The equipment that is sold for "this lets you do amazing things" is the worst equipment for general purpose use. In this particular comment, the magnification of a telescope is the ratio of the primary (mirror or lens) focal length divided by the secondary (eyepiece). An entry level scope might include a low magnification 25mm lens and a high magnification 10mm lens, but going down to 4mm will mean that the field of view is tiny making it hard to track objects. Also, higher magnification requires more light, so it will be dim on a small scope, and usually has a more limited range of eye relief, in other words, how carefully you have to move your head to just the right spot to see through it.

Kellner, EP: I think these are kinds of eyepieces, defined by the stacking of convex and concave lenses.

My main issue with lambda so far has been its lack of Python 3 support. I do not understand why there isn't a 3.x runtime available. We have a 3.5 compatible app with parts that depend on 3.4, and we had to cut it in two and cripple it to make it work with lambda.
Very nice - has he updated?

Interesting article but the timelines seem way to conservative to me.

For example if batteries continue to improve over the next four years as they have over the past four years, according to the article then in 2020 the batteries will weight 1500 lbs, travel 1142 miles on a charge and cost about $10k. (Or a 500 mile battery for $5k) And the cost of electricity will be, at today's rates, $1 per "e-gallon"

Who wouldn't want that? Project this to 2040 and the numbers become just ridiculous but the article suggests just 35% market share by then. I don't think so. By 2025 the market will almost certainly be strongly in the favor of electrics.

I didn't downvote you, but such claims really require good sources.
The advice here seems dated, even for 2015. Here's my advice:

1. Install an astronomy app on your mobile phone. Start with free ones, and see where it leads you. I recommend Skeye. This is good for going out by yourself and looking up things you see in the sky. For a PC, Stellarium is the best I have seen.

2. Get a camera capable of taking long exposure RAW photos, and get a tripod. There is so much hidden within the range of our FOV, that a telescope or binoculars are overkill. You'll use the camera for other things, so that won't be a special-nights-only investment. A basic DSLR should be fine, though I am curious about how well generic travel-zoom cameras do. If you have such a camera already, and played around with it, let me know.

Telescopes come after this stage.

I'm also in the process of moving from jenkins to gitlab... and until now, the process is pretty smooth and easy ...
gitlab-ci is easier to grasp and to work with... the only issues i got is about things like publishing build results (lints check or test results /counts ) althoug there is basic support for artifacts. it's not easily possible (at least for now) to fetch the artifacts for a given commit or branch without doing multiple api calls.
Fuel engine are improving too and oil price doesn't seem to want to go down any time soon. I'd say we have an interesting 10 years ahead. Electric is probably going to win, but time estimates are very hard to do. Don't forget that replacing a car fleet is expensive and takes years. A modern car can easily last 15-20 years, so even if we started replacing fuel with electric today (which we are not), replacing the whole car fleet would require 15-20 years. I don't see the 35% so far fetched in 2025...
Why would you need to be compatible with "all kinds of Unicode", by which I assume you mean different encodings?

You just need to be fully compatible with one kind of Unicode (UTF-8) and use it consistently. And null-terminated UTF-8 is no more or less safe than null-terminated ASCII, because the only UTF-8 codepoint that uses 0x00 is the same one as in ASCII.
It doesn't force you, but you lose all of it's ORM features. Sequel::Dataset is basically just a query builder so ROM would probably be a better choice then yeah.

Your assumptions hold for OS X and iOS even though they are not the same OS and never claimed to be.

> Won't it just be easier, as a developer, to create a singular platform with two XAML (one for small screens, one for large screens) that share the same codebase?

In theory yes, in practice changing the UI isn't the only problem. The problem is that a phone is much more limited, both in hardware and in what it is allowed to do.

Just as a simple example, on the desktop you can have storage that's shared between apps (at least for now), hence if you want your app's settings to be synchronized with Dropbox, you only need to detect Dropbox's folder and save your stuff in it, whereas on a mobile, you need to integrate with Dropbox's API. Plus on the desktop you usually have a lot of storage space, like my 5 year old desktop has 1 TB of storage, whereas my phones only have 32 GB and 64 GB respectively and these are high-end phones. So clearly storage is a bottleneck on mobile phone, but not on desktops. Another simple example: battery life. Mobile developers have to worry about battery life, the big and forever bottleneck of mobile devices, whereas desktop developers have never been concerned about it. For example I avoided to install Skype on my Android for two years because it was sucking my battery dry in only 2-3 hours. And now mobile Skype is so aggressive in cutting down on background chat that I cannot rely on it to deliver chat messages on time. And you want to hear the worst part? Moore's law doesn't apply well to batteries, so unless major breakthroughs happen, this will only get worse ;-)

And if universal apps on the desktop are as limited as their phone counterparts, that would turn out quite ironic for Microsoft to have turned your powerful desktop into a dumb phone just to have the same experience everywhere. Of course, them and others will try and turn this around as being for the senile grandmas everywhere that are unable to use their laptops, but many of us will have known the truth about that one.
I've been in a company that let their Rails applications grow for 7 years. Believe me, the oldest code was not pretty to read and almost impossible to refactor. When we finally had a real frontend team, the only way out was to reimplement the apps with a new architecture.

At one point I realized, I should not stick into one language and one framework. Ruby is good to know, but I'm better if I can also tackle Scala, Java, Rust, OCaml, Haskell, Python and so on. Also happier, I'd say... I can now choose the best tool for the job.

The TRUE Size of Africa: Have Our Maps Been Misleading for Over 500 Years (2013)
About a decade ago I worked at a small web-hosting company where I installed the LaBrea tarpit software (http://labrea.sourceforge.net/Intro-History.html) on an otherwise unused system and had our routers route all non-allocated IPs to said system. The intent was to use that to track IPs that were attacking (since otherwise, no legitimate traffic would hit that server) and then block them at the router level.

Sadly, source level routing on routers is slow, and even if it wasn't, I wasn't sure how to automatically block said IPs at the router level.
And don't forget that there are millions of people who have a car right now, but who wouldn't have a place to charge an electric car. People living in apartments, terraced houses, especially in the UK it's very common to see rows upon rows of houses, none of them with their own driveway.

Why shooting civilians is considered a war crime, but deliberately nuking (Hiroshima Nagasaki) or mass bombing (Dresden, Tokyo, Iraq, Afghanistan etc.) them somehow makes it acceptable?

I think this is a bit too harsh. Sure, it has a few rough edges, and not everyone's idea of prime time is the same, but Lambda is perfectly suited for lots of use cases that do not depend on very low latency -- for example, file conversions, async tasks where users can wait a few seconds such as payment processing, automating incoming e-mail workflows etc.

We've been running APIs on it for six months with no issues, and are now in the process of moving the entire backend from heroku to Lambda. So far, no major issues.

Regarding Lambda being a building block, I actually like that. Werner Vogels points out [1] that one of the key lessons from 10 years of AWS is that the market wants primitives, and that the higher-level toolkits emerge from that. A ton of third-party helpful stuff is already out, such as apex, serverless and so on. We built a toolkit[2] that lets people use Lambda and API Gateway from JavaScript very similar to lightweight web frameworks (eg api.get('/hello', function (request) {...})

Documentation is there, just not in the most sensible places, and the whole pipeline is optimised for Java processing (eg Velocity VTL for API Gateway transformations allows people to do everything they need, as long they know the Java collections API executed below).

I'm biased in the matter, but I have to agree. There are a number of problems with it.

Arrays are covariant, and object is the base class of everything. I'm surprised that nobody's noticed that already (it's unsafe: arrays should instead be invariant).

It doesn't seem like there are any first class functions, and there's no tuple class either. I don't find any mention of mapping/selecting/reducing within standard collections.

For all (heh) the boasting about the type system, covariant arrays produce other problems too. If you have a function that takes an `Array[nullable Int]` and send it `Array[Int]`, the type system doesn't say anything about it. That means you could get into problems down the line. It's also possible to take a nullable Int and do `.as(Int)`

`var v = 1 / 0` causes FPE and core dump and dumps an ugly compiler stack trace.

The documentation about abort also mentions that there's no stack trace for it.

I don't think there are standalone functions with generic typing either, just classes with generic types. I suspect that their virtual types are probably unsound, but haven't tried working with them.

> workable hybrid that is better than either of its pureplay counterparts.

I don't really need my Prius to be better than an EV or a pure ICE, I just need something that works with existing infrastructure (not much EV infrastructure in Idaho where I live, and we make semi-regular trips to nothern Idaho to visit family) while getting decent fuel economy and reliability.

Actually, now that I think about it, from a reliability aspect my Prius trumps conventional ICE engines. The much simpler design of the Atkinson cycle engine, since it can sacrifice torque that the MG's can compensate for, leads to some pretty impressive durability and a relatively cheap replacement should it be necessary - it's much more likely (guaranteed, really) that I will need to replace the battery pack before I hit 300K miles but the engine and MG's will last until the car falls apart.
it's spelt out in the abstract, no?

I disagree with the astrophotography thing.

Even with a telescope your human eyes are limited to planets and the moon, that's it. Forget about seeing galaxies with the naked eye, unless you have a 1-meter diameter telescope.
All other objects are basically points of light. Artificial satellites are really fun to see, but also points of light.

But a 2006 DSLR (EOS400) that I found in the garbage, connected to a cheap newtonian telescope can capture 1000X the detail your own eyes can see. Is your telescope too small? no problem. Just increase the exposure or ISO, you cannot do that with your eyes.

I've seen comets moving in real time. Tracking satellites, resolving detail on the ISS, the moons of Jupiter and Mars, incredibly detailed nebula, and a freaking quasar, all this from my window in the middle of the city, with the highest light-pollution.

One advice I have is, try to get a scope that's no more than 15 kg. More than that, and it's a hassle to move.

And get a computerized robotic mount. They are expensive (~800 us$), but awesome. No point of getting a 15-century instrument today.

> we don't mean any of that sci-fi and AI stuff

No one does.

Even with AlphaGo the hype was insane, but was mostly caused by people confusing weak AI with strong AI with Arnold Schwarzenegger. Any material that intentionally plays on this confusion is arguably false advertising and fraudulent.

The truth is, it's still impossible for anyone to talk about strong AI, because we have hardly been able to define what it even is. We just know we have it, and it's still unlike anything anyone is working on that has made it to the public. The people who write the papers absolutely know this. It's a common goal, but we have yet to engineer anything that remotely resembles strong AI.

For the most part, we're either still busy figuring out small but hard problems, or hacking resemblance and avoiding the important problems altogether.
So why bother with a low level language like C? With just plain CPython, Flask and a file based approach (including polling the modified dates and thus get live reload) I can get up to ~2500 req/s on localhost with a good CPU, i.e. network is going to be the bottleneck until a fairly high level of performance (at which it becomes a no brainer to scale out).

The behavior is undefined if a value does not match its type declaration, and implementations are free to ignore some declarations, like CLISP. So for a portable approach just add a CHECK-TYPE:

(defun foo (s)
(check-type s string)
(print s))

The main point is that (TYPEP NIL 'STRING) is NIL.

I think people talk about Japanese websites because of the difference between the design of their websites in general and the design of other stuff in their culture.

If you look at landscape design, blank spaces in modern Japanese architecture, minimalist poetry, painting, pottery, film, the websites stand out a lot. There is no "zen" in Japanese websites (again, generally speaking). The "mystic" is how we perceive their work. It exists because it's just hard to quantify art and design. We know something's there though. Famous designers and architects like Frank Lloyd Wright go to Japan and are completely floored. Did many other isolated cultures' aesthetics regularly floor their visitors? People don't get that from Japanese websites... we perceive them differently, without any sense of the "mystic." And that seems odd.

I think it's an interesting question (kind of like "Why is the USA bad at soccer?" which I've heard being discussed a lot before.) but only because of Japan's unquantifiable success in other areas of design.

Also error and debugging are difficult but remember there is an ec2 instance at the end behind lambda. I just mocked the lambda function and debugged on a real server.

Clock drives?

Today's hobbyist telescope mounts have incredible precise stepper or servo motors, many with optical encoders so precise that they know exactly where they are pointing to. I don't think you can get a clock drive anymore.
I don't think std::deque's implementation is specified in standard. It only needs to meet certain running times, and the data structure in the article — the author's "devector" — would satisfy the requirements of std::deque; i.e., the "devector" is a valid implementation of std::deque, I think. However, in practice, std::deque is not implemented this way — your link hints at this:

> As opposed to std::vector, the elements of a deque are not stored contiguously: typical implementations use a sequence of individually allocated fixed-size arrays.

The usual implementation, I think, looks something like the image here[1].

I'm still very suspicious of 'serverless' architectures and people trying to hammer Lambda into fitting that ideal.

Lambda seems best suited for data processing tasks, one off 'cron' style jobs and synchronous request/response tasks that don't execute frequently
I've been a very happy lambda user (using Scala); serverless architecture is really nice. There are some remaining issues (e.g. cold start; although should not be an issue once you actually have decent amount of traffic); many of the issues are getting resolved rather quickly (e.g. API Gateway integration has improved dramatically). I am not aware of any alternatives that come even close to lambda especially if it needs integration with many other services.
