Now, if you had a perfect simulation of fluid dynamics of mercury- you could use piezo-pumps and image correcting software to angle it partially and compose a image at a angle.

Actually- if you do know the fluid dynamics of mecury in openspace, and how to push it where you want it- you can do the same thing up there.

Screw my rotor idea, all you need is a way to influence quecksilber in space, push it and take a series of images - that is recomposed into one giant hiRes picture.

So, one needs a strong magnetic field to push the mercury into shape, a closed tube, able to withstand that magnetic force and a shielded camera. Or you spin the tube, while applying the magnetic force, thus getting the mercury to collect at the side. Also the mirror would be selfrepairing..

I really like OpenShift. I had a hard time grokking K8s but OpenShift is much more friendly. I was able to PoC a microservices app on OpenShift with Minishift[1]. This way you can play around with it locally and make sure you understand what you're doing. The documentation is pretty good. Red Hat has stepped up big time in this area.

The difference between an incorrect description of a paraglider launch and a nonsensical comparison regarding the amount of data Google stores is that the latter is intentionally being presented as a proxy for the potential impact of that data.

To be able to interpret the article in a useful way, it is important to be aware that a single long, high-res youtube video could be 5.5 Gb and therefore that figure doesn't imply anything about what google knows about you. Of course, it would be easy for a non-expert to mischaracterize an aircraft accident in a way that matters to a layperson's understanding of why the accident happened and who is responsible.

There are a lot of details that distinguish defined benefit pension plans. One is if the pension is promised by a federal government that can print money, so Sweden's pension would have to be compared to the US Federal government's pension.

https://www.aei.org/wp-content/uploads/2018/03/Automatic-Adj...

Sweden actually just made some great changes to their pension system, and in fact it's no longer a defined benefit plan in the traditional sense, so your benefit is not guaranteed (aka defined). Sweden went ahead and said we're not giving you any promises, and pension payments will be adjusted on an ongoing basis due to demographic and investment return changes.

On the other hand, you have state level and local governments in the United States that have traditional defined benefit pensions (you get at least $x based on this formula, frequently with a built in cost of living increase). Not only that, but some governments baked this into their constitution, so there's no way for these to be reduced. And state and local US governments can't print money, so they only have two options: cut costs and raise taxes.

On top of the above, there are perverse incentives for the people who set the pension benefits. Obviously, the union workers want the most they can get. The politicians need union votes to get elected (everyone in the union votes, but most Americans don't vote in local/state elections). So politicians can choose whichever actuary uses the most liberal assumptions to make the costs seem lower than they are, the unions vote for them, but of course the contributions to the pension fund to ensure these benefits is NOT required. So politicians can also choose to forego them, which they did and leave it for future generations.

Did you read the report? The problem is that PROMISED pension benefits have grown, there's no funding problem if the amount of promised benefits grew with the economy or with revenue.

Accountability. When someone sends false or misleading information through a broadcast medium like TV, they can be called out and corrected (up to and including criminal penalties). When each person receives their own unique messaging, there's no way to find out what lies might be spread and therefore there's no way for anyone to take corrective action.
Privacy concerns are good and should always be raised. But before panicking like anything remember who gave them the data in the first place.

A few years back I made a hobby project like this -- it scraped the website of the local free weekly paper (since they have pretty much every concert listing, large and small) and then did a youtube search on band names so you'd see an embedded video or two for each show.

I think most larger cities (and smaller cities if they have a large university) have such a newspaper (e.g. Village Voice in NYC, Willamette Week in PDX, The Mercury in Seattle, etc)
This (or the original, rather: http://www.wirepoints.com/illinois-state-pensions-overpromis...) is a lot of graphs and percentages with very few absolute numbers, and all of them deceptive, with endless spurious comparisons such as comparing the percentage rise in "promised pensions" to the rise in average income.

Literally inviting you to think that retired state workers make 11x the average salary of working people in Illinois. They do this by comparing the total pensions committed to be paid over a lifetime to people to a bunch of yearly metrics, and most deceptively of all, comparing the rise in total promised pension payments to the rise in inflation during the time that the promises were made.

The people who wrote this report are terrible people who were paid to sell a conclusion, not to study anything. The reason that everything was pushed to pensions was simply a way to pay employees less. If they simply paid their workers, they wouldn't have to promise such a luxurious retirement.
Oh yes, America only, at least as far as I am aware of. I should have specified that.

I tend to use 50 years as my rough "long term" definition. "Facebook won't be around in 50 years" is not very impressive. "Facebook won't be around in 2020" would be a bold prediction, but doesn't seem very "long term". "Facebook won't be around in 2025" might be starting to get into "long term", but is also definitely starting to feel vacuous if we think of it as "The probability of Facebook being around as a distinct entity in 2025"... well, no duh it's not going to be 100%, but the probabilities get fairly uninteresting quickly. 50/50 is a decent initial guess for that, and it isn't until you get into the 90s on either side that it starts becoming an interesting prediction.

I don't know how to turn "Facebook won't be around in the long term" into an interesting prediction without a time horizon.

Here's a non-vacuous sort of example: There's a proof somewhere that the maximal probability of the expected future lifetime of a given organization like a country or a company is its current lifespan, projected into the future. So the maximal probability of when Facebook will be gone if it is currently 14 years old is 2032. However, I can not seem to Google up the discussion of this; all the search terms I can come up with are flooded by actuarial discussions of human mortality where this most assuredly is not the case.

That is a good question; I will admit that for many people, online conversations are much more meaningful and comfortable than ones "in the flesh". But what I personally like about real conversations (as opposed to virtual) is essentially that you communicate a lot of things i.e. its both verbal and non-verbal. So I think real conversations make more sense to me in only that I understand another human being a lot better than if it were just text on a screen.

Also, real conversations can lead to real friendships and such; I've found that hard to do virtually.

Indeed, this sadly will not be scalable to certain cities where the data source is incomplete. The author had posted this on the Austin subreddit a few weeks ago and I asked him if the source of the data was Showlist Austin (http://showlistaustin.com/) and he/she confirmed that it was in fact at least one of the sources for the Austin data. It's great that we have that site for Austin but it's probably the only place I've ever been that has that complete of a list of good local shows.
To what extent is this, or will this be enforceable? Is there an obligation to securely erase data? If not, presumably someone could store user data on a log-structured file-system and disable garbage collection, or similar.

Having quickly read the paper, the deletion guarantees seem slightly weak.

An item's position in the table is derived from two things: a fingerprint (a constant-sized hash) and second hash (ranging over the table). Nothing prevents two or more items from colliding on both hashes and therefore being indistinguishable from each other.

If the number of items in such a collision exceeds twice the fixed bucket size then deletion may result in false negatives.

In most practical applications there will be no useful way to bound the number of collisions. The paper shows results with bucket sizes of 4 and 8, but I don't know what the real-world probabilities of breaching these limits would be.

Not true. You can use exactly the same techniques in C, C++ and Rust. It's called arena based allocation.

Even malloc calls can be very cheap. The Hoard allocator uses bump pointer allocation for malloc into empty pages!

> paying yourself exorbitant over-market compensation

It would be super-cool if the report was about this, but it's not. There's not a shred of evidence given that the compensation given to state workers was over-market.
When you "pay" workers with delayed benefits like pensions it doesn't break your budget, it becomes someone else's problem. Hence high, unfunded pensions with government jobs.

While we're on the topic of homebrew package managers, I think some people here might be interested in checking out Exodus [1] [2]. A lot of the project philosophy actually overlaps quite a bit with that of qpkg. Both projects seem to be focused on simplicity, produce tarballs which can be extracted anywhere and run on any Linux machine, and avoid collisions without a centralized database. Unlike qpkg, however, Exodus isn't concerned with compilation and does automatically handle dependencies. It does so by using the system linker to discover required libraries, and then creating small wrapper executables which invoke the linker with the necessary library paths.

I could actually see it being used in conjunction with a script like qpkg, where the script handles compilation and then invokes Exodus to produces self-contained bundles with all of the necessary dependencies. Exodus is generally agnostic to how software it bundles was initially installed or compiled, which has lead to some interesting use cases. For example, we've had a number of people use Docker images to install software from Debian or Alpine package repositories, and then use Exodus to repackage single applications to run in microcontainers.

Right, and even a cursory search would reveal that for license violations, you can file a DMCA takedown request with Github against the offending repository [0]. It literally takes ten minutes and Github is required by law to act immediately and ask questions later. And then at that point, the ball's in the other guy's court. He could file a DMCA Counter Notice with Github to get the repository reinstated, but in doing so, he is swearing under penalty of perjury that he is telling the truth claiming that he didn't violate the original code's license. If the forker didn't credit Wonder Unit as required by their original license [1], well, then clearly Wonder Unit has a case to have the code removed. This isn't Vietnam. There are rules.

My company is running it in production. We started with the monitoring stack and then our application, which is a SaaS product. The product itself is a stack deployed on a per customer basis. With rough configuration management using chef and terraform it took an ops person hours to complete a deployment a year ago. Today, it takes a minute and it's self-service for engineers.

Efficiency is increased a great deal. Previously, I'd have idle instances costing money when they were unused. Now my resource consumption is amortized across my entire infrastructure.

It also drives an architecture that lends itself to better availability. A pod in k8s may be rescheduled at any moment. If it's a stateless service, one may just increase the number of replicas to prevent a service interruption. If it's a stateful service, one is forced to think about how to persist data and gracefully resume operations.

It took a while for everyone on my team to get familiar with it, but once we started to really grok it, the sense of safety went way up. I feel pretty good about the fact that if someone accidentally blew away a cluster with thousands of pods in it, that I could easily replicate the entire thing and get it back up and running in tens of minutes without a lot of hassle.
Defining the benefit and failing to fund it is literally passing the buck.

Doesn't matter if the failure is intentional, luck, whatever.
Long story short, if you defer compensation you suffer a significant chance the other(larger) party will manage to screw you out of it.

The same is true if its a private or state entity. You either get money or assets in hand, or its effectively vapor. It also shows that working for the government may be stable, its certainly not good for pay.
A few types of filters support deletion (e.g. counting bloom filters and cuckoo filters). To my knowledge all of them require prior knowledge that an entry was successfully inserted. That is, if you guess at deleting an entry and are successful, then you'll ruin the filter by creating a false-negative case.

As for collisions, only a limited number of colliding entries can be inserted into a cuckoo - after which a subsequent insertion will knowingly fail. So say Alice and Bob hash out to the same values, and you've inserted 2 Alices and 1 Bob. When you delete one Alice, it doesn't matter which entry is removed - two entries still remain that hash to Alice and Bob.

Perhaps the nuance you mention is that the alternate bucket index for an entry is calculated only from the fingerprint, not from the entry data. This has the effect that even when multiple entries share fingerprints, any one can be removed. (Again, _only_ if the system requesting the delete positively knows that the entry was previously successfully inserted.) The other colliding entry will still be found on query and will generate a "maybe" response.
Running GitLab CI specifically is absolutely amazing on K8S... Thank you so much for your efforts.

Yeah, the resins before they’re cured are pretty gnarly.

But the filament based plastics are usually fine. There is some questions around melting ABS in a home environment. The volume of gasses released are almost certainly below danger levels, but there are viable and ‘safer’ alternatives in PLA and PETG that are easier to print offering better resolution at the cost of high temperature resistant (PETG is similar to the plastic used in water bottles).

Unless you live in a dry, desert climate I’d advise against ABS anyway.

>-> they find (and fix) more bugs

Where is the evidence that this happens? Do you have data (Open vs closed) showing more security bugs were found through developers, versus external sources?

>-> the system is more secure, because all bugs are found and fixed, instead of being kept inside the code and being sold on hacker forums and agency surveillance projects.

Why would a hacker fix a linux bug for free, but chose to sell a windows bug? That doesn't make sense to me.
So you are suggesting that we regulate the Internet and make people who spread 'lies' (or in other words things they might actually believe) liable for their actions?
