That sounds pretty expensive. With dapper the trace span annotations do nothing if the request isn’t being traced. If it is being traced you might have significant costs, along the lines of sprintf(“%.03f”, ...) or other very cpu-intensive activity. This is OK when you trace one per million but when you trace everything you have to think about the cost. This could lead to either just using more CPU than you really wanted, or to discourage trace annotations. Either would be bad.

Another nice thing about pull is you only pull from the authoritative source. If you have a daemon that has gone rogue your load balancer or naming system can throw it out of the named group/job/whatever even if it can’t shut it off. With push you might have zombies pushing duplicate data for what should be a unique target.

Not really. I just think it’s funny to see it described by one groups as a reasonable or even state-of-the-art system, while another group describes it as brain damage from ten years ago.

Prometheus is an escaped implementation of Google’s borgmon, which is seen inside Google as a kind of horror show, and alternatives have been developed. It is kind of frightening that it has got out in the wild and people like it.

There are also legitimate issues being brought up in other political posts but they have been banned anyway.

I wish threads about this clown would get disappeared down the HN memory hole the same way threads about Trump get handled.

Considering that address and date of birth strongly predict most of the digits of the SSN, this is pretty bad. Consider further than even name can predict SSN (people named Stein more likely to have been born at the Jewish hospital, and SSNs are sharded by hospital).

SSN is not a secret. End of story.

I'll give you one thing: the assets of the company are pledged to the senior bond holders, but then after the bonds are sold the PE company generally disposes of the assets, leaving nothing backing the senior debt.

The junior debt, of course, has nothing pledged to back it at all. Junior debt in leveraged buyouts is pure gambling.

My neighborhood Nextdoor is full of NIMBY on this topic. Apparently electrosensitivity afflicts some 90-95% of people who have the free time to go to city council meetings at 3pm on weekdays. Shungite pendants have been recommended to fend off the illnesses caused by radiation. Even the local school does not have wifi because some local bozo said his kids were "injured" by EM fields, not just any fields but specifically ISM wavelengths that are tuned to disrupt our precious cells.

I'd be frankly surprised if urban America ever gets 5G service while this kind of ignorance holds sway.

May I suggest compiling software? For people without access to distributed build and test a box like this is really nice. I do have access to a huge distributed build farm but even then I use a beefy HP workstation because the software that drives the build farm is itself a bit of a pig, and massively multithreaded.

I agree that minimum wages need not be uniform over large geographical areas.

Restaurant profits are controlled by landlords. The rent goes up just to the point where the business survives. Due to the natural shortage of space, this works perfectly for landlords and not very well for anyone else.

What the minimum wage does is create an unmoveable barrier that can't be negotiated away. Minimum wage lowers the maximum rent the landlord can charge without killings the tenant. The wages come out of the landlord's pocket, not the business's.

Technically the branch prediction benefit comes from partitioning the array around the critical value 128. Sorting is not necessary. Partitioning may be faster.

These ladies are behind the times. Gender politics at Google are now so advanced that feminism isn't even a thing. The "non-binary" and "genderqueer" have thrown the feminists under the bus. Frankly I'm shocked that the informal voluntary salary survey had the bad taste to try to classify gender.

Yeah, my taxes always just summarize capital gains as "various" on Sched. D.

I think their point was that it seems unfair to count up all the of the embodied energy of an electric car's batteries, but to only count the potential energy of the ICE car's fuel.

9 anni fadiscuss

True. However, while it is possible to make any kind of car with 100% renewable embodied energy, it is quite impossible to operate an ICE car on renewable.

That requires you to assume a certain mix of energy used to manufacture the thing.

We have that breakdown in California statistics and 91% of transport is private cars. Trains, planes, trucks, and off-road equipment is tiny.

I don't know about globally, but in California the carbon emissions from light vehicles are the largest component of the emissions inventory, and the only component that is growing. If entire fleet was electrified and entire grid converted to renewable, that would knock ~25% off emissions.
