I'm actually baffled at how bad reddit's native video player is. For a core part of the browsing experience, it is truly an embarrassment. Here are the behaviors that I deal with on a regular basis: (i) On mobile, I simply cannot

I love this book so much. It is a treasure. You can tell from the text the Remzi and Andrea are natural educators, and their sense of humor makes you want to read more. Years ago when I used this book, I was blown away by the clarity and co

You might mean well, but I find your second point to be inappropriate. I don't think a qualified medical professional would arrive at those mental health outcomes solely based on a short post about Linux + ARM laptops. The lack of focu

Wow, 27 hours of coursework and a thesis! Are you sure you can complete this in one year? That seems like a very heavy schedule. I guess it depends how your department accounts for course credit hours. My department was 30 hours of coursewo

What type of masters degree is it? Course-based or thesis-based? If you are interested in continuing on to a PhD, a thesis-based masters would give you a much better insight. Even better if you try to publish while you are getting your degr

You bring up a solid point. It would be interesting to see, of the students leaving a PhD program with poor mental health, what fraction already entered the program with poor mental health? My hunch is that the stark majority acquired it wh

> The biggest risk factor I've found for a PhD student is lack of research experience during the undergrad degree. Previous research experience might help, but there still are a number of factors that need to align in order to h

Great points. You hit the nail on the head. Once you get 'enough' throughput, getting more doesn't really improve one's mobile experience. Latency is king. CPU / power usage is another big one. It's hard to jus

By 'enabling sch_cake', I meant that I use sch_cake on my wireless router (which I flashed with LEDE). Sorry, I was a bit light on the details.

Thanks for everything that you do, Dave. Your bufferbloat and WiFi work is excellent, and I'm excited for the airtime fairness work with Toke to make it into more 802.11 drivers than ath9k. Cheers.

In my experience, changing the default DNS servers, enabling sch_cake, and minimizing shared spectrum interference are the most significant improvements for a home WiFi connection. Can anyone think of an additional dimension for improvement

Anecdotally, I've seen larger amounts of packet loss and jitter when TCP accelerates faster into a loss event. The small amount of preventative loss reduces both of these values.

That is the talk I was referring to -- and I do agree the material is thin. But here's what I was basing it off of: the userspace networking slide has the "TCP / IPv6" block in userspace. While it's true this could

According to their slides from WWDC last year, it also offers TCP in userspace.

I admit that I exaggerated with my wording that you think Google is non-existent on the academic front. It's unfortunate that your response focuses almost entirely on this one aspect, and not the message my post attempted to convey. &g

> $14B is a lot of money. Even a small slice of that makes MSR one of the most prominent funders of CS research. You are moving the goalposts. I am not saying Microsoft is not a prominent funder of CS research. I am challenging the not

Still, though, MSR is one of the more prolific research institutions in CS. If they were a university, they'd probably be top-ranked. I definitely agree. They have some top notch researchers, certainly. I also agree that the budget c

The userspace networking portion of the talk starts at 46:00. To clarify, the whole networking stack isn't userspace. They still have the classical BSD networking stack. I think the userspace networking stack is used automatically by s

What is your source that Microsoft funds more CS research than the US Government? Let's ignore any DoE, DARPA, or NIH sources of funding, and just focus on the NSF. The computer science portion of their budget is almost one billion do

You are trying to frame people's responses into a "Google good, Microsoft bad" response, and I do not think that is fair to them at all. They are disagreeing with your idea that Google is non-existent on the academic research

I was going to link to exactly the same thing. Only considering these 2017 faculty research awards, that is over $22 million awarded to academic research. Not to mention Google frequently uses the model where professors work at google for a

Admittedly, I am also not well versed in this area. My guess is, because Metal is proprietary, they can include intimate details of their hardware platform to squeeze out the most performance. And they probably would not feel comfortable ha

I disagree. As discussed in the talk, Network.framework is built on top of their userspace networking stack. This eliminates the kernel-userspace context switch and gets rid of one packet copy operation. These are known problems in the sock

I totally understand. You are facing the classic dilemma of privacy vs convenience. Personally, I distrusted facebook so much that I have avoided any of their products since 2013. Obviously a major win for my privacy, but it sacrificed some

With regards to your edit, yes, you are wrong. And I don't mean that in a harsh way, just answering your question. From WhatsApp themselves [0]: "WhatsApp end-to-end encryption ensures only you and the person you're communica

I wouldn't take SiVal's comment as ground truth. I think it conflates rules for general employees with rules for his friend, and mixes it with a dash of unfounded hyperbole (criminal charges?).
