All the fasteners I have seen are standard metric sizes, what speciality tools are you referring to? The side cover screws can be stubborn but even a Philips #3 with an impact driver ($20.00 at the pawn shop) pops them right off. Conversion kits to standard allen head screws are cheap, on the order of $50.00 for the whole engine.

There is a special nut on the oil spinner but that's the only specialty tool I can think of on the bike until you start actually disassembling the whole thing and you don't even have to remove it to do an oil service. I guess the shock/steering head adjuster is a specialty tool? But that was included with the bike so not hard to find either.

Parts can be a bit harder but since these things were so popular it's a lot easier than any other bike from 1969. Also the aftermarket is huge if you don't care about staying totally stock.

The main idea is to create a learning platform for 9-13yo kids, with high quality apps to learn English, basic coding, and (!!) life skills like personal finance, critical thinking, even using Google efficiently. Then you can just download and deploy it on RaspberryPi/OrangePi or old PCs in your country and distribute it to disadvantaged kids.
A good book on this theme is Matt Ridley's "The Evolution of Everything", which argues that social institutions are generally a lot more evolved and a lot less designed than people realise, and that we forget this at our peril.
Wow that's... actually a really good idea
It's not that we can't change things, is that doing so sometimes costs $10s of thousands of dollars. We often have instruments running on XP, that work completely fine, but the software will not run on 7, 8, or 10. When we contact the company to ask about an update they say "sure, but you'll need a software maintenance contract, with a re-certification fee, etc. etc, for $40k." No faculty member wants to pay $40k to move something working to a new OS when we can put it on our unrouted internal network and keep it running on XP for $0.
Size is less of a factor there, too.

Linux, Netlink, and Go – Part 1: netlink
I can't speak for moxious, but I agreed with their post because in my understanding of business and engineering and from being around people of either backgrounds, engineering seems to firstly prize hard, analytical skills and only later on considers creative solutions, while business gets around to analyzing things after considering the things within a/the bigger picture.

In terms of seeing the forest vs. the trees: My thought is that engineering might be so concerned with seeing and analyzing the trees that they do not get around to considering the forest as a whole and recognizing where no tree presently (but could eventually) resides within that forest. (I think that "recognizing where no tree presently resides" is what a dreamer type might do.)

A big issue that I see with framing business people in this light is that few of them do seem to think entrepreneurially, but that may explain why you haven't run into more dreamer types.
i'm wondering if the tighter control of information (i.e. the firewall) makes this alternate modality uniquely resilient to some types of failure.

it may not have the same upside potential but perhaps it can lumber along under its own momentum. maybe even create enough illusion of momentum to weather dips that might otherwise be more detrimental.

to the extent it might need to evolve to be more democratic it could do so in a way to give the illusion of choice but the freedom to choose between false options isn't much of a choice.

clearly i'm feeling a bit cynical after this election cycle. yikes.

anyway i thought your comment was interesting and it got me thinking.

AFAIK AWS runs patched Xen. They seem to have built quite a bit on top though, and e.g. Have re-written lots of the network stack. This also seems to be why their networking stuff would break or be very flaky regularly as of a few years ago.
I agree, the concierge services felt like a weirdly distinct service.

Also, the business model seems weird. Why would someone pay $100/month for, hopefully, years in order to cut down on one-time costs and hassles around the initial renting? Regardless of whether it ends up being cost-beneficial, it just seemed like a weird match to me. You're "subscribing" to a service that does a bunch for you in month 1 and then nothing in later months.

Maybe that's what the concierge part of the service is meant to address, but I'm very dubious of that portion of the business.
I think their recent cock up is a great example of why they need an ops team regardless of whether or not they're in the cloud.

> as long as they first outsource the football coach and the President's personal administrative staff.

This is bitter and pointless. At many (most?) US universities with football programs, the program is with cost neutral or profitable.

Saying that the president should outsource his staff isn't compelling. You should be making an argument for why outsourcing IT is bad if that's what you think, not just saying "well then outsource this other thing!" as if that's an argument. Or will you actually be happy if the president outsources his/her staff?
"But no, in both the worlds of programming and operating systems, there already were better thought-out solutions."

There were differently thought-out solutions, but not necessarily better or worse. Perhaps the issues they thought out didn't matter as much at the time and very unlikely to matter even a little bit today, and who knows how much they got wrong and much worse. It's very hard to speculate. But one thing I'm sure of is that these things cannot be really well designed from scratch and all the problems manifest only once they are used by people. So widely used systems can only be compared to widely used systems, not something niche or unused.
Not really that inflated. I built a Clevo laptop about 4 years ago, and compared it to an identical System76 build, it was only $70 difference.

That thing was pretty poor quality though. Died fall of 15, replaced it with an XPS 13 which is still going strong.
Having worked in this space, people do what celebrities do, and I was just as surprised. They are "influenced", I put it in quotes but it is by the strictest definition of the word.

This is a really nice writeup! Very clear and easy to understand.

I did notice one conceptual error near the beginning:

> Computers can pull this trick off too: they take a value, and store it at a location in memory. Then, given a key, they somehow use that key to figure out the address of that memory location, go to that location, and return that value.

> Figuring out the address is called hashing, and maps that work like this under the hood are called hash tables.

That definition isn't right. Looking up a key to get a value isn't called "hashing". Hashing and hash tables are just one out of a number of ways that a program could do this.

For example, given the data objects in the first illustration that have Key and Value properties, you could simply use a linear array of these objects. Then you loop through the array looking for the matching Key, and there you have your Value. Hashing is not involved here.

Of course, as the array gets longer, this simple loop gets slower and slower. That's where you start looking for faster algorithms and data structures such as hash tables. But the hash table isn't fundamental to doing a name/value lookup, it's just one way to do it.

Another example is a trie, very different from a hash table but could be used for the same purpose. Tries are often used where you may want to get a list of values that match a prefix (like an autocomplete) but they can also be used for a full match just like a hash table or a linear array.
> Failure at every level has to be simulated pretty often to understand how to handle it

Keep in mind, S3 "fails" all the time. We regularly make millions of S3 requests at my work. Usually we get 1:240K failure rate (mostly GETs), returning 500 errors. However, if you're really hammering an S3 node in the hash ring (e.g. Spark job), we see failures in the 1/10K range, including SocketExceptions, where the routed IP is dead.

You need to always expect such services to die in your code, setting the proper timeouts, backoffs, retries, queues, and dead letter queues.

What Company to Hire When the Door or Glass of the Door Breaks?
A digital watch would benefit from those batteries. Smaller watch.
I think it has some kind of firmware that manages the backlight, so if you switch between really bright and dark windows a lot (like a browser and terminal) then it changes brightness a lot which is annoying, and there's no way to turn it off. Personally the only thing I've had issues with (on Linux) is the soundcard producing low-level noise because of the CPU going into powersaving mode. It's fixable but I can't remember exactly what I had to do to get it to stop.

On the bright side, it does help a lot for the battery life (I get around 8 hours usually).

I also have an older system76 laptop and I would definitely recommend the XPS (13 or 15) over it if you want something lightweight with good battery life.
>Why should he re-architect his system and introduce some Amazon-specific dependencies like S3 just so he can give Amazon money?

You could make the same argument going the other way though - why should GitLab spend money recruiting/hiring people, leasing space, setting up monitoring, etc, if their solution today works? Why should anyone re-architect their system to give $COMPANY money? When your bare metal's RAID controller craps out and you have to order another, will his customers be understanding of his decision to move to bare metal?

It doesn't makes sense to factor in fixed costs of such a migration.
I agree with your basic point, but i think it's not about theory vs. the real world so much as confusing the worst case for the practical case.

I often think that approximation algorithms, randomization algorithms, fixed-parameter tractability and "special case" deterministic algorithms are what people should look at if they are interested in positive solutions (as opposed to lower bounds). Not to mention the incredible success of SAT solvers.
social opium
It's hard to believe this came from a place of humor after reading the otherwise dry article.
But the males without the gene are indistinguishable from those with it. They reproduce at exactly the same rate - there is no selection pressure for normal males.

You can try it in computer simulations if you like. It would be trivial to set up. Each generation the percent of normal males decreases. Eventually they are all gone.
I'm guessing the emergency spillway was originally implemented in BASIC.

* sometimes the diff is irrelevant (I started from scratch, or primarily added code instead of modifying or removing it)

* other times, it's enough to know only that a line has changed. I've configured Vim (with vim-git-gutter) to show symbols next to added and removed lines

If you tried to start the Amish now it'd never last, it's too large a leap. But the Amish society evolved slowly over time much like others. If you went back to the early days then the Amish wouldn't be that different to others around them. It's just that there was a bit of a split and our societies have evolved in parallel since then under the influence of different values.

Crashing the System: 1990 AT&T long-distance cascade failure (1992)
Oh frack I hate drivers: the inertia of their vehicles range from a NATO bullet (30km/h with partial shock) to a 75 canon and they want to blame technology for they lack of concern to the others' well being.

When you handle the same potential destructive power as a BF gun, you have the same duty as an operator of a gun:

- not being distracted (be it by a phone, a blowjob or a conversation);

- taking it as a matter of life or death;

- being responsible for your actions.

- follow security rules.

There is no excuse. If ISIS is now using vehicles instead of guns, it is simply a logic of potential damage. Our society is basically considering owning guns is bad, but cars/truck that can be more destructive are less regulated to not bother economical interests thus it is good.

Stap it, anything that can endanger others' life should be regulated. Else, let me pilot without a license the next plane you are gonna take to travel.

Some of this relates to the size of the phone in a case which add a lot of bulk and seem overly popular. But, another factor is larger phones need to be very thin to be comfortable in many pockets.
Low. Mine is 25 miles, which I consider high. But 6 miles... I'd be trying to bike, or maybe even jog that.
Sadly this doesn't work. There is close to zero selection pressure for genes that improve evolution. Because of sexual reproduction, evolution operates on the level of genes. And genes are randomly mixed up every generation. A gene that increases the probability of beneficial mutations doesn't help itself spread. See my other comment on this thread for more specific examples.

The word "absolutist" has several possible interpretations; moral absolutism is only one, and in context I don't think it makes sense. The definition I was using, which seems far closer to how Taleb appears to be using the word, is (from dictionary.com--merriam-webster.com gives a similar definition):

"the principle or the exercise of complete and unrestricted power in government."

In other words, an absolutist about power, not about morals.
They may not be mutually exclusive, eg. you could have a system of a world-wide government whose only job is enforcing trade & property rights and providing physical security, while delegating responsibility for social mores & resident services to the city state.

She is a wonderful teacher. When the very first MOOCs were introduced, I took AI taught by Sebastian Thrun, Peter Norvig and Databases taught by Jennifer Widom. I could contrast the teaching style of these experts. Jennifer Widom is approachable, methodical, breaks down complex topics into easily manageable chunks and pushes you hard with attainable goals. The other two geniuses (Norvig and Thrun) will present something that you will have struggle (with frustrations because denial isn't an option with them) to get it. I loved her way of teaching and I am glad she taking on responsible roles.

There are two points to my argument:

1) the administration cannot properly value IT because they (likely) do not understand how it works

2) the administration likely values their own staff and their athletics much more than the revenue they generate, and thus would never outsource those staff even if it was costing the school a lot

Regarding (1), I would point out that it's unlikely they realize how inefficient having remote IT can be, but they'd realize how inefficient it would be to have remote coaching. For instance, the reason that you wouldn't outsource a football coach is that they need to have direct, personal communication with their team. Having someone in a foreign country "coach" your team would be very unproductive. Likewise, a President in another country would never be able to keep up with the many meetings with professors, deans, and bureaucrats that keep the school running.

So, my point is more that a President would easily recognize the problems in outsourcing certain jobs, but not realize that many of the same problems will occur when you outsource IT. The truth is that infrastructure is often extremely complicated, with many interdependent features. But when you aren't in the same location, you cannot as easily manage it.

> My point being, drawing from the practices of people multiple centuries ago might not be the best thing

Given how much of cognitive behavioral therapy borrows from stoicism in this case I think this assessment is premature. Stoicism like buddhism are great philosophies on how to deal with the world as it is. And to understand that most of the problems we think of are products of our own mind.

Stoicism doesn't do either denial or say its natural. It forces you to reevaluate how you think of the question. For that alone it is worth drawing from.
