Lots of IT shops nowadays are struggling to contain a BIG MESS while still providing new features that the business needs. So the skills that are most useful at director level and above, are how to cope with the BIG MESS and how to extricate the business from the BIG MESS. Most likely this involves lots of compromises and the usual techniques of managing in the midst of chaos by evolving bit by bit to get closer to some overall architectural vision.

As far as the technology goes, there are many ways to have an IT infrastructure without a BIG MESS. So technology does not help you here. What matters most is deciding on an architectural vision and leading the whole company towards that "better place". If you believe in silver bullets, then you will fail.

If you read Peopleware and it made sense to you, then you are probably on the right track. There is a huge literature on management techniques to guide you. Pick a path that you can walk and just do it.

The most annoying trend in SaaS
This is interesting stuff, but I wonder has anyone verified the results in practice? These methods are all quite simple. They assume, for example, that the quality of an item is independent of the quality of the surrounding content. This is clearly not true. When Steve Jobs died, for example, no other new in the tech community was going to get air time. There is also the need for a variety of content. I think we all know how boring it is to read endless "I wrote X in Y" posts on HN, where X is some simple software system like a blog and Y is the language du jour (Node.js / Go / whatever).

In the machine learning community the above problems are addressed with submodular loss functions, bandit algorithms, and no doubt other methods I don't know about. Now I don't value complexity for its own sake, so I wonder if the additional power these approaches bring is warranted.

> If the teacher has not covered the commutative property, then it might be unwise to let a student continue with this line of thought.

Built in to this is the idea that only the teacher provides knowledge to the student. Consider that the student may have learned it from a parent or someone else, or from a book.

Thus, the author regards this not as a test of the student's math skills, but as a test of being able to repeat a specific teacher's math pedagogy.

I like (and agree with) some the comments:

> I have to disagree with this. Your intepretation of the Wikipedia article is fallacious: Wikipedia says “The multiplication of two whole numbers is equivalent to adding as many copies of one of them, as the value of the other one.” They did not define “one” as being the first number in the problem a x b, nor “other one” as being the second.

Beta is conjugate prior of binomial distribution. That means is you start with
prior beta, and likelihood has binomial distribution, then posterior obtained
using Bayes theorem also will have beta distribution (with different
paramters).

If you look up definition of beta distribution and then write down formula for
posterior it should be quite clear that result is also beta distribution -
modulo normalizing constant which may be a little more tricky to determine.

Since most FP codebases do the same with a few orders of magnitude less code, no, I'm not aware. Though I imagine that if they had to copy their code for every single instance of their generic typeclasses, they would quickly amass many millions of lines.

The kind of divisive item you describe is rare, at least on Amazon. What happens most commonly is that everyone loves something or everyone hates it, with some noise (e.g. 10% 1 or 2 star reviews). In this case, it makes sense to promote the item that has a 4.5 mean score and 100 reviews over one that has a 4.7 mean score and only 5 reviews. You want to account for the uncertainty when there are few ratings. If you don't, all the items at the top of your search results will be 5-star 1-review products.

What stops an exchange from quantizing to, say, a second or so? Use proportional matching, or something even more clever like POSIT does. I'm sure there's a reason that this simple idea doesn't work but I haven't figured it out yet.

As far as more decimals, it doesn't sound plausible that all the market makers are gonna come up with the same price to 8 decimals. So the time priority will give way a bit to price priority.

From the article you linked to...

"Still, if we don’t care about sustainable use of geothermal, we can just keep drilling new holes to deplete one region after the other. In this sense, we could evaluate the thermal endowment in the upper 5 km of crust under land. The average temperature in this layer is about 60°C above the surface value, so that each cubic meter (3300 kg) contains 180 MJ of thermal energy. Summed over 1.4×1014 m², we get about 1026 J. This is 250,000 years of our global appetite. A quarter-million years might seem close enough to indefinite that we’re willing to call it sustainable. Truly it is a substantial endowment. It’s the practical considerations that hold us off from rushing into this resource."

There are some practical issues to overcome before geothermal could take a bigger share of the energy mix, but they're being worked on. Whilst I don't believe we should ever rely on one energy source, not even when we have nuclear fusion, I still think that geothermal has enough potential benefits to make it unwise to rule out whilst we still need to move away from polluting sources of energy.

Here's one idea for improving the practicalities of geothermal:

"Bhargava’s other hobby is tackling the world’s dependence on polluting fossil fuels with geothermal energy. His twist? Use a grapheme cord, which is stronger than steel and an impressive conductor of heat, in lieu of the usual steam-and-chemicals to gather and distribute underground heat. By his estimate, geothermal energy like this could replace 85 percent of fossil fuels."

>Why not businesses, schools and workplaces change their open and work hours?

It's far easier to legislate DST than to to regulate every business, school and workplace. In Indiana, DST and Time Zones are already political sore spots. There would be absolute revolt if they attempted to tell everyone to change the time they operate and everyone certainly wouldn't do it of their own volition.
> To make web pipes work, just to even get started, you first have to solve authentication and data format/transfer standards.

Unix pipes have already solved the authentication problem. For instance, to stream a compressed harddisk copy safely between two hosts you can use the following statement:

dd if=/dev/harddisk | gzip -9 | ssh user@xyz dd of=hdcopy.gz

Data format standards could be implemented right now using encrypted JSON or something like that. I would prefer Lisp s-expr by the way because they could be handled immediately in client/server lisp without any transformation.

> third party hosted

That is the exact thing that needs to be avoided. By using such a service, you are allowing that service to aggregate browsing logs.

It doesn't matter if any particular site logs it's OWN requests; it is expected that if I ask you for a page, you (as the 2nd party) may choose to remember that transaction. Without aggregation, any service only knows about the people that choose to interact with that service. This mirrors fairly closely traditional expectations where e.g. a shopkeeper knows that you walked into their shop, but most people would find it more than a little creepy if that same shopkeeper allowed a 3rd party to kept detailed notes about their customers.

The problems start when you decide to let other people eavesdrop on what should be a two-party transaction, especially when they have access to a lot of these interactions. By aggregating logs, the knowledge about someone changes from known that they used a particular service, to knowing their pattern-of-life[1] (and more).

> what should a site administrator use

I'm truly sorry that there are not a lot of options (that I know of) for better server-log analysis. This area has suffered a lot of damage from the Service As A Software Substitute[2] monopolies.

I suggest pressuring vendors for better analytics software. There may be a market for better local-only, no-services-involved server-log analysis tools. Until such tools exist (or are found), you're in a hard place, because lack of tools is not justification for betraying the activities of your users to a snooping 3rd party.

lol the arrogance of a lot of people here is astonishing. The programmers I do know in the aerospace industry like dicking around with all kinds of stuff. I'm pretty sure any of the ones I'm thinking of could pick up node.js in a heartbeat if they had a reason to. :)

Usually, those things are seen as tools you use to solve problems. And the fun is in solving problems. Seriously the people getting all wrapped up in the node.js are just as bad as the stereotypical veterans that spent 30 years wrangling fortran on a PDP that haven't learned anything else.

> except you get also the screen resolution and a few more infos.

It is quite the sense of entitlement to think you have a right to that information. You have a right to log what people ask you (the server logs); logging anything more just makes you a creepy peeping-tom.

> I don't mind

That's nice. That doesn't mean everybody else agrees.

You're right, in general - it is the aggregation at Google (et al) that is the real problem. My point is that it is highly presumptuous to assume everybody is ok with a particular type of logging.
Anyone know the history of this protocol, was it much used at any point?

the problem is that its not available to buy.

sadly this is an issue with many Microsoft products, for example one of Windows 10 selling points is Cortana and yet its only available for 3-4 countries without any indication on when the rest of the world will be able to use it.
The Amiga ecosystem perfected this: most (good) software featured an ARexx 'port' - an API, based on the REXX language, that enabled any one program to communicate with another. Or one could simply write an ARexx script to automate a process.

Here's an example of the first occasion I seriously used this, when producing a 3D anaglyphic animation for video: graphics frames - two images for left and right - were rendered in VistaPro (the original 3D landscape generator); as soon as rendering was complete, ImageFX (image processing software) picked up the output and combined the channels to make an anaglyph; this was then sent to the PAR animation recorder (a video recorder). So, THREE separate large packages from different software companies, working in synchrony with each other via ARexx. The whole operation worked so smoothly and efficiently, first time, that I still recall it with awe.

Sadly, yet another killer Amiga feature that never made it to modern computing...
I don't invest in startups; I work for them, and plowing the proceeds of that work back into startups (or any other tech company) seems like bad diversification to me. So no, I don't have an ulterior motive.
I disagree with the author. He confuses Math with Computer Science. In Math, a x b and b x a are both equal and equivalent. The division example with switching places is ridiculous. Learning from mistakes is part of the process. Even kids who suck at Math won't switch places when dividing or subtracting!

A road trip into the Free Software Foundation's early days
Since the question was "Ctrl-z works universally", I feel obliged to point out that ctrl-z sends SIGTSTP, which can be blocked--not to be confused with SIGSTOP, which cannot be blocked. I don't know of any program that does intercept SIGTSTP (except a test program I wrote that tries to print the name of any signal it receives), and I suspect that "polite" interception would be to release a few resources and then accept being paused--but, in theory, a program could ignore it.
The libraries concept used to extend the OS were another cool Amiga feature.

I would say the closest we have today to ARexx experience are Powershell and AppleScript.

Anonymous will reveal names of about 1,000 KKK members
I came up with a three-tier model myself:

1. API or API-like things (grep)
2. Highly configurable app (Photoshop, Word)
3. Default-heavy app (Instagram)

The tricky thing is that 1 and 3 are the easy slices, relatively speaking. If you only need the 80% case, it can probably be automated into something as simple as a selfie app, with a finite, well-understood level of design and engineering. And if you need something extremely custom, you want the data model exploded into its smallest parts so that you can put it back together again - and the small parts can again be relatively simple, well documented, and easy to maintain.

But the middle part, the product that is complex and configurable, but not really "programmed" with code except through a limited script layer, is the fat middle, because it demands so much more UI, and an experience that is well-integrated, amenable to default workflows, and yet also very easy to customize. Over time, big software projects always drift towards the middle.

The article specifically fits my model's type 1. A type 1 product is nearly ideal for the hacker who wants to glue together a bunch of different technologies. It only falls down when the abstractions are too crude or mismatched to the problem. But the operating system itself is more like a type 2 product - there are numerous assumptions about what the environment, services, access methods, etc. look like, conventions that were established early on in computing and haven't yet been revised. Every programming language makes accommodations for working in that environment, and not your weird custom operating system.

We will have way, way, way too many people noodling around with this to scrutinize everyone's work. The linkage between the CTF and our recruiting work will be largely automated, and entirely opt-in: nobody that works for us is going to notice you until some automated thingy asks if you're on the market, and you tell the automated thingy "yeah, I'm interested in being recruited".

The overwhelming majority of people noodling with our CTFs, including most of the "best" players, will not be job candidates.
