How well does it deal with video/image content? My timeline occasionally jumpscares me with gore/graphic/political content.


We are going to support images in the next version we release (ETA 1 week), in terms of videos not sure how we'd be able to do that currently but constantly experimenting. Have you tried the extension yet?


No I have not. This is the killer feature for me though. Text based stuff I can just ignore or block, but the videos/images are what actually bother me (the abundance of porn on the site is what prevents me from using it in public).


> Obviously founders can't keep running a 2000 person company the way they ran it when it had 20. There's going to have to be some amount of delegation. Where the borders of autonomy end up, and how sharp they are, will probably vary from company to company. They'll even vary from time to time within the same company, as managers earn trust. So founder mode will be more complicated than manager mode. But it will also work better. We already know that from the examples of individual founders groping their way toward it.

What was the point of the article? Don't delegate important decisions to the people below you, except for when you do? What PG is suggesting is a founder should understand all problem spaces the company exists in, better than any other employee in any position, in perpetuity, because no-one could possibly understand anything better than the founder. If you want labour to scale, you need to let people actually do their job.


> Achieves 94.9 Mbit/sec when Pico is overclocked to 300 MHz, as measured by iperf

Is this an effective rate, or just the reflection of a hardware limit?


A 1500 byte (octet) MTU frame is 1538 bytes “on the wire”.

7 byte preamble

1 byte SFD

6 byte dst MAC

6 byte src MAC

2 byte ethertype or length

46-1500 bytes of payload (ignoring “Jumbo” frames and 802.1q tags)

4 byte CRC

12 byte IFG (which is silence, but still counts for time on the wire)

Add it up and you have 1538 bytes “on the wire”.

TCP overhead for IPv4 is 20 bytes for IP(v4) (no options) and 20 bytes for TCP (again, no options).

So 1460 bytes of data for 1538 bytes on the wire. 1460/1538 = 0.949284

So for 100M Ethernet, 94.9284Mbps is “perfect”.


At Opsec HQ:

Lieutenant: Captain! Captain! You've got to see this!

Captain: What is it?

Lieutenant: We just uncovered an entirely new ICBM design being deployed right now by the Kremlin!

Captain: Really, that's incredible!

Lieutenant: Well, not quite. The fins are attached horizontally, the warhead is placed inside the booster, and the fuselage is an asian woman's face.


Spot on :)

PS. Also, curiosly fins have six fingers ...


I don't understand why these major concerts don't have disposable earplug booths. These things probably cost <1 cent to make. You could 50x markup your supply, they'd still be cheap, and attendees would still have their hearing.


  The most mind-blowing moment, not only for De La Mata but the scientists too, came when they managed to actually record the sounds that she heard in her ears – which now appear as ‘Left Ear’ and ‘Right Ear’ which begin sides A and B on the album – and in doing so opened up questions about the nature of tinnitus itself. “The NHS definition is that it’s a phantom sound that your brain is creating, that it isn’t something ‘real’, so you should try to ignore it.” By having De La Mata place her ear into an anechoic chamber, with an ultra-sensitive microphone perched in her ear canal, they were able to provide significant evidence to the contrary. “After the first recording of it, it was ‘There’s no way, this isn’t possible.’” They tried again with her breath held, and again with her tensing her ears, and again with other members of staff, but each time it became apparent that yes, the noises De La Mata hears are seemingly something physical.
Utterly fascinating. I hope more research comes of this.


Sounds like these could be Otoacoustic Emissions

I wonder whether there might be a bidirectional connection between the ear and the brain. For example, the brain creates some internal activity, which in turn stimulates the more outer components of the auditory system.


I would assume this is completely standard. The ear doctor I went to, and that guy was noone "fancy", did this and that must have been more then 10 years ago.


In my experience, they're actually playing a super high frequency gradient and it's listening for the echo/feedback. It's how they do hearing tests on newborns too.


I wouldn't be surprised if they picked up the electrical signals from the auditory part of the brain.


Could anyone provide an example of what Leetcode problems are too hard or unrealistic for hiring/interviewing purposes?


As someone who loves Khan Academy, who was taught math from it when my High School teachers couldn't, it really saddens me this is the emphasis Khan Academy chooses, instead of creating more material.

The fact is, Khan Academy was so useful to me in school precisely because it was NOT a resampling of a Wikipedia page, of every uninspired textbook I was ever forced to read. It was a smart, real life human being who understood the nuances of how actual human beings understood concepts. Sal didn't just break down complex mathematical subjects for me such that I was able to solve linear equations in echelon form, there was also a particular way he emphasised the words he spoke so I understood why something was important. The human factor is so important, and we're fucking over our next generation for market hype.

A few years ago, I was bullish on online learning. But no-one with common sense is as the helm. I am incredibly concerned that Microsoft is believing its hype at the cost of something that was at one point incredibly valuable to society.


I actually laughed when I read that


The downside of this approach is the redundancy of information. If multiple conversations are happening at once, it's hard to follow what people are saying about a particular one. Following a thread's history means there is a huge amount of cognitive load regarding filtering irrelevant comments and ignoring redundant quotes. By this new method, I will only ever be shown a post I don't care about once.
