Are you a US Citizen or Green Card holder who has won the tech lottery and has > $100k discretionary income? I know for sure there are some reading. Consider maxing out and donating $5000 to the Fair Fight PAC, and $2800 each to Warnock and Ossoff. Reasons ...
First let's acknowledge that campaigns accepting this kind of money is an insanely corrupt practice way outside of international and democratic norms. It biases everything towards the donor class. So please don't expect anything in return ... except a functioning US democracy.
The US electorate have voted overwhelmingly for a democratic government. Huge popular Democratic Party candidate majorities for presidency and house, potentially even the senate. But that may not be the actual government we get.
The US electoral system is undemocratic and tipped heavily in favor of inaction and gridlock ... made even worse by a radical and partisan supreme court. People vote over and over again for better healthcare, better climate policy, and more justice ... and they don't get it.
This is toxic and corrosive and creates cynicism and destroys credibility in the system. It benefits only an elite minority whose advantages are entrenched. It is made even worse by gerrymandering, voter suppression, and campaign finance laws.
The Georgia runoffs are our best, very narrow, window to have some hope of improved democracy in the US. With two more Democratic Party senators that's a majority, and there's a much better chance of passing laws like HR1, to start bringing some more effective and fair democracy.
Without those Senators, gridlock is assured. 2 or more years of legislative inaction on Climate Change. That clock is ticking *very* loudly. Beyond policy issues, Mitch McConnell is already talking about vetoing Biden's cabinet choices.
If you're thinking that donating $10,600 to races in a "red" state is a folly that will come to nothing. Think again! Trump will not be on the ticket, and is undermining faith in elections and democracy with his own voters. This can depress Republican turnout.
Independent voters in Georgia can see that they have a choice between years of gridlock, or some limited but functioning government. That will change the electoral dynamics. There is every chance of returning two Democratic Senators in Georgia. The state just voted for Biden!
Let's have a working government. Today! Early money beats late money every time. If you're not a rich tech lottery winner, donate too of course, but if you are .... please max out! I know it hurts, but we owe this country a lot. A shot at a functioning government isn't nothing.
Gateway Load Balancer is *HUGE* and brings a capability to the cloud that has never even existed in traditional/legacy datacenter networks. It's not "just" ECMP. Flows are symmetrical, and sticky! Let me explain ...
GWLB let's you spread incoming or outgoing traffic over multiple firewalls, intrusion detection devices, packet inspectors, etc. It's horizontal scaling for network appliances, running on EC2 Instances. So far so good ... that sounds like ECMP.
But ECMP in datacenter networks doesn't align "north-south" and "south-north" traffic for the same flows (network connections) over the same devices, and it also "scrambles" all of the traffic when you add or remove a node to do any scaling.
Friday morning tweet thread: some more depth and detail on AWS Nitro Enclaves, the trusted execution environment / confidential computing platform which we launched last week. aws.amazon.com/ec2/nitro/nitr… . Let's dive in!
If you're reading this thread, you're almost certain familiar with Amazon EC2. The basics: EC2 customers can launch Instances, which are virtual servers in the cloud. "Virtual" means we make one physical machine seem like many machines. It's powered by our virtual machine tech.
With AWS Nitro Enclaves you get to also create and run more super highly isolated virtual servers that are attached directly and only to your EC2 instance. Think of it like having another server, but with no connectivity at all except a cable plugged in to your Instance.
Monday morning mini-thread. I rarely re-read books, but there are essays, letters, and speeches I re-read every year or two. Here I'm going to share 11 that have an enduring impact on me. Each is great writing, but also brilliant thinking.
1. The Inner Ring by CS Lewis lewissociety.org/innerring/. I'm not a big CS Lewis fan, but in this speech he condensed so much about how the world really works, and how corruption arises, and how to resist it.
IR gets across how the real movers and shakers aren't always the people with the titles or positions, and it distills a kind of soulful plaintive craft-like dedication to purity and quality that draws influence from religion and philosophy and shows up later in Pirsig's ZAMM.
@bhoflack@danluu We rejected a Maglev-like design because probabilistic LB doesn't work for the vast majority of workloads. Most customers have only 2 LB targets, they're also often slow, and subject to garbage-collection pauses. Probabilistic LB increases utilization way too much.
@bhoflack@danluu It's a design that works well when you have lots of very fast, very consistent targets. You could say it worked well at Google then, but I'm not sure I'd agree. It also imposes that constraint tax on your ecosystem; teams may be forced to optimize way earlier.
@bhoflack@danluu Our world view of load balancers is that they primarily an organizational tool designed to free teams from problems and complexity. Helps you not work as much on HA, GC, or long-tail latency, quite as much. The paper reads like awesome bin-packing is what LB is about.
The updated Apple | Google COVID-19 exposure notification cryptography paper is here: covid19-static.cdn-apple.com/applications/c… . Going to follow up with observations as I read it.
O.k. so first off; I've seen speculation that the change from HMAC to AES is to save power. I don't think this is true. The change to AES is to allow the phone to broadcast some encrypted data (the bluetooth power level) that can later be decrypted.
The power theory is silly IMO; Bluetooth IDs are only generated 144 times a day, the battery savings would be negligible.
1. If there is any layer that is actually between layer 4 (like TCP) and layer 7 (like HTTP or SMTP) ... *surely* it is TLS. But that's not a layer in the OSI model.
2. To double down on (1) ... have you *ever* seen layers 5 or 6 referred to? know what they are without looking? exactly? (also layers 5 and 6 make no real sense in a modern world).
