Ask HN: Why are some webpages sending double content?
I've noticed recently that some sites (for example: https://www.aerofs.com/blog/) seem to duplicate the content on the page.

The formatting makes the rendered page only show it once, but with some elements (cookies, Javascript) disabled, or just by viewing the source, it can be seen that the content appears twice.

Is this the results of a certain content managament system, or a particular framework ?

I can't imagine that sending double the content is particularly beneficial.
Oh man I wish I was. Those games were practically life changing as a child. At one point my parents moved our computer into the bedroom to stop us from playing all hours of the night. They then woke up on a Saturday morning to a friend and I sitting on the edge of their bed playing. That did not go over well -- but they did move it out of their room after that!
As well as logging that ticket publicly in case anyone had a contribution to fix the issue gitlab was contacted through the paid subscribers channel and their response was that they would follow it up on that public issue. I don't have an issue with that so let's wait and see A) what the fix is and more importantly B) what lessons were learnt from the regression.

Here's a prediction of how this conversation is going to go:

1. This stuff isolates specific functionality into a hardened component!

2. You can run an existing program as an isolated, hardened component!

3. You can run all of your programs as iso., hard. components! The parts of your system won't be able to step on each other except in well-defined ways!

4a. You mean sort of like old-school process isolation?

4b. Blah, blah, blah, Plan 9, blah...

4c. Blah, blah, any virtual machine like the JVM...
I just built a 3D printer (Reprap Prusa i3v) so I could design and build custom parts for a hardware project I'm doing and I think that this is overly pessimistic.

I needed to print, try and tweak parts, if I ordered everything from shapeways my iterations would have been stretched out.

Here is a page I wrote about my experiences:

http://winterstartupchallenge.com/3dprinter.html

The only difficult thing was the calibration, making sure the surfaces were level etc... this could all be drastically improved with better reprap design.

Learning how to design models that could be 3D printed took some time, but now its second nature and basically comes down to not having any overhangs greater than 45 degrees.

I'm really glad I built my 3D printer and have the skillset. My ambition in life is to become what I call Master of the Intelligent Networked Machine, which is a grandiose way of saying I want to have the full skill set to design and build Internet of Things devices, from the hardware to the code.

I think its the most valuable skillset around today and 3D printing is a valuable part of the toolset.

It took me time to build the printer, but in the process I learned about the technology and I immediately saw the possibilities for using it in new and interesting ways. By seeing how a RepRap is built (commodity parts + custom home fabricated parts) it changed the way I designed and built my hardware product.

Becoming a 3D printer master builder only took a couple months and was well worth it.

It’s Time to Elevate IT at VMworld 2015
I gave up on my home state barely a year ago. When I graduated from Wichita State there wasn't much in the way of actual software developer jobs in the city or even up north near Topeka. It was fairly depressing to have to accept a job out of state since despite all its flaws it's my home. But since I can't find real work back home and the fact it seems the state Republican party is hell bent to run out any business that doesn't follow its status quo (especially companies who are LGBT friendly/inclusive) I won't be coming back other than to bury my parents.

Maybe someday I'll come back to my home state but only when the madness in the state capital has ran its course and actual competent politicians are at the helm. Until then I'll be working up here in Minneapolis Minnesota (even though I hate the traffic and the winter weather... BLEH!).

We use Redmine for ticket / issue / task tracking as well as rough timesheeting, and we use gitlab and gitlab CI along side it. I quite like how quick Redmine is and how it just gets out of your way. We find gitlab to be pretty quick however upgrades are painful due to regular bugs / regressions.

> What Yelp wants, is to have their cake and eat it too.

That would be true if Google didn't have an effective monopoly in search. Because it is an effective monopoly, saying that about Yelp is like saying a citizen that is against any form of socialism but cashes social security checks wants to have his cake and eat too. False. That citizen would prefer that social security doesn't exist, but given that it does, and given that he is forced to pay the costs, isn't going to be stupid and refuse the checks. And I say that as a free-market socialist.

There are two ways to deal with a monopoly:

- break it up

- allow it to continue, but force it to provide equal access, at non-monopolistic rates and terms

How long do you think Workflowy took to conceptualize and implement?
I don't think you'll find anything useful looking at "grand challenges" or other such lists. Problems get on such lists because they are hard to solve and because they require significant resources.

A better approach might be to find a slightly technically backward field, learn about it in detail, and then apply modern technology to improve performance or lower cost. I remember meeting a guy, years ago, who had made a fortune inventing a new high-tech way to remove the casings from hot dogs.

Finding an appropriate problem to solve is part of the problem.

They are significant in number, not in capitalization.

This is the Innovator's dilemma. If you don't consider a cheap or toy market that is 10 times bigger than yours in units sold and continue growing as "significant" then you will find yourself on a "kodak moment" soon in the future.

It is very much the opposite. With this pattern, you're going to have lots of copies of your data in different transformations in potentially many different data stores. The idea is that you take the stream of changes from something like Postgres and use that stream to populate caches, indexes, denormalizations/representations, counts, etc.
Good questions. It supports collada which is the default ascii format por scenes, i managed to export complex scenes with animation without problem but there are some cases that do not work.

Performance could be improved, im aiming more to flexibility but i managed to have hundreds of objects with independent materials at 60 fps. For mobile i want to create a lightweight rendering mode because the current one has too many cases to consider.

The next release will be focused in bugs, and the one afterward in performance.

Arguably there is - you can boot these AllWinner chips using entirely open source code, whereas you need a binary blob to boot the Pi at all and the license agreement forbids you from using it on non-Pi Broadcom hardware. Also, the USB interface on the Pi is third party IP from Synopsis that - last time I checked - they can't document, it's incredibly buggy, and Ethernet goes through it too. (Whereas the AllWinner USB host interface is standard EHCI, just like an ordinary PC.)
1. Do you have a source for that claim? You probably only run into a significant lack of variation if the gene pool is extremely small, i.e. in incestuous relationships.

2. As far as I know this is not fully known yet. It is conceivable that the offspring did just fine in polygamous relationships or just inside the secure environment that the pack provides. There is, for example, some evidence that intensive mothering is ineffective [1]. Among Great Apes the upbringing of the young is commonly shared between the members of the pack and the identity of the father is unknown. Moreover, consider that the importance of education only became really significant within the past 100-50 years, or so, but the concept of marriage in Western culture is much older than that [2].

Graphs That Showed Landmark Discoveries but Were Later Debunked
I see a lot of responses that seem to reflect what I consider a misunderstanding of the real advantage of speed.

It's not to get the same amount of work done in a shorter time (the management fallacy referenced in some of the comments).

The point of speed is to increase the number of feedback opportunities. Each feedback datum allows for slight course corrections / confirmation of original hypothesis.

By analogy, think of it like sample size. If you accept time as a primary constraint, then faster iterations (even if you accomplish less!) tend to give you more samples. More samples mean less variance.

Making decisions on a better model (less variance) is very appealing to me.

Hi, I'm the founder of SourceDNA. We've built an index of the code in iOS and Android apps to quickly answer questions like this about how they were built.

TLDR; we created a tool that lets you just search for an app and see if it's affected.

https://searchlight.sourcedna.com/search

In this case, the Android NDK does not include OpenSSL and considers it a private API, so developers have had to come up with their own approach. The correct one is to statically link your native extension with your own copy of OpenSSL or include a dynamic (.so) copy of it in your APK. But some developers were retrieving the library from a random Android device to link against, but then relying on the OS to provide exactly those same symbols.

Even more painful is that native libraries that were pulled into your project by some other dependency can also cause the same issue. For example, Baidu's push messaging plugin depends on OpenSSL for crypto, so you wouldn't even know you were affected by this problem just by using it.

Affected apps will continue to work fine until run on the newest Android devices with Android M, such as the Galaxy S6, Note 4, and Nexus.

We scanned our index for apps that had native code, matched each app's binaries against libcrypto.so and libssl.so, and built a graph of each dependency linkage. Then we could trace the graph to find apps that had this flaw and exactly which of their libraries was at fault.
That was kind of my impression, from the discussion in Alexander Stepanov and Daniel Rose's From Mathematics to Generic Programming (which is a pretty decent book, by the way).

My understanding[1] is that concepts act like a type system for templates and like typeclasses in Haskell and traits in Rust.

Let me turn that question around a bit.

Part of the art of being a successful solution provider is having the expertise to identify a problem in the first place. Usually that comes from having a lot of experience in that industry already.

I know this doesn't directly answer your question, but bear in mind that you have a bunch of saleable skills (otherwise you wouldn't have thought of this already) and you're willing to apply those skills in helping people who are willing to pay for them.

Also, we have a tendency to ignore the things we're already good at in favour of the things we've most recently become good at, so when you start narrowing your focus and zoning in on problems you want to solve, you might ignore some of the things people might find most valuable in your skillset, however long ago and intellectually uninteresting to you those skills are. Remember, solving business-level problems is more about your overall viewpoint of the industry and how its bits fit together, not about tickling your own brain with this month's interesting JS framework.

So, as a really bad example, you might have written a bunch of task scheduling/interleaving code to drive PLCs on a production line a few years back, and that might not be interesting to you anymore, and you might also have become really good at hooking Hibernate up to replace a bunch of badly-handwritten SQL after that, and again, that's not interesting anymore. But, if you really know automation and enterprise app ORM, you might suddenly find something that people are willing to pay for.

I'm outside my depth here, but isn't that what hierarchical learning is? (I think it's popularly called "deep learning", which I assume means the neural nets have depth?)

From what I've read, we aren't going more than a few dozens of levels deep. But it also sounds like this technique is very successful in image recognition.

Am I incorrect in my understanding?

My initial read of this story is the same as yours. If accounts are to be believed, these suspects are violent and the police have legitimate reasons to be after them. Bringing this as an example does injustice to those with more legitimate concerns over police surveillance.

Then I start playing devil's advocate. They don't know this guy is a cop initially; if they did they probably would have been deterred by the risks and stiff penalties involved in harming law enforcement. They also didn't kill the cop even though they had ample opportunity to do so: they wave weapons at him, they shoot him nonfatally in the arm, they beat him up, but this may be because they saw his gun and saw him as a threat. The suspects have clearly committed crimes against the cop but it's less cut and dry whether they would have done the same had the officer done something differently.
You can view government as an imperfect tool that attempts to achieve the impossible goal of justice, or your can view government as the definition of justice.

It's a question of whether to judge an imperfect tool based on details of how its mechanism works or whether to judge it based on how well it performs the tasks we ask of it.

I'm just saying that within this focus on microtransactions above all else the overall goals are lost and the balance of penalties is wrong. When the government goofs, we let the criminal go and deny the victims justice. The purpose of the justice system is justice. The focus on these microtransactions elevates government as the definition of justice which seems much more expansive than the alternative, IMHO.
Surprisingly little talk here about the degree to which Google has abused its search market position in ways that push other players out. I would have expected more. Antitrust laws exist for a reason. If Google uses its dominance in search to stop better solutions from having a chance, it hurts everyone--consumers included, but startups especially. It's not just a matter of "protectionism," it's a matter of keeping the market open to innovation.
