One thing to keep in mind for how development at larger tech companies works is that you’re often not building on your own desktop, you’re usually building on a development server that’s on a well-connected (effectively production-quality,

Since you mention a big tech company, what you’ll probably find is that there are people that care about these things around you, and they’re probably doing what they can and could do with support - not necessarily to do work, but also just

Perhaps the right word is “system” - the combination of software (DNS protocol server software, health checker, BGP agent, and so forth) involved in making the DNS service available (or not, in this case). These could be running on the sam

Stories (which is the medium used) about how things went right without effort are boring. Which leaves two stories - things that went right that had a lot of effort, and things that went wrong. In the case of things going right with a lot

Her stories gain a sharper edge if you’ve worked in similar sorts of environments before. If you aren’t aware of how there are teams trying to “own” turf, and prevent alternatives (even one-offs), and also how the entire company tries to fu

At FB, most ICs are not hired for a specific team in advance, and instead choose between (for SWE, a long list of) teams during the Bootcamp process. You can chat to future team mates (not just manager or lead) and ask them straight out ab

Keep in mind that the referenced paper that this page is based on is over a decade old now. Many things have changed since then, as you can imagine. Look for later papers and engineering blog posts for more about what’s changed since then

In some ways, HTTP 3 is the same HTTP messages, just over QUIC. But as you get into other features, there are differences. And your clients and servers need to both have fallbacks to HTTP 2, since UDP connectivity might not be available, a

The main benefit is multiplexing - being able to use the same connection for multiple transactions at the same time. This can have benefits in finding and keeping the congestion window at its calculated maximum size, reduce connection-rela

Even in the proxy case (which is my day job), it's often worth the price of the up-front load polling to have sufficiently recent information to take action on. The most obvious cases are those where you have some (or all) requests be

Your job title/level/rank (“Principal Engineer”, “IC6”, ...) is what you’ve been deemed capable of (usually by doing it). But your role on a particular project is going to depend on what’s needed. Sometimes you’ll be the lead of

TCP has an explicit client and server (some caveats here). The userspace API for TCP requires you to do a connect, which does the TCP handshake in the TCP stack, before you can send traffic. For UDP, you just specify the destination IP and

Pretty much any HTTP proxy supports talking a set of negotiated protocol versions/features with the client, and a potentially different set of protocol versions/features with the server behind it. The high-level flow is pretty muc

Yes. The Internet-side client and the proxy server can use different protocols and versions that they can negotiate however they like, receive the HTTP request over those, and the proxy can use a separately-negotiated connection to your se

The “US Tech Workers Union” doesn’t appear to be a union at all. It appears to be a subsidiary of the “Progressives For Immigration Reform” non-profit aimed fairly exclusively at the H-1b issue, and the only spokesperson I can see for it i

There’s a free demo version (on the same page where you can buy it), although that doesn’t allow you to exercise the customization via C++ code (which is perhaps one of the most intriguing parts of the editor).

It’s easy to take a statistical summary of two groups, and discover that attribute X has some distribution for one group, and another for the other. But figuring out why requires much more effort. In order to say something is genetic, you

Or, perhaps, much less magical non-genetic factors like more likely being brought up with less access to higher-quality education, nutrition, stability, and safety. Here’s an article from the institution whose graph you reference about why
