meaningful way.

type="date" and type="time" only display their values in the user's system locale, not the locale of the page. There's no way to change the format.

type="color" doesn't support RGBA and can't be in an empty state. If you try to unset its value, it always defaults to #000000, even in dark mode.

type="email" and similar text-like types don't offer any feedback for invalid values until you try to submit the form.

No wonder people are just using type="text" and relying on Javascript to achieve reasonable behavior.
"In the past" ? My current employer, a high growth company uses HAProxy and Nginx in production with no plan to change anytime soon.

Those are not tools from the past. They still work really well and there is no law requiring your brand new startup to be on AWS.

Airlines also typically charge for luggage, RyanAir charge extra for anything they can think of, including choosing a seat, and people booking at shorter notice subsidise those who book in advance. The cost difference for most passengers is probably smaller.
May I ask who paid for your comment? Why do you automatically assume that there's an organized campaign when the viewpoint disagrees with your own?

[Removed. Thank you commented below for the reminder to keep my background out of it]

I have watched the democracy, WMD, and human rights theatrics deployed before. There are always people saying "let's be a little skeptical" and they are always called treasonous and unpatriotic. Yet we find and time again that there is wisdom in heeding their warnings.

Yes I see what you mean and there certainly are other sectors that are paid even more than developers and are probably even less “important” to society as a whole. It’s helpful—for my mental sanity at least—to being reminded of that so I appreciate your reply.
this isn't going to be any better than just loading from the two buffers into registers then storing the other way around, like:

a = load(ap)
b = load(bp)
store(ap, b)
store(bp, a)
ap += step; bp += step;

any instructions to "do the swap" are a waste because generally load-store are separate instructions in SIMD instruction sets (and even if that wasn't the case, that's how they would get executed anyway)

if you want to avoid polluting the cache there are SSE instructions for loading without caching, which might be worthwhile

edit: this might be useful in a SIMD context where you need to swap two registers, where the cost of using another register is higher than the cost of the 3 arithmetic instructions. i could totally imagine that happening, but it's nothing to do with caches or memory

1) Internet System Handbook by Marshall Rose and Daniel Lynch - Overview of The Internet from the 1990s. Very valuable to get the big picture.

2) An Engineering Approach to Computer Networking: ATM Networks, the Internet, and the Telephone Network by S. Keshav - Excellent textbook which covers three different types of Networks.

3) The TCP/IP Guide by Charles Kozierok. - Reference: http://www.tcpipguide.com/ Start at "Networking Fundamentals" : http://www.tcpipguide.com/free/t_NetworkingFundamentals.htm

4) Mathematical Foundations of Computer Networking by S. Keshav - https://news.ycombinator.com/item?id=30964707
They have, and there will be more. The US should continue to listen and consider how they can change. Avoiding the topic is not a viable way forward.

Yup, you're an adult, you make up your own mind.

If you're in my office and I recommend a medication that you decide not to accept I'm not going to twist your arm to take it.

I might take calculated risks and do things myself, but when there are unknown risks due to utter lack of knowledge, you're right I wouldn't advise it for others. In my role trustworthiness is everything, it simply is wrong to do things that violate patients' trust. So true I won't take unnecessary chances with their health and well-being.

Not my job to defend conduct of others of decades ago. I could argue with your comment about "overprescribing", but really I see no point debating non-issues. Discussion only means something when based on facts, IOW it always comes down to specifics, not squishy generalities.
There are very real cases where you may want to swap around actual memory though. Gabage collectors do quite a lot of this type of large memory exhanges.

The flexibility and scalability of the cloud comes at a cost. Scientific, static and non web but IO heavy workloads are almost always better off run on-prem or in a co-located data centre with servers paid up front. As is most things in businesses, it’s a trade-off one needs to think about and make. The smart ones will come out ahead, and those that blindly follow FAANG and drink their kool-aid may or may not come ahead, albeit with a heavy hit to their(or their VC’s) pocket.

If you’re a startup that simply have a bunch of web apps and APIs where uptime and network are your major costs, on-prem is only going to become a worthless headache.

A good Systems Engineer should help to figure out such choices. Anybody need one?
Well the linux ptoject does just fine without strict aliasing based optimisations. Pretty much everything on windows is built with msvc, which doesn't depend on strict aliasing for optimisation either.
You can tell yabai to leave your windows alone with

yabai -m config layout float

And enable FFM with

yabai -m config focus_follows_mouse autofocus

And voila, you have FFM without tiling!

The WebRTC Bitcode Soap Opera (Saúl Ibarra Corretgé)
I've worked on a project with similar setup: Gradle packages for API, domain and infra and it was one of the nicest developer experiences I've had for backend. Better than classic monolith, in which people sometimes put stuff wherever without respecting the boundaries or microservices, which were pain to develop when multi-service communication was involved.

The cherry on top was when one of my junior collegues told me that he was struggling, since the project did not let him use dependency, that did not make sense.
When "Do As I Say and Not As I Do" is the primary principle of US foreign policy, then Whataboutism is the utterly correct response.
Sure, there are advantages but advantages are not one sided. It's not like choosing between Netflix plans where you pay 9.99$ for 2 screen and HD streaming and you can upgrade to 14.99$ package with 4 screens and UHD streaming. It's more like choosing between Netflix and Amazon Prime. You might get fewer options to watch but you also get one day delivery and some really nice content too. Often, you end up having both.

Also, trains can switch lines, disconnect, run on the same line back to back etc.

Just look at the Europe railways map: https://commons.wikimedia.org/wiki/File:High_Speed_Railroad_...

I suspect, with some standardisation and automation, you can end up having very good point-to-point travel options by train. Even better than airlines maybe. The current inefficiencies could be due to poor management and weak integrations. Can you imagine how great could be to have Europe and Asia wide rail network where automated carriages and rail switching systems coordinate to achieve travel from any train station to any train station?

My reading of their comments is that they are trying to say that social media and news media can be characterised as having recommendation systems too, not just song and movie platforms (I don't know who exactly they're arguing against – I've never heard anyone say that recommendation systems can only be for songs and movies).

I don't think they're really paying much attention to the dimension you're splitting it along, i.e. whether the recommendations are personalised for each user. The huge important idea they have in their head is that recommendations can apply to user-generated social media content too.
In the Winter War, there were about 70,000 total casualties for Finland and about 350,000 casualties for the Soviets, or roughly 1:5.

However, Finland lost 9% of its territory and had to relocate 12% of its population as a result of that war.

Losses is not everything that counts.

> Duncan and Davies actually cobbled together two generations of
electronic bottles. Their first generation of devices, the ones that
sailed along the Ganges, had plenty of cell towers to ping along the
way, so a SIM card would do. But the researchers also wanted to see
how plastic bottles might behave once they get to the ocean. So they
outfitted a second generation with GPS. Here they took inspiration
from their prior work tracking sea turtles: GPS works great on the
open ocean, far away from any cell service. (Their designs are open
source, so any plastic researcher can build their own, and even
improve upon the system.)

So cellular networks in the earlier system doubled as a localization + communication system. GPS is useful only for localization - I assumed they use satellite for actually communicating with and tracking the bottle?
> You'd turn down quality bug-reports and code-contributions in the name of blocking spam?

Absolutely I’d “risk” it. Even a negligible amount like $10, would reduce the noise significantly. I’d also pay that in a heartbeat as a user.

> I don't buy the idea that its principles need to be thrown out in the name of anti-spam practicalities.

What “principles” are you referring to?
It's a tricky one, lots of people (obviously not saying yourself) equate effectiveness of a fighter/interceptor with manoeuvrability alone but that is only a tiny part of what makes a modern fighter effective and a relatively negligible one at that.

Missiles, Radar, Datalinks and Avionics are what matters on the F16 with stealth added on the F22/F35.

If the F16 can see the Mig29 first (either via it's on-board radar or a datalink to a loitering AWACS) and has weapons that can reach further then the Mig29 is at a catastrophic disadvantage before the fight is even joined properly.

The reports I've seen where F-16's have gone against Mig-29's all seem to reach the same conclusion, Mig-29 is more manoeuvrable below 200kn where F-16 is more at +200kn.

Thing is actual gun range dogfights are rare outside of exercises and if you are doing 200kn in one then you are at a severe disadvantage against an opponent who isn't since preservation of energy is the key criteria in a gun fight.

All that said though if an F-16 finds itself in that kind of a fight with a Mig-29 outside of an exercise then something has gone very wrong.

There’s more than a kWh rate for that though. There’s battery backup power, diesel backup, and failover hot switching. It’s not like just plugging in your phone to charge.
An adjacent topic, since TFA is about acoustic guitars and this is about electric, but I recently came across an excellent video where a guitarist tries to determine exactly which parts of an electric guitar affect its tone.

He did it by methodically swapping parts around on a cheap kit guitar and comparing the sound to a quality model, and he winds up finding the body shape/material appear to have no effect at all. He even gets closely matching sounds out of a "guitar" with no body at all, by keeping certain other elements (strings, pickups, electronics) the same as the real model. Really surprising results!

What Ancient DNA Reveals About Life in Africa 20k Years Ago
Mostly British people's poor education in languages. It's not that other European languages would be hard for us to learn, it's that most people in the UK de facto don't learn another language to a useful level (presumably because English is so widely spoken that we can get away without doing so). Which makes it very difficult for most of us to engage with European culture, media, etc even though it's often quite similar to our own and I suspect would otherwise interest us.
It is not clear what your requirement is: actual understanding of thermodynamics (nobody does, just learn the equations); or the History of thermodynamics.
