B-Con··on Google Employee Writes Memo About ‘The Burden of Being Black at Google’
Definitely some bias in reporting. If this happens at a small company no one cares, it's just another day.

Also I feel like Google had attracted some idealistic people who are surprised when real life doesn't conform to their expectations, then their reaction is disproportionate and overly centered on the work environment.

B-Con··on Nvidia CEO says Google is the only customer building its own silicon at scale
If you aren't auditing your dependencies, you don't know security. But we don't do that either, we outsource it.

This a reasonable thing to outsource: let someone qualified build their own.

B-Con··on Developers Who Use Spaces Make More Money Than Those Who Use Tabs (2017)
I suspect it could be large, well-paying companies with prescriptive style guides skewing the results. eg, Google standardized on spaces for all their languages I've interacted with, maybe some others did too.
B-Con··on Google Chrome Incognito Mode Can Still Be Detected
> All that is left to do is get in bed with the ad network to ask them if they have good cookies for this session.

What's funny is that this is pretty much what ReCaptcha v3 is. Asking how "authentic" the Google cookie looks.

B-Con··on Uber Posts $5.2B Loss and Slowest Ever Growth Rate
Calling is also archaic. Manually tell them my location and wait to hear a price? I'm on the go, I don't want to deal with that crap.
B-Con··on All the best engineering advice I stole from non-technical people
> But trust also degrades naturally over time. Italian researchers Cristiano Castelfranchi and Rino Falcone have a model of trust in which it’s observability not success that is the key factor. Under their theory an entity that is silently successful can end up seen as less trustworthy than an entity that visibly fails.

I would believe it.

From what I know, trust is a fickle, and irrational attribute. It places disproportionate value on first hand sensory input, and it isn't nearly a commutative as would seem reasonable.

B-Con··on Americans' plastic recycling is dumped in landfills
It's going to landfills for a reason. This has prompted people to investigate why and then write about it.
B-Con··on Some items from my “reliability list”
Pretty much this.

Writing code that can handle both old and new schema is admittedly annoying. But it's safe and forces a thoughtful rollout.

Even data mutations can be rolled back. Dual storage writes, snapshots, etc.

The goal isn't to eliminate risk, it's to reduce the risk and make it calculated and bounded. Heck, having a rollback plan that says "we'll restore a snapshot and lose X minutes worth of data mutations" is fine in some cases. It's tradeoffs.

(I've seen a case where literally adding a column caused an outage, because the presence of the column triggered a new code path. Rollback was to delete the column.)

B-Con··on Some items from my “reliability list”
I suspected.

Couldn't find a resume on her site to confirm it.

B-Con··on Some items from my “reliability list”
Required reading. Have you worked as an SRE?

> Item: Rollbacks need to be possible

This is the dirty secret to keeping life as an SRE unexciting. If you can't roll it back, re-engineer it with the dev team until you can. When there's no alternative, you find one anyway.

(When you really and truly cross-my-heart-and-hope-to-die can't re-engineer around it fully, isolate the the non-rollbackable pieces, break them into small pieces, and deploy them in isolation. That way if you're going to break something, you break as little as possible and you know exactly where the problem is.)

Try having a postmortem, even informal, for every rollback. If you were confident enough to push to prod, but didn't work, figure out why that happened and what you can do to avoid it next time.

> Item: New states (enums) need to be forward compatible

Our internal Protobuf style guides strongly encourage this. In face, some of the most backward-compatible-breaking features of protobuf v2 were changed for v3.

> Item: more than one person should be able to ship a given binary.

Easy to take this one for granted when it's true, but it 100% needs to be true. Also includes:

* ACLs need to be wide enough that multiple people can perform every canonical step.

* Release logic/scripts needs to be accessible. That includes "that one" script "that guy" runs during the push that "is kind of a hack, I'll fix it later". Check. It. In. Anyway.

* Release process needs to be understood by multiple people. Doesn't matter if they can perform the release if they don't know how to do it.

> Item: if one of our systems emits something, and another one of our systems can't consume it, that's an error, even if the consumer is running on someone's cell phone far far away.

Easy first step is to monitor 4xx response codes (or some RPC equivalent). I've rolled back releases because of an uptick in 4xxs. Even better is to get feedback from the clients. Having a client->server logging endpoint is one option.

And if a release broke a client, rollback and see the first point. Postmortem should include why it wasn't caught in smoke/integration testing.

B-Con··on YouTube videos that have almost zero previous views
Brings back memories of the Hare Hare Yukai craze.
B-Con··on So you think you know C? (2016)
Don't forget to include whoever reviewed it.
B-Con··on “The books will stop working.”
Yep. This is why I don't have a cloud-based digital library. UV offered a way to migrate to other providers, but will the next one? I don't know that they're legally allowed to. What if the other provider doesn't have the content, am I SOL?

I so badly wish I could buy a license to get a specific piece of content, get a copy to play on my own computer, then also have the ability to "upload" (aka, unlock) that content on a cloud streaming service of my choice.

B-Con··on ‘Dark patterns’ are steering many internet users into making bad decisions
But it reduces information overload! Improved UX!

I've made so many mistakes because I couldn't tell something overflowed. The scrollbar doesn't have to be big and ugly but it should still be present. At a minimum give a visual indicator that there's more content and then I know to try scrolling to see if it works.

It's a stupid UX fad.

B-Con··on How Virginia Won Amazon's HQ2
Wearing earplugs regularly isn't a solution, it's a sound bite and you know it. Just say you think peace doesn't actually matter.
B-Con··on Android now forces apps to include proprietary code for push notifications
They literally said that cell networks don't allow it without the keep alive. You quoted it and said they were wrong because... you can use a keep alive. I'm confused as to what you're correcting.
B-Con··on Living on the wrong side of a time zone can be hazardous to your health
Absolutely. I'd pick DST just to avoid this alone.
B-Con··on Living on the wrong side of a time zone can be hazardous to your health
Completely depends. Different people have different preferences. Different locations have different weather benefits for time of day. When I played golf I played during twilight almost exclusively.
B-Con··on What does it mean when a product is “Amazon’s Choice”?
Also stale inventory they want to move.
B-Con··on Protect Gmail messages with confidential mode
That's close enough, in big company dynamics being in an unrelated arm can be farther away than some members of the public. Feels like a nit.

I didn't imply every skeptic was donning tinfoil, but I saw a couple claims here and elsewhere in that range.

The default setting is to allow e-mails to be sent confidentially, not to actually send them confidentially. Seems like a typical default. Here's a new feature, by default you're allowed to use it unless domain admins want to disable it.

B-Con··on Protect Gmail messages with confidential mode
Edit: Removed my original write-up to double-check something, lost the write-up, retyped a tl;dr version.

This is aimed at Enterprise, not individuals looking for a Signal-like messaging platform.

"Confidential" e-mail implementations already exist in many places. Plenty of messages need to be e-mailed but the contents can't be inlined due to compliance. eg, medical systems send e-mail updates that are just a plain message but the e-mail is just a link to an auth portal and behind that is the actual message. Not great user experience.

But here, is G-Mail already has Google-grade auth and the same auth as Google Vault, so the document can be stored in Vault and in the e-mail the link and payload itself can be automatically swapped when sending or receiving. Smother user experience. eg, vertical product integration.

This is clearly targeted at Enterprise (G Suite, plus half the questions are about compliance). By default, Apps users are able to use this feature, although it can be disabled at the domain level by admins. It is not the actual sending of e-mails in this manner that's the default.

Put another way: If you don't see the point of the feature, you aren't the target audience. It's not trying to be Signal.

I just don't smell anything nefarious here.

Disclaimer: Am Googler, but unrelated to the project. Just heard about it now and have enough experience in this area that the feature's context seemed clear to me.

B-Con··on Self-distancing can help you make better decisions
This is me. I have a track record of making good, rational decisions that I end up regretting because it wasn't what I actually wanted. recently I've been trying to do a better job of checking in on my feelings to ensure present me don't make logical decisions future me will be aggrevated to follow up on.
B-Con··on Apple removes game after Chinese company cloned, trademarked, requested takedown
I'm confused as to why the takedown is worldwide. Does China threaten the company if they don't apply Chinese IP law apply outside of the country? Since their IP laws are terribly primitive they clash with the rest of the world, so that seems impossible.
B-Con··on Gmail really wants me to say yes
It is good enough, 2019 doesn't mean we don't reflect user behavior.

Not every recommender is a moral agent. Auto-suggest and conspiracy videos aren't the same thing.

And technically, yes, there's not such thing as a non-editorialized recommender, but this feels like a pointless nit since there's a world of difference between trying to be a reflection vs intentionally not reflecting based on a human-made moral judgement.

What even is the moral editorialization in auto-suggest? It's obvious we don't want conspiracy videos pushed front and center of educational topics, but how on earth do you balance the number of "yes" vs "no"? That's clearly going to be a completely made up number. If you don't have a clear problem to fight, it's probably best to not editorialize just to say you did.

B-Con··on Go is Google's language, not ours
This is the general point though. Community pressure would have produced generics under a different leadership model that wants to check the box.

Whether this is the right decision for this specific issue is a different story. But the fact that they aren't checking boxes for the sake of it is evidence of this style WAI.

B-Con··on Millennials and Gen Z Increasingly Pessimistic About Their Lives, Survey Finds
It's not pedantically incorrect, it's simply incorrect as well as partially misleading. It's an 11% occurrence rate now in a system that was designed to have this kind of feature.
B-Con··on Millennials and Gen Z Increasingly Pessimistic About Their Lives, Survey Finds
> Twice in the last 20 years - more than any other time in US history combined - The Presidential election went to the candidate that LOST the popular vote; These generations just lack a proper understanding of civics!

An untrue claim[0] that's been copy-pasted for a while. It has happened twice recently and three times before that, stop making it sound like it's unprecedented. None happened in the 1900s, so it's very rare (well, an 11% occurrence rate now) but not more than in the rest of history.

B-Con··on Bluetooth's Complexity Has Become a Security Risk
And they wonder why there's resistance to phones that are wireless only.

Their wireless audio protocol is bad and they should feel bad.

B-Con··on Treat Facebook Like Big Tobacco
> You can quit. We can quit.

> Sometimes I run into a group that I want to be more involved with that organizes on Facebook. When I mention I want to be involved but am not on Facebook, there is usually sympathy and a response that there are others interested in the group which are not on Facebook, either. Many organizations are multi-platform to be inclusive, and more organizations if more people spoke up to request a non-Facebook option.

I have not found this to be the case for casual (eg, meetup of strangers) or small (< 20) groups. They pick one coordination method and it's take it or leave it. Non-FB solutions have a strong drawback of some sort (lack of adoption, complexity of use, etc). Facebook groups and events are just super easy to set up and blast out.

I've been unable to avoid FB's groups and messaging. Adoption is just too high and so many people just can't be bothered to use something else.

B-Con··on California bill to add more housing in single-family neighborhoods blocked
Also because they exist. People who would move to CA but don't because of the housing problem can't vote to fix the issue.
