> immense history dating back to the late 1800s

It's such an american thing to say that something just over a hundred years old has immense history. I own furniture and other stuff, which my grandparents inherited, that is probably older than that.

Sure the stuff has some history, but it's barely a few generations.

I’m looking for a very lightweight laptop to use as a portable Firefox/Tmux console. Minimum requirements are USB-C power, 1080p screen or better, and small form factor (<13”).

I’m OK with hacking used Chromebooks (this is a replacement for a C720), but was wondering what else might be out there...

Hello greetings... What's happening in the Crypto world
30 years ago the discrimination was firmly against young people, today it has flipped on its head. Yet we have larger HR departments, rules, etc etc. So some serious questions need to be asked.

But having felt the brunt of age discrimination when I was young and now older, I kinda angst. Kinda feel like generation discriminated sometimes having caught it at both ends.

Because after programming either professionally or as a hobby for over 30 years, no “tech” is “cool”. It’s simply a means to have enough money deposited into my bank account to enjoy an upper middle class lifestyle.

In given week, I’m up and down the stack from the web to the infrastructure (AWS). I found all of the things that AWS enabled that took literally months to provision in the old world “cool” for about a year and then it became just another means to an end.
When the touchpad on my daughter's a Yoga stopped working, I had a technician exchange it within a day at our home. I got the same 2-year service level for my Lenovo X390 for 50$ extra and it's worldwide. I think a Mac you have to bring to the Apple Store and leave it there.
Only tangentially related, but having spent the past 6 months (and no doubt the foreseeable future) working with a senior engineer with a thick accent and only a so-so grasp of English, if you can't express yourself clearly or understand native speakers without them having to make allowances, then I don't think you should get credit for being smart. At that point, it doesn't matter -- the whole relationship is based on communication, and in a field like software engineering where discussing and exploring ideas is so paramount, it's at best a nuisance and at worst detrimental to productivity and working relationships. This isn't me stereotyping, either -- there are plenty of other people in the teams I work in with thick accents but a better grasp that I find it much easier to work with and learn from, even though they might not have as wide a breadth of knowledge.

I'm not saying it's easy to learn English to that level obviously, but that doesn't mean it's not a problem.

Argue all you want, but it’s still passive voice. The sentence does not tell the reader who or what is the source of entitlement. Even if it did, it may still be passive voice (You are entitled … by AR XX-X …). The same sentence in active voice is “Army Regulation XX-X entitles you to jump pay for …”

Your suggested improvement is in the active voice, but it’s still wordy. Using can weakens a statement, so look to eliminate this worthless verb. Prefer will or in this case get to the point with “Claim jump pay on Form DDXXXX for the time …”
Same as with trains: Its not cabins pricing thats expensive, its flights being too cheap - mostly due to tax subsidising of kerosin and similar. With proper energy costs and carbon pricing the bill would look different

How can you find that odd when there are so many mongodb instances on the open internet?
> Nah, you've probably just got a fragile configuration that won't scale and will cost you money in downtime, lost sales, or failure to live up to contract.

Those are the tales consultants and engineers that like to play with toys tell: it is a typical case for a premature optimization. The odds of you having enough traffic that needs to scale are slim to none.

If you do need to scale, the odds are your apps are over-engineered on corner cases and under-engineered in the main path: if your ORM takes 300 ms to initialize on every request without fetching any data from the database "scaling" is the last thing you should be worried about.

It made sense in the past. But, it's not actually focused on productivity, it focuses specifically on suffering and the effort. When productivity is possible without strenuous effort, something which wasn't very common in the past (it was possible in things like art, which was consequently never valued as highly as dogged physical labor), it is viewed with suspicion and derision. Society is structured around placing high value on sacrifice and suffering as a consequence of the Protestant Work Ethic in the west. Productivity is beside the point. I believe this is one of the main reasons why the introduction of computers has resulted in skyrocketing productivity paired with frozen wages, and it will get worse. As everything was built around the idea of rewarding physical exhaustion, discomfort, strenuous effort, etc, when the majority of work is mental work which has no real outward signs of strain, it won't be rewarded. As a result, longer and longer hours will be expected, wages will not rise, and any cries for understanding by workers will be met with derision by the public at large. "It's not like you're working hard."

Working hard is valued, and should be pursued for its own value. Asking for compensation is crass and devalues your effort. Being productive without suffering or straining is not valued. It is seen as "cheating" and whatever is produced is seen as inherently less valuable. These are problematic perspectives that are causing us social problems and will continue to do so until there is a social re-evaluation of things. Until then... burnout for everybody!
Work doesn't have to mean your fulltime job. Work can mean a side project that you're passionate about, or a side business.

When is being more efficient at anything a bad idea? If you can get your day job done in 2 hours vs 8, maybe you can argue for a raise or the ability to work from home.

I agree, notation can be useful for concision. Far less for clarity.
Instead of a black or white thinking, I'm wishing that mathematicians use more well defined English in their proof, but still use notation where it is clear and more concise.
So were the misissuances evenly spread among CAs or were there some that were clearly worse than others?

Microsoft President: Democracy Is At Stake. Regulate Big Tech
This is the problem with news and I don’t know the solution. It’s hard to trust a company that is spending lots of effort explaining how valuable and worthwhile they are.

Many of these arguments boils down to “pay me or lose me.” While it’s true that good journalism costs money that doesn’t mean we should pay for mediocre and bad journalism. And it’s pretty hard for me to tell good from bad.

This reminds me of site that when you fire visit them put up a window that asks you to subscribe. I don’t know if I want to subscribe so how would I be able to choose. But if a site relies on people subscribing without good judgment then that’s probably a sign that they don’t have a good feedback loop for value.

Even the nytimes asks me to subscribe just to read for free. I’m not willing to do that to read the infrequent article from them and they are one of the world’s best. I used to subscribe but it was a chore to read regularly because of all the fluff.

Unless there is a micropayment tip jar, I’ll continue to read only the journalism that is able to survive from non-targeted ads. Which, I think, works out ok for me as I don’t regret very frequently choosing the “lose me” option.

I was applying to a job with a large game studio. The interview was going pretty well, I'd thought. We talked a bit about how we'd implement certain gameplay elements, the content of the projects we've worked on, and overall it just seemed good and we all seemed to get along pretty well.

Then they asked me how old I was. Their response to my age was, "Oh... maybe it's a little late then. You're not too old, but... kind of cutting it close by just a bit."

I was 26.
I found the food on the Amtrak Coastal Starlight (Seattle-LA) better than expected, and their wines were much better than I expected (comparable to Asian airlines' wines in business class). A pleasant journey all round really.
What profession is this article about? Surely age discrimination varies hugely depending on profession.
Dead reckoning and sensor fusion are the real answer. Over 20 year old Etak patent:

"Based on the previous position of the object, the GPS derived position, the velocity, the DOP(dilution of precision) and the continuity of satellites for which data is received, the system determines whether the GPS data is reliable."
I think the biggest threat of plastics pollution is loss of our ability to use plastics as a long-term building/manufacturing material. Very few microbes can metabolize plastics now, but not zero, and the ability will only spread as plastics (and especially high surface-area to volume ratio microplastics) become more common in the wild. Microbes evolve fast, and they have access to horizontal gene transfer. Heavily fluorinated plastics might survive but I expect all cheap plastics will end up easily biodegradable.

It's potentially a major inconvenience, but if we pretend it's as big a threat as CO2 pollution then civilization will have collapsed before it happens, so that's one way to avoid the problem.
That is the only way to sell recreation or relaxation to Americans. Benefiting yourself or pursuing pleasure always has to be justified. I can't recall the source, but I read a long and insightful article about this specifically and the difference in viewpoint between Americans and most Europeans. It explains why some products and trends perform differently across those places despite so much else being shared.
Allow me to provide a contrarian view. I'm not disagreeing that age-discrimination does not exist, however I must say it's not always the case.

I'm 35, so I wouldn't qualify as young but neither old.

Businesses tend to recruit younger devs for few reasons:

- They can be easily convinced to work longer hours

- They are typically paid much less

However there is one trait in older devs that make them undesirable:

- They tend to carry baggage from the past. This comes in various flavors, such as biases one has regarding the path of their careers, their interpersonal relationships (social and official), technology choices etc.

The thing about biases are that the mind that nurtures them can easily justify them, thus making the very biases appear rational and logical.

Furthermore not all biases are negative.

They are a useful piece of memory that comes with experience. The question is: Can you consciously choose when to apply the bias -or- Is your mind driven compulsively to apply them indiscriminately?

I would argue that victimhood about agism does not help anybody. If you are in a craft, where the barrier to entry is low, be prepared to compete with the fresh crop of talent coming in.

There's a lot more I could write about this. But I leave it for another time.
> Yes, but it puts American consumers at an advantage! Are there more consumers or businesses?

Interesting perspective. I can see a parallel with healthcare insurance:

- one big non-profit subsidized provider -> cheap baseline service for the masses, third party providers cover for the niches of the market, third party providers forced to innovate

- lack of subsidies/regulation -> expensive baseline service for the masses, essentially the subsidy that gave you cheap service now becomes profit for the third party providers, no need to innovate when you can comfortably get rich by inflating the baseline service prices

> At 66, I am in excellent health.... Then presume I’m Miranda Priestly... I do not want a childproof cap on anything that threatens to ruin my expensive manicure ... I do NOT have any children or grandchildren!

If you're 66 and you're still sitting around in a corporate job, and you have no children because you model yourself after a BS character from a BS movie then you're really just taking up space for someone who needs to feed their kids and family, has a potential to grow, and a better place to funnel the earned money than your "expensive manicure"

Giving a job to a younger person, unless you're irreplaceable and a "master" of your craft is not called age-discrimination, it's called "doing what's right for the society" even if it sucks.
Many supermarkets in the UK outsource maintenance of their car parks to private firms, who benefit from being able to charge after a certain period has elapsed. It's the same with hospitals, train stations, council car parks. It makes me sad.
One thing I don't like, which was present in this article, is throwing up our hands and saying "but there's nothing we can do". Of course there is. Nobody says that about racial discrimination. The simple truth is that age discrimination is not generally viewed as a problem. The attitude is that older workers aren't as productive, so let's let companies do what they want. In some states, the same argument used to be made about non-white workers, and the people that lived there had the same attitude.
But you can't "pay to reduce your carbon impact". That money, as a rule, does not reduce the amount of carbon you emit. It just makes you feel better. What would make a difference is not flying in the first place, not having a fancy car, not upgrading that phone every year, living in a smaller house, not having kids, not eating meat, not eating non-local fruit and produce, etc, etc. Not quite going back to the stone age, but reducing the quality of life considerably. And that's something the upper middle class is just not prepared to sacrifice, "climate catastrophe" or not, gotta have that beachfront property (looking at you Barack and Al).
IMO, chroot is good for changing root :) but not for security.
Example: zfs clone your current root, chroot there, experiment / test /etc.

We can all help stop this. Everyone can reduce their contribution. I cut out nearly all packaged food, which reduced my garbage to where I empty it less than once a year (I'm in month 13 of my current load). I was pleasantly surprised that doing so cost less, reduced food preparation time, increased diversity of food, and led to more social interaction with friends and farmers. For the record, it took a couple years of practice to go from weekly garbage to monthly to yearly.

That's just one example. Everyone can reduce some. The more you start, instead of just accepting and throwing your hands up, the easier each next step.

The producers will see the trend and stop buying plastic.

Of course there are other ways to act: legislation, creating healthier alternatives.

The point is: everyone can act starting here and now and they will find joy in it. It may take time, but acting on one's values is rewarding.
Pen and paper don't need to be fought with to extend our brain's visual and mapping abilities. There are almost no friction to put thoughts down. It's much slower than imagining things but it doesn't rely on short term memory so we can build and think about more complex abstract thinking.

I've heard more than once that its related to living conditions being so much more clean / sterile than they used to be. If you don't come across different substances regularly, your body has a hard time determining whether they are good or bad and is more likely to react when it finds them.

The counter-argument is that Piketty's models and data are at least as credible as the standard models and data used in policy econ.

For example Magness & Murphy prefer the UK's Office of National Statistics to Piketty's figures - because it's supposed to generate gold-standard objective economic data.

In reality the ONS produces the UK's unemployment figures by considering anyone who works one hour a week as employed. Similarly anyone who labels themselves self-employed for tax purposes is considered "employed" even if they do no work at all.

It says this clearly on the ONS site.

It's quite strange to accuse Piketty of cherry-picking and distortion when these egregious - even comically obvious - distortions pass for official economic "fact" at the national level.
I don’t think business model is the right term. But open source consistently produces excellent software. I think better than any commercial software.

I don’t think the solution is all software being open, but if by business model we mean a way to consistently produce good stuff then it would be a great option for news.

I think the ultimate solution is to figure out a model for news that doesn’t rely on echo chamber subscriptions, privacy eating ads, or govt sponsored bias.

It’s a tough nut to crack, but I think an OSS-like volunteer with reputation model is the most likely. I’m way more likely to donate to a Linux Foundation/FSF/Apache Foundation style org that figures out how to get good truth and relevancy than NYT.
> you're really just taking up space for someone who needs to feed their kids, has a potential to grow, and a better place to funnel the earned money than "expensive manicure"

That's a ridiculous assertion, if someone is physically well and wants to work it's nobody's business how they spent then spend the money they earn.

Choosing to have kids or not shouldn't give you any special status in the workforce at all (though in reality it often does).
I agree and they have already proved they couldn’t. They use to say that their investment in content will keep attracting users even when its not new - ie their library content has value.

But they admitted that they didn’t sign up as many new customers last quarter because they didn’t have big new releases to attract customers.

They are still taking on billions of debt for both licensing deals and to create new content while their major upcoming competitor - Disney+ - has multiple income streams from their content and most of the cost of content has been repaid multiple times by the time it reaches Disney+.

Streaming is also a feature and not a standalone product for Amazon, Disney, AT&T and even Apple. None of these companies live or die based on their streaming product, it’s just a check mark.
> If you're 66 and you're still sitting around in a corporate job, and you have no children, 9/10 you're really just taking up space for someone who needs to feed their kids, has a potential to grow, and a better place to funnel the earned money than "expensive manicure"

That seems very judgmental to me.

I don't plan to have kids due to genetic conditions and other reasons, but by your reckoning, I don't deserve a job once I age because there are other people "more deserving."
In the United States, literally nobody should be asking your age during a job interview.

Check out the SC2 arcade and co-op missions. They perfectly target the 'mid-core' strategy gamer and Blizzard has pushed a lot of content into them over the past years. I would not be surprised if it dominates the normal ladder in hours played, just like the old Brood War UMS maps.

Probably a strong reason why there isn't much competition - why build a new game, when you can weave less competitive mechanics on top of an existing engine and game universe that already has fans?
Just to make sure I understand what's happening here:

1) a direct chroot("../../../") would not work, as the kernel restricts ../ to / if at the chroot-root.

2) chroots are not nested.

3) By making a handle to a path, then chrooting, the security measure 1) is disabled for that handle (as it's outside of the current chroot), and the kernel doesn't keep track that it was created in an earlier chroot.

Is that right?
