the_evacuator··on Jaeger – A Distributed Tracing System
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.
the_evacuator··on Monitoring Cloudflare's edge network with Prometheus
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.
the_evacuator··on Experian Site Can Give Anyone Your Credit Freeze PIN
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.

the_evacuator··on Toys ‘R’ Us Plans Bankruptcy Filing Amid Debt Struggle
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.

the_evacuator··on The Debate Over Neighborhood Zoning Could Hold Up Fast 5G Wireless for Years
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.

the_evacuator··on HP Updates Z8 Workstations: Up to 56 Cores, 3 TB RAM, 9 PCIe Slots, 1700W
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.
the_evacuator··on How the Minimum Wage Affects Restaurant Hygiene
I agree that minimum wages need not be uniform over large geographical areas.
the_evacuator··on How the Minimum Wage Affects Restaurant Hygiene
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.

the_evacuator··on Why is it faster to process a sorted array than an unsorted array? (2012)
Technically the branch prediction benefit comes from partitioning the array around the critical value 128. Sorting is not necessary. Partitioning may be faster.
the_evacuator··on Google Sued by 3 Female Ex-Employees Who Say It Pays Women Less Than Men
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.
the_evacuator··on Mercedes-Benz will electrify its entire car lineup by 2022
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.
the_evacuator··on Mercedes-Benz will electrify its entire car lineup by 2022
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.
the_evacuator··on Mercedes-Benz will electrify its entire car lineup by 2022
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.
the_evacuator··on Mercedes-Benz will electrify its entire car lineup by 2022
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.
the_evacuator··on Legal Marijuana Is Almost Here, If Only Pot Farmers Were on Board
I hear you. The thing about a national forest is there are already roads, and already the sounds of logging. These are working lands. We set aside wilderness areas without roads, that are not even welcoming to horses, for those seeking peace.

Enjoy your lands.

Search for "trespass grow" to find a lot of magazine articles and videos on the subject.

I may shake my head at clear-cutting and overgrazing but I'll say that I've never been chased off public land by a rancher nor fired upon by lumberjacks. The marijuana growers are ... unique.

the_evacuator··on Legal Marijuana Is Almost Here, If Only Pot Farmers Were on Board
Article doesn't really highlight the environmental hooliganism practiced by these guys. They rip up a meadow in a national forest, or on BLM land, and they irrigate like crazy people, eroding everything rapidly, and they drive up and down the mountainside in their giant pickups. When they are done they leave everything including their trash and their toilets. When ordinary people go motorcycling in these public lands the growers chase them, shoot at them, and set booby traps. The whole thing is a public menace.

I think with legalization should come some kind of harsh regime for these pirates. Ruining public lands should be a serious felony.

the_evacuator··on Category 5 Hurricane Irma Brings 180-MPH Winds to Bear on Caribbean Islands
I beg to differ. Exodus of ~1m people in about one day is frequently observed in Europe. It can't be done with cars, of course, because cars are not a means of mass transportation. It can be done easily with trains, though.

Example: Street Parade Zurich, attended by about a million people. Virtually all of those people arrive by train immediately before the event, and are gone the next day. Watching > 100k people pour out of a train station in less than an hour is really a spectacle. Remember that Zurich is not a huge city in the first place.

Example: Paris goes on holiday. All-but-literally everybody leaves Paris for summer holiday, pretty much simultaneously. You don't know what an urban evacuation means until you've witnessed this.
