I would be also interested in mini vacuum packets, that one could strap to their car or backpack, and make it a touch lighter.

Just imagine the energy savings!

While exodus is a good minimum bar, and I use it, its list of detected trackers is incomplete. I have reported two known trackers, but their signatures are not yet detected by exodus.

It is difficult to know these signatures because the good trackers share their SDK only under an NDA.

Try flatpak with flatseal

The permissions are not interactive, you can set them once and forget.

That's why Matrix is better. Open server, open client, open protocol.

Host your own server, build your own client, and yet be able to talk with everyone else.

For the first problem, you need to ensure that you exercise the muscles along with fasting, to nudge the body away from salvaging proteins from muscle tissue. (Not a bio chemist either, this is what I have read in most articles about intermittent fasting)

What has been the amount of devaluation in USD, post covid?

Is there a ready number we can just plugin to recalculate the value of one's assets?

For example, if I held 100usd worth of a stock in March 2020, what would its worth be in Jan 2021, just due to currency devaluation?

> But there really is need for another browser engine. If alone to prove that writing a new one from scratch is possible in 2020.

We have been developing one here [1]. It's a long way to go, but hey, it's open source!

And we had found it working fine on a RaPi 2 couple of years back.

htmx sounds great! I am interested in this from the security angle. If browsers were to natively support htmx (or something similarly declarative), it might reduce the need for Javascript and hence improve security.

Agreed; a determined programmer could solve almost any Captcha given sufficient time and resources.

But we are not trying to create an unsolvable Captcha. For those websites that need something good enough to deter generic bots while not compromising privacy of their users, this might be a good enough alternative to reCaptcha.

Imagine a docker image which just works with out-of-the-box generators. Those who need more variety could create a custom generator with Javascript and drop it into a docker volume.

Would appreciate thoughts on this alternative that we are developing:

https://github.com/librecaptcha/lc-core

The idea is to develop a framework for Captcha generators. A few sample generators are provided out of the box, but new ones can be written easily. The framework takes care of storing entries in the database, serving them as challenges through an HTTP API, and checking the responses.

From the README, why libreCaptcha:

  * Eliminate dependency on a third-party
  * Respecting user privacy
  * More variety of CAPTCHAs, tailored to your audience

The implementation has a long way to go (it was written by students trying to learn Scala), but would appreciate thoughts on the concept.

GC should be available in WASM in the future. And, not all applets needed JNI.

In other words, this is enabling a subset of well behaved applets, while excluding the naughty (or advanced) applets.

We don't need a new web; just more browsers that respect the user's privacy. There are many ways to achieve this. At gngr[0], we are taking a "safe by default" approach. This is very similar to the NoScript / uMatrix approach, but with one difference: the browser itself is offering this and is hence more water tight. There are no behind-the-scenes requests that a plugin can't block.

> I'm not sure if it's still this way, but Chrome used to load every tab on startup.

I used to avoid Chrome for the same reasons, but then I found an extension and, uh, extended it, to create:

https://github.com/hrj/sloth/

It forces all tabs into inactive state on startup. Also creates a new tab page (or switches to an existing one) to avoid loading the focussed historical tab.

I got confused too.

We can't stop people from naming their projects/products the way they want. However, I think headlines in HN should be editoralized a bit to provide context, followed by the actual headline from the webpage.

New comment by hrjet in "A first look at WebAssembly performance"

hrjet — Thu, 09 Feb 2017 11:04:30 +0000

You can try increasing `N` in the nbody problem, and also measuring the memory overhead.

You could also try one of the hashing / crypto algorithms in JS. They should involve a lot of integer arithmetic that should make WebAssembly stand out.

More tips:

* for performance measurement, setup the benchmark so that JS run takes atleast 30 seconds. (Increase N, etc)

* close all other applications and tabs

* If you have linux, set the CPU governor to performance

* Measure the CPU temperature and make sure you let the CPU cool down between runs. In modern CPUs, the cores get throttled automatically when they reach a certain temperature.

New comment by hrjet in "Apple proposes new web 3D graphics API"

hrjet — Wed, 08 Feb 2017 06:56:45 +0000

Thoroughly solving security problems would of course take time. But the parent comment asked a very high level question: How does the security of this new proposal compare to a client-server model such as that of OpenGL? One can simulate one model over another, but in that case, performance can suffer due to overheads. This sort of thing needs to be addressed at the outset, because graphics needs performance and the web needs security; neither can be compromised upon.

hrjet — Wed, 08 Feb 2017 03:36:31 +0000

Why are you proposing a new standard when you are still thinking about security?
