I’m not really arguing against your point, just pointing out that your statement isn’t necessarily true. You said that if you do any network or disk access then validation will be negligible as it would be dominated by that. I’m simply saying that while this is probably true in most real world cases, it may not be so if for example both validation and normal request handling do a simple database query, then validation is 50% of the request time (or 25% if the request takes twice as long etc). Since the person you were relying to above said something about performance sensitivity, this overhead could be too much.

Having said that, I do believe that what you’re saying is the right approach for 99.9% of use cases and I would imagine that in almost all cases the performance hit really is negligible.

My pet peeve with all these time trackers is that... It's just a wrong metric, unless what you're doing is an assembly line equivalent, where you just need to put in the hours.
And don't get me started on such trackers having 'leaderboards' where you're 'competing' with colleagues.
Sorry for the confusion.

I have been most focused on people being concerned that a neighboring VM could suddenly be an attacker. You're right that the same kind of thing that affects your JavaScript engine as a user affects say Apache or anything that allows requests from external sources. However, that situation already has a much larger attack surface and people in that space should be updating themselves whenever there's any CVE like this.

My concern was that the Azure announcement made it sound like they've done the work, so nothing is required. That's not strictly true, even though providers have mitigated one set of attacks at the host kernel layer, so I wanted to correct that.
I suppose "compilation" usually refers to translating source code (as in human-readable) to some kind of byte code (as in machine-readable).

Here, we start with Java byte code which isn't exactly human-readable, hence the use of the term "transpile". But then again, you're right that on some abstract level, it all is just a translation process from one representation to another.

I think this will be good in the long run. If VISA (and Mastercard) end up allowing Bitcoin affiliated payments through their platform, then merchants will end up not providing native support for crypto payments, as they can just use their current infrastructure.

If we want to destroy these payment monopolies in place of a (more, but I understand not completely) decentralized system, we need to encourage merchants to just implement payments directly.

This shouldn't be a surprise, given Softbank is buying from insiders. In fact it would be a poor signal if the shares weren't bought from a variety of individuals who invested early.

Having that amount of money to hand likely means that Kalanick is going to go off and spend a lot more time doing other things. That could also be good for Uber.

According to Statista [1], Uber lost $1.46 billion in the third quarter of 2017. And that is a significant increase from losses of just a billion dollars a year earlier. But, gross revenue for Uber reached nearly $10 billion from July to September of this year. Sounds not bad, however, the majority of the money goes to drivers, while uber received $2.0 billion. Which means that Uber spent about $3.5 billion in expenses to earn $2.0 billion in revenue.

https://newsroom.intel.com/wp-content/uploads/sites/11/2018/... - basically, you need software updates for variant 1 and 3, and both software and microcode update for 2 for certain CPUs. Bullshit doesn't even begin to describe that sentence...

They do not. And more problematically for the "It's all Intel's fault" story, in the SGX documentation they explicitly state that their chips do not protect against side channel attacks and that it's up to the software developer to handle it. As SGX is a part of the CPU effectively that means their official chip docs rule out side channel protection as a feature.

I don't know if playing the blame game here is going to be productive. All CPUs are vulnerable to side channel attacks of various kinds and focusing on Meltdown specifically seems like missing the forest for the trees - especially as ARM has the same issue in some of their designs.

You are totally missing the point. A side channel means that someone else on the same host can read your privileged or otherwise inaccessible data. So it is fine if you only use open source and compile everything yourself but what about that other account on the same machine or image? What about that other VM on the same hardware?
I don't know about you, but the existence of Uber has increased my quality of life. Also, just the decrease in drunk-driving accidents that easy access to rides has brought about is worth a lot. It's easy to see the value Uber has added, and these are just a few easy points. There's a lot more.

There are many open-source solutions for BCI projects like BCI2000 (http://www.schalklab.org/research/bci2000), OpenVibe (http://openvibe.inria.fr/) and EEGLab (https://sccn.ucsd.edu/eeglab/index.php). That's based on the kinds of tools that our customers use. Most of these, aren't as pretty as tool like Neurovis, but in reality most of the information that we make use of to control prosthetics or signal intention involve looking at the temporal-frequency relationships between and within broad regions of the brain. There isn't a lot that you gain from just looking at the brain light up like this for BCI — the main use for a visualisation like this, is as the docs say, for diagnosis and determination of epilepsy since in epilepsy the activity you'd see is much higher than usual.

EEG has better temporal resolution than FMRI; you are measuring the electrical activity rather than vascular changes, the former changes more rapidly than the other. EEG, however, is just the surface activity of the brain, so you don't get information about 'deeper' (physically) brain processes; this is where FMRI is invaluable. EEG is also limited to the size of the electrodes and how many electrodes you can physically place in one location. 256 electrodes on an EEG cap is about the limit you can get to.

Electrocorticography (ECog) involves implanting electrodes on the dura, this can substantially improve the density of electrodes in a given area, however this doesn't measure deep brain activity and we have no way of leaving the electrode grid in place for long periods of time without risking infection. For BCI, we've been able to classify more classes of data using ECog than EEG — research by Kyousuke Kamada and Gerwin Schalk are informative. It's a very promising area if we can work out how to implant the electrodes, seal the skull and telemeter data out.

Magnetoencephalography (MEG) can help with measuring deep brain activity, but there are other tradeoffs to consider. Essentially, the point where we are now is combining multiple techniques to get the best temporal, spatial and frequential compromises.

Thus in answer to your question; no FMRI is not great for realtime responses, measuring the electrical activity has better temporal properties so EEG and ECog work better here. Sensor density is part of the problem, but once you solve density you then need to consider how you'll deal with deep brain measurements.

How Ethereum Smart Contracts Work
System calls have been more expensive with Meltdown. How to avoid them?
This thread turned into eero versus Ubiquiti, but swap the brands and it’s the same Rorschach’s test as iOS versus Android.

The eero system is to WiFi as iPhone is to mobile. Either you want to fiddle with your WiFi or you don’t. I used to, now I don’t.

My home needs 3 wired hubs and 6 wireless/mesh extenders. Used to do it with flashed Linksys gear, then with AirPort Extreme plus Airport Expresses (for one relay hop, this worked very well), now with eero v2. The time I saved with eero is remarkable.

- - -

== Mini-review - Eero v2 + Eero Beacons ==

Location is 7,500 sq. ft. and 4 floors covered by 1 eero gateway wired hub and 2 relay wired hubs, 6 meshed eero Beacons, and the eero iOS app.

Setup took ~5 mins per device. Entire mesh self-updated in one go after setup.

And then it all ‘just worked’.

Wired network gets full uplink speed (235 mbps down, 35 mbps up, in my case). Wireless network maxes out at each device’s speed when direct to hubs, only mild drop off connected to eero Beacons.

Roaming is seamless, handoff quick, iOS app shows which eero base or eero Beacon each wireless device is using.

App has all the ‘advanced’ network config you actually need, tons of detail per eero and per connected device, and you can manage individual devices. You can nickname things to better keep track such as when using dozens of smart home devices like thermostats.

The philosophy of doing by and large the right configuration choices for the user worked out well. My tenants are raving about the new network[1], were able to start using WiFi calling reliably on their Samsung and Apple phones.

Apple should just buy eero.

Footnote 1: To be fair, tenants had disconnected the happily working Apple mesh in favor of D-Link because their cable guy told them to. But the D-Link wouldn’t handoff as they roamed the house, so the D-Link experience was especially bad.

Momentum builds for open-source processors (2001)
I guess it's not really the point, but I'm intrigued to know how a lawyer can spend $260,000 on a gift for someone they don't know.

This also reminds me of reading a story about the olympics style event organised for disabled veterans. The article included a conversation between an Afghani amputee and a british counterpart:

" One day at the games, Azimi, whose lost hand was replaced by a 25-year-old hook, saw a British athlete with a prosthetic leg and asked him what it cost. The British athlete didn’t know.

“You have that leg and you don’t know how much that costs?” Azimi asked him. “Maybe $50,000 or $60,000,’’ the British athlete responded. “Our government pays for that.”

Asked about the disparity between the first- and third-world teams, U.S. team captain, retired Army Capt. Will Reynolds, said he was appalled.

“I’ve got eight (artificial) legs — more than I need,” said Reynolds, a leg amputee who was enjoying a moment’s rest with his son watching the U.S. team practice wheelchair volleyball, after winning medals in cycling, track and field. “Some of the legs I can’t even wear. And to know there are other servicemembers out there wearing stuff that’s not serviceable is unacceptable.”

What makes me certain it's a bubble is all the stories my wife tells me of people from her native Malaysia. Her mother wants to buy in, her mothers friends want to buy in, people take out their pension funds for it, a guy sold his profitable albeit small restaurant to go all-in on bitcoin and so on.

Now it's somewhat understandable given the fact that Malaysias currency has not been very stable in recent years and people are struggling. But people investing all they have into such a volatile market is going to lead to a rude awakening.

I agree with helping people, especially those burned out because your own management pressured on them. And it is also true that a lot of demotivation happen when management is bad and those people start working good once they are in better environment or more suitable position (it positions are not made equal and one can excel in one and fail in different one).

But sometimes, laziness is the thing.

My original point was meant to be that as long as you think about out productivity, have somewhere back in your mind that something should be produced today, you are fine and not in that worst performer category. Because you are trying and that will keep you away from such fall. It was meant to be reassuring in some way.
It is true that the only thing asserted under penalty of perjury in a DMCA notice is that you are or are authorized to act on behalf of a copyright holder. The rest of the notice is not made under penalty of perjury.

The notarized statement comment was hyperbole to make a point about how hard it is to prove, sufficiently for a court, that someone "knowingly" and "materially" misrepresented information in a DMCA notice in order to trigger 512(f). In the Diebold case you had the perfect storm, because Diebold's lawyers basically admitted to the court that they knew they were using the DMCA not for copyright enforcement but to take down something that embarrassed them. That is literally what it took to get a judge to nail someone for DMCA abuse.

And even then: the judge only found that they knowingly/materially misrepresented for a subset of the material, and they only paid out $125k, which is literally nothing to a company of Diebold's size.

Meanwhile, DMCA abuse remains routine and rampant today, in large part because it's next to impossible to get someone penalized for it.
