What are the toxic chemicals used in chip fab? (serious question) I have literally all the chemicals mentioned in the first chart on this page in my modest maker garage, sans arsenic and phosphine; though anyone with certain rat poisons would have them.

There doesn't seem anything more toxic than what you would find in your run-of-the-mill chemical research lab. One time I got to handle a few liters of trimethylsilylcyanide (at work, not in my garage lol), that was an exciting day in the lab.

This is but one example of articles I've read talking about how "toxic" chip fab is...and I'm like, have you seen the coal industry?

https://www.allaboutcircuits.com/news/reevaluating-the-toxic...

> Aside from being caustic, many commonly-used chemicals are known human carcinogens. Some examples that can carry high risk are toluene, acetone, methylene chloride (DCM), xylene, chloroform, and isopropyl alcohol.

You mean paint stripper? Granted, DCM is being phased out, but I've worked with gallons of the stuff. Xylene/toluene are in spray paint. Acetone and isopropanol are literally under my bathroom sink. Acetone is straight-up not a carcinogen, and IPA is carcinogenic in the same way bacon and beer are carcinogenic. Like, technically yes, but it's not exactly methyl iodide.

> Others—like glycol ethers—may even cause reproductive harm.

You mean windex? Contains ethyl/butyl glycol ether (cellosolve).

Sure later in the article they mention mercury, cadmium, tellurium, those are pretty yucky. But how many NiCd batteries do consumers improperly dispose of every day?

Chip fab is probably no worse than your average autobody garage/paint shop combined with a metal plating facility. Yeah don't go dumping your effluents in landfills or storm drains, but we already have protocols and pipelines for chemical hygiene and waste management.

Chip fab actually has the advantage of tons of money to throw at proper chemical hygiene, unlike fossil fuel industry with razor thin margins.

Can we do something about the mining, fracking, and coal burning industries though?
> This is impressive.

Fun fact: employers don't think so. Not in my case anyway.

Tactics/Strategies (not comprehensive):

* Synergize as much as possible. If you see overlapping knowledge, use that to your advantage. If you need to do a 3rd year course and the prerequisite at the same time, use that to your advantage.

* Plan like a maniac. You need to have access to exact course schedules and create your own schedule.

* Use your time efficiently. Does a lecturer suck in lecturing? Skip it. Does a practical class / lab class waste your time? Skip it.

* Use your time smart. Conflicting schedules? Make sure (or pay even to be sure) that someone records the lectures for you.

* Negotiate, negotiate, negotiate. 2 exams at the same time? You have to convince either teacher A, teacher B, course coordinator A, course coordinator B or the dean. You need to only convince them once.

These type of things.

It seems like there’s been a rush to the science mindset and the art part has been ignored by many in industry for the last 5-10 years.

I remember wanting to be a PM, but experience with the MBA-ification of the field has embittered me.

Seeing products (like Xamarin.Forms) systematically destroyed by focus on shallow metrics has been really sad. I remember being excited for that product to get a PM. Then the product just kept getting worse and kept stagnating. Developer interest has dropped precipitously and they haven’t managed to stay competitive with React Native or Flutter, despite having Microsoft’s resources.

All the time I give feedback on Visual Studio. I am a loyal customer, but I can only get “We’re closing this issue because we only prioritize problems with a broad customer impact, and you haven’t gotten enough upvotes” so many times. I’m sick of it.

I don’t think I’ve met a PM in the last 5 years that hasn’t made my impression of the company they work for far worse. And it comes down to focusing on business metrics and ignoring the two other sides: customer experience and interaction, and interactions with internal developer partners.

I don’t know why companies are only hiring and cultivating MBA-style, metrics-oriented, value-blind PMs, but the abandonment of art has made the industry worse for everyone involved.

Surely he should be familiar with logical reasoning then as well. Yet the argument present here is 'A bad, therefore B' without any evidence that B doesn't also have its own problems. If he is an authority on deontology, he would do well to provide evidence by way of his writing.
> I think you dramatically underestimate how many people suffer from RSI and how much it affects their lives.

I'm not saying it isn't high; I said it would be higher. The distinction here is vital, as I'll go on to explain...

> According to one survey, nearly 60 percent of computer office workers nationwide suffer from wrist pain while at the computer, and 51.2 percent say their keyboards are placed too high.

(source: https://consumer.healthday.com/encyclopedia/pain-management-...)

So more than 5/6 people who have keyboard related pains believe it is due to the placement of the keyboard.

Of those remaining ~15% of users, how many of them are getting pains due to other circumstances (keyboard type, other positions in 3D space, or even just their own posture)? How many of them might still have their keyboard too high and don't even realize it (those excluding them from the first category where they should have belonged)?

Hence why I said the number of complaints would be much higher if QWERTY itself was a major contributor to RSI because QWERTY is near universal whereas the other factors are not yet the other factors still vastly dominate the statistics.

As for the rest of your comment, you're literally just reiterating everything that I've already said to you in my past comments.

To summarize (because I think you're fixating on the detail and thus missing the overview for it): for all the talk about how "bad" QWERTY is, other environmental factors have a much more significant impact on the health of the typists.
Was that part of IMF structural adjustments?
I've been playing Freeciv for years, but was disappointed that the pool of players was dwindling. A few of the members of the community stepped up to work on revitalizing the project. We decided to focus on WebAssembly to run on browsers, dropping support of the GTK+ and SDL clients in favor of the Qt client that we decided would make it easier to create a Wasm port, and eventual mobile apps. There's still a lot of UX tuning to do, but we wanted to put this out there today to get some early feedback.

Author here, it's a duplicate. The whole issue has already been on the front page and discussed extensively, including this article. See the comments at https://news.ycombinator.com/item?id=30017919
Unless the problem involves people, in which case a healthy dose of the right emotions and some subjectivity can help the process along.

And behind every technical problem there is always a people problem.

You could solve that by using a public calendar where you just block parts of your time for concentrated work and let people know about it. Obviously that depends on a more explicit agreement. In offices, it's often more implicit, via "headphone plugged in" etc, but it's a good idea to find a form of expression for that in remote environments as well.

Make a product that solves a problem, and then sell that product.

Can be something very simple. Eg. something like joining PDF files, sharing photos with your family, hosting a caldav server, a shopping list app that syncs between android and iOS users...

Then get people to buy your product. Start with selling it to your coworkers or friends and relatives, and anyone else you know who fits the target audience.

Spend a lot of time talking to your users and when folks run into issues change your product to avoid them. Try to understand what they really need (not always the same as what they say they need)

Iterate on the product for a while, and you should have a profitable product.
Cognitive load is such a technical term. You don’t want to (and probably cannot) hold 30 different things in your mind at the same time. That’s pretty obvious.

Programmers have such an affinity for technical-sounding terms.
Context matters. I recommended a static site generator to a very specific person. Here's the comment I initially replied to:

> I have thought about moving my personal blog onto something that isn't someone else's service. But every time I think about running my own blog server, stories like this come along.

So... yes. I was assuming that OP was going to both be the person running their personal blog and writing on it, and I was assuming that OP is pretty technically competent if they were seriously considering running their own blog server.
If anything forms of late/post capitalism are even more concerned with time than industrial capitalism - one might say that industrial capitalism formally subsumed time measurement, while today's attention economy really subsumed it.
The reason we know so much about bell labs is the same reason you know about certain peoples eating habits - they tell you.

I don't completely agree with him, but I interpreted him as saying:

Deconstruction is often employed in intellectually dishonest (or lazy) ways to discredit concepts by creating/employing tenuous links between a concept and its socio-cultural associations and refusing to actually elaborate on why they matter. This is often done in order to attack a concept for political reasons (as opposed to strictly intellectual ones), and people who do this are committing a tactical error. Giving legitimacy to these intellectually vacuous attacks as a tactic ensures that they'll be used against currently popular ideas in the future when they fall out of vogue.

No, the alternative is to not be a binary yes or no certification, but to construct a nonbinary scale to measure how free it is.

> A good example is when you get a bicycle, you do the equation and realize that within two years you will have saved in on the cost of public transportation.

This is more a counterexample.

I bought a bike eighteen months ago, it's my only transportation, it sits outside in the rain, and so far I have spent €0 on it. It's a good bike, but by no means an expensive bike.

> But it's when you start using it you realize that suddenly you always end up sweaty arriving to work so you need to buy good ventilated outdoor clothes

I don't get sweaty walking somewhere. Why should I get sweaty biking?

If you treat biking as transportation and not a race, you won't get sweaty.

> then your first tier brakes

I'm not quite sure what you mean, but I assume you mean you need maintenance. Well, don't buy tools, go to a bike shop. They can do it quicker and better than you can, and it will cost very little - certainly a tiny fraction of what car maintenance is.

I got a bike to _simplify_ my life and it has worked.

Narrow streets can be equipped with some kind of helping beacons one day, much like they were equipped with street lamps and canalization in the previous centuries.

Anyway, this is a fairly low percentage of the total street network. Even in Prague the medieval center is smallish (and many of those streets are off-limits to regular car traffic).
This essay contains the famous "Worse is Better" section, made popular by Jamie Zawinski

https://cs.stanford.edu/people/eroberts/courses/cs181/projec...

Summarized as:

"When tradeoffs are required in a software system, priority should go to implementation simplicity at the expense of completeness or correctness."

An interesting aspect of all this is that Gabriel argues with himself in a series of papers under a false name:

I think living in the US must have some effect.

In the UK the second hand market is non-existent with the likes of the US. You can't just pick up hardware off Craiglist for next to nothing. It simply doesn't happen

Space is another thing as well. But I'm sure there's plenty of Americans whole live more urban without such space as well.

My future prospects may be promising, but owning a large garage to tinker in, whether electronics or something like woodworking seems like an untenable goal.
You make some great points. FWIW, they don't really relate to the original post I was disagreeing with, but great points nonetheless :)

A few thoughts back:

A) There are plenty of (heavy) bikes out there with a front caliper and a rear brake activated by reverse pedalling. Suspect a similar compromise would work, and a decent front caliper/brake level pair isn't heavy.

B) In theory, simplifying the drive-train doesn't just subtract the mass of the chain - there's also a freewheel mechanism, rear cassette, chain wheels (usually 2-3), front and rear derailleur, multiple cables, handlebar shifters... and of course, the cost/complexity of purchase and fitting for these items. This would be quite a considerable weight, especially when we're talking about bottom-end components.

C) Agree totally, but (for the sake of this discussion) the comparison isn't just the drive-train of a standard bike - it's a whole standard drive-train, plus a hub or bottom-bracket motor - as deployed in current e-bikes. Current Bosch BB motor assemblies seem to be ~6.3 - 7.1 lbs each. [1]

D) Agree - ideally, there's no need for a display at all - a simple e-bike could just work.

If author is here - “vozhd” does not mean “to lead”. It is a noun form of the verb, so it means “leader” or “chief”.
I feel like this article itself is overhyped. I don't really see anything ground-breaking here, and the author doesn't really elaborate on why the examples fit into the arbitrary categories given.

> This categorization is intended to help people better understand which form of hype they‘re confronted with.

> I hope this categorization is helpful for you to understand which form of hype you‘re confronted with.

But to what end? No mention of what you can actually do with this information. I guess it's useful if you want to try to sound like the smartest person in the room when explaining it to average people who only dabble in keeping up with tech trends. They probably won't question you. The fact that the draft image went viral on Twitter is case in point.

I'd even venture to say that this probably deserves a flag.
Same here in Seattle! But I also use an ebike to get everywhere within five minutes if needed and for carrying heavy groceries and dealing with steep hills.

They call this all Silicon Valley, and that this is typical Silicon Valley. And it's not. It's an outlier. She's an outlier. I think Silicon Valley has a lot of hubris, but not this. This is fraud. And the medical industry does not have this. She just was a liar. This is not common in medical industries, Silicon Valley or elsewhere. Everybody's saying, "Silicon Valley — fake it till you make it." Come on, you don't fake it till you make it. Just make it, in medicine.
Linux already went through its hype cycle like 20 years ago. I'd say the high water mark of that cycle was around the release of Cathedral and the Bazaar and the destruction of the VA Linux stock.

Now it's deeply in the plateau of productivity.
People have this strange idea that Einstein destroyed objectivity in physics and validated all their pet postmodern theories. It isn't true.

In relativity, time is a variable that is different for each observer, but it is still objective. It's not a matter of opinion for each observer. There are formulas that determine how all the variables change, and any observer can know what the other observers' variables are by watching how they move through space and using the formulas.

While some naive Newtonian concepts such as a single universal time metric stop working, there's no wiggle room for observer A and B to be inconsistent with one another based on their personal opinions. There is one objective reality and one objective way to quantify it mathematically.

Time isn't a single universal quantity in relativity, but it's still objective. Einstein didn't turn physics into cultural anthropology.
Strong disagree. 4 year olds are trying to understand. Parents know about the 'why' phase.

Our son had a lot of questions concerning COVID,as it influenced what he's allowed to visit from one week to another. We gave answers as good as we could. He understands the basics about how diseases can spread by air, and masking is not a big leap from that point. He sometimes decides to wear a mask, even if he doesn't have to, which is cute.

He did try to stab his fork in water droplets to try kill virusses, so there are limits, but a 'logical' initiative like this shows he gets the basic idea.
Emojis are pretty complicated to either draw or type. While drawing a heart is imo easier than writing the word love, typing it isn't.
I think font selection is important to make it a fair comparison.

For each language, the minimal resolution "pixel font" that still works should be used. (E.g. Chinese hanzi are going to require more resolution than the latin alphabet.) The fonts used in Minecraft might be a good start.

However, once you do that, it probably doesn't make sense to only count the "on" pixels. Because in a minimal font, "off" pixels will probably contribute as much information as "on" pixels. So you should just count the total number of pixels required to render the piece of text.
Coming from consulting, this is exactly what it is - from a pure engineering standpoint it may be lacking but if you've read any other 'case study' targeted as business people this goes really deep. Normally it's SEO fodder crammed with jargon and buzzwords
There are three authors here: Eric Williams, who wrote the book; Donna Ferguson, the author of the linked-to piece; and Kehinde Andrews, who is one of several people quoted in the story.

I point this out because you quoted Andrews, and it took a re-reading me to realize you weren't quoting the first two authors.

Ferguson describes it as "It was all this wealth created by slavery in the 17th and 18th centuries that powered the Industrial Revolution in the 19th century, Williams argued."

This is from the preface to the Williams's 1966 publication, at https://archive.org/details/capitalismslaver00will/page/n3/m... :

> The present study is an attempt to place in historical perspective the relationship between early capitalism as exemplified bv Great Britain, and the Negro slave trade, Negro slavery and the general colonial trade of the seventeenth and eighteenth centuries. Every age rewrites history, but particularly ours, which has been forced by events to re-evaluate our conceptions of history and economic and political development. The progress of the Industrial Revolution has been treated more or less adequately in many books both learned and popular, and its lessons are fairly well established in the consciousness of the educated class in general and of those people in particular who are responsible for the creation and guidance of informed opinion. On the other hand, while material has been accumulated and books have been written about the period which preceded the Industrial Revolution, the world-wide and interrelated nature of the commerce of that period, its direct effect upon the development of the Industrial Revolution, and the heritage which it has left even upon the civilization of today have not anywhere been placed in compact and yet comprehensive perspective. This study is an attempt to do so, without, however, failing to give indications of the economic origin of well-known social, political, and even intellectual currents.

> The book, however, is not an essay in ideas or interpretation. It is strictly an economic study of the role of Negro slavery and the slave trade in providing the capital which financed the Industrial Revolution in England and of mature industrial capitalism in destroying the slave system. It is therefore first a study in English economic history and second in West Indian and Negro history. It is not a study of the institution of slavery but of the contribution of slavery to the development of British capitalism.

However, pointing out that a Dr. Pangloss can argue that $BAD_THING in history was essential, at it helped shape modern life, and therefore helps justify $BAD_THING, is to ignore that perhaps we don't live in the best of all possible worlds.
