Looks cool... but I'm worried about repeatability and accuracy. I've seen a lot of similarly-designed 2-motor "drawing robots", and the precision definitely wasn't 0.4mm (as claimed). I imagine this could be difficult given the use of gravity to supply the lateral cutting force?

I used Heroku to get my project off the ground, but costs are adding up now. What holds me back from migrating off Heroku is I don't have time to learn devops properly, kubernetes, maintain servers etc.

This looks like a nice middle ground for me. I should be able to migrate to flynn on Digital Ocean pretty easily (easy deployment of flynn infrastructure, same buildpack system). I'm sure there'll be regular maintenance involved, but it looks like nowhere near as much as a roll your own kubernetes cluster.

> So you say your non-PHP requests which would do the same thing would finish in hundreds of microseconds? I have very hard time believing it.

Yes, they do. Phoenix/Elixir is a nice way to get below the millisecond, and even with Java you can for most requests go below a few milliseconds.

And you can obviously handle far more requests at once, as you have all the code already loaded in RAM, and just need to jump into it, instead of reparsing it, or copying it back from a cache.

So, you used PHP 12 years ago and comment based on that.

You have a point though. I used this internet thing about 17 years ago, it was terrible. Only dial-up. SLOW! And don't talk to me about browsers. Netscape? Internet Explorer? Ugh. Forget it. I don't care what they might have changed, or replaced or completely removed, its always terrible.

The language/runtime have problems, just like every other language/runtime that exists, but complaining about a version from 12 years ago and comparing functions that aren't even part of the language anymore seems a little odd to me.
Both this and other PaaSes remove a lot of the plumbing. Also, the target audience is different. PaaSes offer self-servixe for end users: for instance starting a new database on demand through the user interface. You can achieve much of this with Docker Compose, but your users can't.

The Docker-PaaS movement reminds me of content-management systems in the early 2000s. Everyone (myself included) thought it'd be great to spend loads of engineering effort reinventing the wheel, instead of delivering business value.

"How often is your hardware fucked up enough that you need to move to another machine?"

VMware HA runs quite a bit IME for a variety of reasons (network failure, storage issues, etc). "The network is reliable" is a classic fallacy of distributed computing.

More often used is Vmotion and DRS which transparently moves VMs around physical hosts at runtime with no downtime and very minimal performance hit . Servers, switches, and fabrics need maintenance, firmware upgrades, hypervisor OS patches, etc. in most data centers.

"That would be great, right? You paid some $ to VMWare and now your servers never go down?

VMware FT is used in almost every major company on the planet that runs virtualized database instances that can't go down. It is serious technology.

The problem with your argument is that most php sites fail when I/We use them(throwing exceptions on the site - really?!), they've the worst security on average and php is also a slow and hardly maintainable development platform. Yeah, you can create crap fast but that's all. With this "fast iteration" bs you'll live in an illusion that you make money for the company but actually it's the opposite and you're contributing to the deterioration of IT - if there would be only php, the internet would be far worse and we'd have the same technology level as in the 90s.

That is my point entirely to OP. If the concern is the Gov. is willing to block new technology adoption bc of concerns of mass unemployment, then it isn't unreasonable to think the Gov. would allow the technology and hide some of the unemployment by "redefining" unemployment.

I am not sure why I would be down voted as these moving goal posts are a well known and controversial issue, including, but not limited to the many variables you highlighted.
In fairness, PHP was in a different place 12 years ago. The language has improved in that time. There are still lots of warts but the language and ecosystem have worked together to push it forward.

From looking at your KY tool, it sounds like the pain point you're having is that there's a lot of boilerplate repetition around loading configmaps and secrets into your containers, is that correct?

If that's not far off the mark, have you looked at using an object-oriented k8s client? I've been playing with a pattern where I create classes which know how to render themselves into k8s API objects, and that gives the ability to use language-level looping to create, for example, lists of env variable definitions in the resultant spec.

I'm writing python apps so PyKube[1] is the base client that I've used, but there are clients in lots of languages at this point.

I also tried out Helm, which looks like it has a way of generating k8s yaml files using Go templates, and given a set of config parameters[2]. Unfortunately my use case was a bit too dynamic to fit in that mould, but this seems like it could be useful for many things.

Again downvotes. It'd be nice if people actually replied instead of downvoting.
Networking and storage have been traditionally the biggest differences with cloud vs. on prem. Bandwidth and latency has been quite variable on AWS. Disk I/O and IOPS sucked for many years.

That said in recent years it's much less of a problem , though the fixes tend to require a lot more expenditure for provisioned IOPS, dedicated hardware instances and 10 gigE network instances. But then nearly any legacy shit app can run in AWS ...unless it needs some crazy specific configs like live hardware assisted disk replication, or VMware FT levels of resilience.

> safety and versatility

That's exactly what expressiveness is. If a type system is versatile enough, you can express what you need to express without bypassing type safety.

> anything except the specified type

Even in this sense, subtyping doesn't weaken a type system. The definition of subtyping is the subsumption rule: given `S <: T` and `x : S`, you can derive `x : T`. (TAPL, p. 182) For similar reasons, adding ML-style let polymorphism to a type system doesn't weaken it.

> strong and weak is orthogonal to safety and expressiveness

Then what exactly is it?

The harder I'm thinking, the less sense my inner monologue seems to make. Even for fairly simple things -- other than reading -- it tends to be a jumble of half-articulated sentence fragments and images. When I'm thinking hard, there tend to be significant portions that I have no idea what to call them.

So the inner monologue clearly isn't how I think (what I use to think), but seems to be something more like samples from a debug trace or audit log.

Agree with everything you said... but I find it not applicable to this particular candidate given his answers.

It's possible that he got frustrated, became condescending towards the recruiter, and the recruiter decided to screen him out.

There are plenty of companies who turn down candidates that are false negatives for various reasons. Author should probably not take that personally and just apply again.

I once asked what it would cost to update my Prius' built-in navigator maps: cirka 200 €. And after few years it would be again out of date. I'm not sure whether to blame the car manufacturer or navigator software supplier for the situation, but at least this is very short-sighted thinking from Toyota.

By the way, I still prefer the built-in unit because it has better integration with audio system and windscreen HUD. The usability is actually pretty good despite its age.

Similar issue: the built-in navigator can show realtime location-aware traffic warnings from TMC broadcast, but only if they are non-encrypted. In my country they switched to commercial / encrypted TMC broadcasts few years ago, rendering the feature unusable for my car, and Toyota won't update the navigator unit to support encrypted TMC.
Completely OT but was this posted because of the "Remediation Plan for WoSign and StartCom" thread from yesterday?
Completely agree with you. Seems more like a personality mismatch, than a lack of technical skills.

Seems like both parties were at fault here:

- The interviewee for being a little brusque about his answers, and despite understanding the _intention_ of the question, giving potentially off-putting, difficult answers to check over a quick phone call.

- Google recruiter for seeming to ask questions she/he was a little out of her/his league to ask. If you don't understand the nuances in and around the questions you're asking, you are not qualified to evaluate someone's responses.

Wouldn't worry about any one particular interview, there are too many great opportunities in tech right now to let any one bad interview let you down!
> http://cookbook.hacklang.org/recipes/get-and-post/

The fact that their "recipe" relies on one file being run in "non-strict" mode for it to work at all is very telling about how short-sighted this "vision" to remove superglobals is.

Even if you went the whole hog, and removed $_GET, $_POST etc. You force users to use filter_input() to get variables. (Why doesn't the Hack "recipe" do this anyway?)

Now tell me how you access a a structured POST body. e.g.

foo[bar]=baz&foo[baz]=bar

Oh. Right, you can't. Because filter_input only returns scalars.

If you remove $_GET and $_POST people will just do the equivalent in the new construct:

$query = "SELECT * FROM username_list WHERE username='" . filter_input(INPUT_POST, 'username') . "'";

$query = "SELECT * FROM username_list WHERE username='" . $myFancyPostObject->getString('username') . "'";

The PHP developers who understand why using raw untrusted input is dangerous are already using the facilities provided to make the input safe for use, in some cases built around access to $_GET and $_POST.

The PHP developers who are already using raw untrusted input in dangerous ways will simply find new dangerous ways to use the data.

Discovering aliexpress was pretty awesome

I'm sure that you got lucky. My first experience with them was terrible. I ordered a phone (it was a dual-SIM android device) which wouldn't work for either voice calls or text messages. Tried SIM cards from different carriers, but nothing would work. You could connect it to the WiFi, though. Reporting the matter to AliExpress was terrible, those guys would insist that they're concerned, would look into it, but nothing happened.

though admittedly haven't used/tested a lot of it

I'd recommend doing it.

This view is pretty common for people reading their first language written by someone using their second or third language. This comes people that just isn't as good at writing and expressing themselves. This does by no means make their thoughts less valuable. Sometimes you just have to open your mind to other people even though the words come out in the wrong order.

English is not my first language either but I don't write "I'm sorry for my mistakes, english is not my first language" because that should be pretty obvious. And if it's not obvious, there is no need to say it, right?

The standard Google phone interview.

I got almost the exact same questions. My interviewer seemed more capable though.

I also wasn't as technically correct as this gentleman so my slightly less correct answers were more "right".

As sad turn of events given that I would have loved to answer the same way as he did here, these are much better answers than mine. But this is just technically recruiting, it's a crapshoot at best. It's much better to just take jobs at places that don't insist on trivia competitions.

No way this will beat a dedicated astronomy CCD camera. And price point is already not so attractive, ST-8300C costs $1995 and while has 30% less sensor area, is light years away in thermal current at given temperature, and quantum efficiency. For me, if a wanted a color camera (bad idea most of the time), picking between ST-8300C and this would be a no brainer in favor of ST-8300C.
A one-size-fits-all cannot work. Ever.

For an SQL-based DB (i.e. where the data mixes with the logic in the query) you should be using parameterised queries anyway.

For general data sanitisation/validation you should look at the filter_* functions.
That makes me sad. I worked of a lot of those pages there.

> ctype_digit is broken. Try passing integer values.

Well, ctype_digit takes strings, not integers. So don't be surprised if you pass the wrong type to a function and it doesn't work as you expected.

Some of your criticism is valid, but you can't go around talking about how PHP isn't rigorous enough, and then complain tha some functions don't work as you'd like when you give them a wrong argument type.

Your other arguments are more about bad developers as you say it yourself, anyone who actually cares about what he does knows you have to check equality with ===, while the array argument problem is less well known, but actually almost unrelated to PHP: POST or GET is user data that can be any type and should be checked. Only the last of your examples is actually a problem to me.
I suggest you go and have a long hard look at Crystal. From your comments I am getting the feeling you could appreciate it.

Dear Network Operators, Where Are Your MANRS?
Everyone knows that in the long run the industrial revolution was a positive. But at the time, the disruption caused lots of misery. Farmers were driven from farms that had relatively good living conditions, to cities with awful working conditions, living conditions, and lower wages. Eventually things improved, but it didn't happen overnight.

What does it matter if there are more clothes, if there aren't any consumers to buy them? We are looking at a world where humans are obsolete just like horses. There is nothing an unskilled worker can do that a machine can't, at least in the near future. And many skilled workers do jobs vulnerable to automation as well. The vast majority of the human population is unnecessary, just as horses were after the invention of cars.
