Packagepeer
Packagepeer is a network which connects online shoppers with neighbors who volunteer to take delivery of goods in their name for a fee. Online shoppers can search their neighborhood for packagepeers, amongst which they can choose their favorite based on rating, other user comments, proximity, pricing etc. Packagepeer covers the entire process through its website where both types of users, the online shoppers and receivers, are registered and put in contact with each other. Once the contact is made and found suitable, the user can access the packagepeer’s details to use them as the delivery address when purchasing online. Then, online shoppers can pick up their goods from their neighbor’s house at their most convenient time and pay a small fee in turn for their neighbor’s service.

Benchmarks for React tell a different story. It's like two orders of magnitude slower than multiple alternatives. If you are performance critical, React is not possible to use in production, and likely will never be considering Facebook's development practices.

Note: They are not closing the flipkart online portal, but they are closing the myntra website which they acquired an year ago. And in the press release they must have mentioned that they are moving completely to mobile version.

They bought myntra because of tough competition and have to close it anyway. They are doing an experiment by keeping the mobile version.

Slow death for Myntra! PR for Flipkart mobile app!
This is a bold take on a problem that a lot of people have written away as reinventing the wheel. But color me impressed!

Unlike almost every other Javascript framework we've so far seen, FOAM makes the data model the primary entity in the system, which is a good idea. In the typical UI-driven development of web applications, the data model often gets modified without much thought and causes cascading complexity across the rest of the system. A lot of the convoluted UI code that I've written could've been kept simple by keeping the data model sane by finding and utilizing equivalences, making implied meaning explicit by extracting names, and normalizing/denormalizing the data appropriately. A data-structure driven development approach should help a lot here.

FOAM also implements another item from my wishlist: being able to see all the UI representation of any given piece of data in one place. It achieves this by keeping all possible templates for a piece of data directly in its object. (http://foam-framework.github.io/foam/tutorial/4-templates/)

In general, this looks like the most declarative (as in, define your business requirements instead of writing imperative code) way of building web applications that I've seen yet. I would like to see what new ideas this library can bring into the 'Perfect UI Framework' conversation, but past experience makes me skeptical of any implementation that overly relies on metaprogramming. Metaprogramming can take us maybe 50% of the way home, but programming unfortunately is often an art in the minutiae. UI code is especially prone to this problem: things that have to deal with humans cannot be absolutely symmetrical all the time, which is where any overly declarative approach to building software breaks down. I often look back to this quote by DHH as a reminder of the dangers in generalization:

On the surface, the dream of components sounds great
and cursory overviews of new projects also appear to be
"a perfect fit". But they never are. Reuse is hard.
Parameterized reuse is even harder. And in the end,
you're left with all the complexity of a swiss army
knife that does everything for no one at great cost
and pain.
- DHH ca. 2005

Also, template based UI frameworks are IMO a relic of the past, of which I'm convinced by the way templates are defined imperatively using code in React. In templating, the UI is a String, but UI should be Code because code is awesome.

I've deployed two applications to production that use React and in neither has React created a performance bottleneck. Both of them are heavily used in mobile, too. And they work wonderfully.

It does not seem a new thing, rather an old one just migrated it to Github.

It has 8,474 commits. The first commit (and also the first issue on Google code) dates back to Jul 30th 2012. And it was just the first public release, not an empty commit (43 files).

I'm pretty certain none of this is true. It's frustrating that people can collect easy upvotes for writing innuendo like this.

It is quite possible to read 500 books over 100 days as a secluded teenager if one is reading mostly 200-300 page books and most of the books do not require perfect attention to detail.

A proficient reader can easily read 2 pages a minute, so lets say 1200 pages/2=600 minutes, so 10 hours a day. Seems quite doable for a bored teenager without a computer/tablet/phone/outside activity.

I don't think I ever did more than 3 books a day, but still possible to do what OP said.

I think many/most of us has have read a page turner in one late night session.
I've done this before, and nearly every time the person has said to me "Oh, I haven't read a programming book since university. I do all my reading online".

It seems to be a common thing, which is a shame. I've always been fond of books, and unless you're pirating some classic texts and reading them as PDF's on your computer it feels like people miss out on a lot of quality content.

How often do you come across this? Admittedly, when I've been directly involved in interviewing this has almost always been for people under 25 coming into a junior level role.

Yeah, skepticism makes sense. But "The New Turing Omnibus" and (IIRC?) "Programming Pearls" are structured so you can read them in bite-sized pieces. In fact, the books on this list seem unusually readable; at least the ones I've read.

And "The New Turing Omnibus" seems really under-cited to me. Maybe same with the "The Little Schemer" (and successors like "The Seasoned Schemer").

That said, all these books also have necessary flaws. (After all, they're single-author and in print; you can't build on most without law enforcement trying to come after you.) A good review would list negatives as well as positives.
But the reason they break code compatibility or implement older versions of the architecture is that parts of the ISA are patented by MIPS. Other ISAs like OpenRISC, SPARC and RISC-V don't have these limitations.
A few calculations about the possible explosion:

- Assuming the inside of the thermos is at room temperature (and that there was enough dry ice initially), the pressure should be around 60bar. This is the vapor pressure of carbon dioxide at room temperature [1].

- At 60 bar and with a volume of, say, 1 liter, the energy available for the explosion is roughly 60bar x 1liter = 6kJ [2]. This is a TNT-equivalent [3] of about 1.5g, or about 10-100 firecrackers. Enough to cause injuries, but not enough for structural damage to a balcony [citation needed].

In my personal opinion, the most dangerous thing was handling the thermos. I believe letting the thermos sit on the balcony for a few days and closing doors and curtains (to prevent glas shards flying in) would have been a much safer alternative.

That's great. I'm more surprised that there was an European country without a mosque!

I don't like the undertone of "farewell" and scare-quoted "conquered", which is implies we're losing something and muslims are taking over.

We have freedom of religion, and European citizens who believe in Islam, so there should be absolutely no problem in having mosques.

It works because too many startup entrepreneurs don't understand what "getting feedback" actually means.

A stand at an event designed for startup entrepreneurs should only be a valid incentive if your market is startups. If you're doing anything else then you're marketing to the wrong audience, which is a huge waste of time. Feedback only counts if it's from potential customers, or better yet, actual customers. Having 1000 people file past your stand saying "That's really clever and innovative" is a great ego boost - but that's all it is if they're not people who will buy what you're selling.

When you're building a startup you should only spend money getting to events where your customers are going to be. Go to those (often quite boring) events and sell to people. Being in the same room as a startup celebrity is far less valuable to your business than a even one single paying customer.

If you do that then you'll have no problem meeting investors. In fact, they'll come to you.

You should have seen the shambolic mess of a Python script I inherited from a colleague. The script was doing bash calls, to call itself with different arguments. Functions generating functions, not because of any high level of abstraction, but because she didn't know how to write a module. The code inside was more complex than fizzbuzz, but the way it was shipped was beyond terrible.

Coding something like fizbuzz is usually day one of a programming course. Using modules maybe day 2 or 3? I would see it as a sign of a more mature developer.

As the author of the tool, I can share that these tools are still very much needed. Why? Upstream vendors will never set values that are strict. Because in that case, people would have too much difficulty to get things working.

The tool exists to simplify testing many individual tests. We don't simply use existing benchmarks or guides, but also have tests of our own. For example, if you have configured at least two name servers, or that your time is properly configured, and no false-tickers are present. Things which no upstream vendor even can configure for you.

Another common use case: you are the new system administrator and have to deal with the "great" work of the previous one. The tool helps to determine the quality of the previous person, in just a matter of minutes.
>>Older, serious, and timeless literature requires deep concentration because the authors use their thousands of words to express deep pathos that can't be trivialised. It takes practice to commit oneself to a book like that for long enough to get into a flow wherein it can be understood and appreciated.

Literature that must be studied to be understood, that must be decoded, that the author spent years on, cramming endless meaning into every last sentence...

This is not fun to read and never has been, even before the age of digital distraction. I don't aspire to read 'great works' that can only be decrypted if you have a degree in literature, in fact I don't think that sort of literature is objectively any good at all - it self-limits, it speaks only to the cognoscenti, and misses out on speaking to everyone else.

In even dimensions, volume of a sphere of radius 1 is:

For 10 dimensions, the hypersphere is of volume 2.55, but the enclosing box is of volume 2^10 = 1024. So roughly one in 400 trials gets you a point inside the sphere. Not good odds.

Yes, that is true. MIPS Technologies held patents on the MIPS ISA and most of those were transferred to Imagination when we completed the acquisition. However, many of these patents are also owned by an internationally-backed consortium which includes ARM:

I think this announcement is particularly important because it gives students the chance to study a piece of RISC history. When I was in University studying for my Electrical Engineering degree, we were asked to clone an 8-bit MCU. While it was a useful exercise, everyone was dreaming of seeing a fully open MIPS CPU. We were taught it yes, in the Computer Architecture course, but never got a chance to see any RTL code.

RTL code + slides beats slides in my book so that's why I feel this announcement is so important for me, personally - but also for universities worldwide.

North America was inhabited for thousands of years by the time Europeans arrived and land tended to be managed as a matter of living on it. The thick forests early European colonists encountered were the result of massive depopulation of people and not 'natural' in that sense.

The idea of setting aside land for unmanaged old-growth forests is a modern one and we're likely seeing it again for the first time since early colonial times; back then it was inadvertent.

We're currently evaluating options, but for .NET Serilog is shaping up extremely nicely, and Seq/Logg.ly as log sinks are nice...

Seq is great because you can set up your own instance very near to your servers for low-latency/high-bandwidth logging, which really changes the game in terms of what you can feasibly (perf/financially) log. It also has some decent visualization options, and it's got some great integrations, with a decent plugin architecture to create your own real-time log processing code.

Logg.ly has some amazing GUI/search options.

I can understand your frustrations, it does seem huge amounts of the work in a web application are really about configuration rather than code. Often there are no algorithms, just lists of database tables and fields, forms, validation rules, routes, links, templates etc.

I agree that public servant unions generally have too much power. However, I'd like to hear more about your theory about how police unions have leverage over judges.

Firing someone is much different from not throwing out a court case against them. I can see how police unions have a lot of leverage over the executive branch, but I'm not sure how they extend that leverage over the judicial branch.

This quantity is absolutely nothing. Area of the single forestry, let's say in small Latvia is around 30 000 ha. 1Bn, I assume, is EU milliard. So, drones can plant, say pine seedlings with density of 4 thousand/ha (which is IMHO insufficient), which gives capacity of just 9 ha/day! I can't see anything industrial in that. Chinese mainland reforestation programme plan was 4 mln ha/year 20 years ago. Belarusian Soviet reforestation bot PLA-1 (Designed in Homel) was able to make 12-24 thousand plantings per hour in ... 1977!
What is good in aerial drones - you do not need to remove tree stumps. Makes the whole operation real safer and cheaper. But its capacity is still vary far from industrial requirements in reforestation.

I wonder how many HN readers have amateur radio licenses?

I got one last month (AF7PL). Now I'm working on getting a radio. I don't want to just go out and buy something. I want to do this old-school, and so have at least some of the major components of my shack home built (and ideally home designed).

I may partially relent, though, and buy a handheld transceiver for 2m/70cm. My electronic construction skills are pretty primitive, and my oscilloscope (unlocked Rigol DS1054Z) only goes up to 100 MHz, so VHF and UHF radios are probably out of my DIY league. That's fine, as I'm actually more interested in HF anyway.
That would be true in any big software project, and in any complicated system. Regardless of how many reboots will there be, systems that are simple enough for an ordinary developer to fully comprehend can not complete the tasks we want from them.

> to people saying the cap is the weak point: 9/10 times it's the bottom that gives in first.

It may be the case for a typical water bottle but thermoses have much larger caps. The maximal force that a cap can hold is proportional to its perimeter (~r), the force itself is proportional to the area of the cap (~r^2) and the pressure. So larger caps can blow off by lower pressure. I would bet that for a thermos the weak point is the cap.
