The allegation is that KMnO₄ is undergoing a redox reaction with HCl to produce Cl₂ gas (which is a plausible redox reaction, given the half-reaction potentials).

But yeah, in practice you're going to disinfect with Cl₂ gas or NaClO. The water plant I worked at switched from Cl₂ to ClO¯ as primary disinfectant, and the operators were all for it. No more need to manually switch out Cl₂ tanks, no more Cl₂ venting issues (spilling NaClO is nowhere near as bad a Cl₂ leak). (The plant also used O₃ for bonus disinfection as well. The operators hated it at first, but now would throw a conniption fit were it broken).

That's pretty much the point, isn't it? If I need true multithreading, then I am forced to write an extension in C or offload the multithreading work to another process (such as RDBMS in your case). It would have been nice if true multithreading was possible in Python itself. It would immediately make Python more useful in a variety of scenarios where splitting the work into multiple processes is not optimal or more convoluted.

> weight gain does ultimately come down to "you are consuming more calories than you are expending"

That is incorrect, but it does help sell gym memerships.

Moreover, expending more calories via exercise typically leads to weight gain, according to emprirical studies (and anecdotal look around gym's elliptical machines next time you're in one) https://well.blogs.nytimes.com/2014/11/12/exercising-but-gai...

Fat accummulation (and disposal) are governed by insulin, whose production is triggered by sugars and other carbohydrates.

Confusingly, consuming a high-fat, low-protein and zero-carbohydrate diet will also lead to a severe decrease in calories (as it's pretty hard to overdose on olives, coconut oil or lardo), but it's nevertheless a correlation.

Not really the same thing. Insurers in a purely for-profit marketplace will always be incentivized to reject coverage for people with pre-existing conditions and drop coverage for people who become sick, because both groups are unprofitable to treat. The only way to avoid this is with strict regulations preventing insurers from doing what's in their own best interests at the expense of everyone else.

Is it possible to rewrite your points to be "achievement" oriented rather than "technically" oriented?

As an example, your best point is last on the list: "Optimized the website to serve pages from 5s down to less than 1s via Apache configuration and caching."

It should also be worded as such: "Increased page speed by 5x faster with optimization techniques".

Be a little more sparse on technical details, and more bold on your achievements. Assume the reader doesn't know or care about the technical details. All they want is to be persuaded that you get shit done.

Avoid redundant information like "Consulted with ownership to establish project scope and business needs." Like seriously? You talked to people and worked on a team? No shit. Embellish your achievements, you must sell yourself.

Also move your education to near the bottom, lead with experience first.
Ordinary scalar multiplication can itself be expressed recursively, e.g. (2734 * 5896). Break each number into two parts and the answer is (27 * 96 * 100) + (34 * 58 * 100) + (27 * 58 * 100 * 100) + (34 * 96).

Fine.

Now what is (27 * 96)?
(2 * 6 * 10) + (7 * 9 * 10) + (2 * 9 * 10 * 10) + (7 * 6).
etc.
[In real life you'd do this in binary and the multiplies by 10 become shifts.]

This is not usually the fastest way to do scalar multiplication, but it illustrates that:

1. Ordinary scalar multiplication is polynomial multiplication.

2. Polynomial multiplication is convolution.

3. And since we can [sometimes] speed up convolution by moving it to the Fourier domain, we can multiply numbers by taking their FFTs first, doing an elementwise multiplication, and then taking an inverse FFT. This actually pays off on very large numbers.

Multiplication is fun stuff.
It's an interesting experiment, not some sort of production recommendation.
For what it's worth, as recently as early 17th century England did not have coffee. If you grant that the difference in caffeine between coffee and tea is significant, then we can conclude that Western Europe must have received those benefits only by the 1650's - 1700's.

I have always wanted to buy a countertop water distiller for home use. Guess I found another reason to justify the purchase =)
Ancient (specifically Roman) civilizations had fantastic systems to transport water and even developed indoor plumbing. They didn't need to augment their water quality with wine. Wine was simply made ubiquitous due to their civilization determining that it should be enjoyed by everyone.

Of course there are stories of soldiers augmenting pond water with wine, but this could have been as much to make it more palatable as preventing oneself from getting sick.

Here's a paper that talks about Ancient thoughts on water: https://issuu.com/eajournal/docs/articulo_-_van_tillburg_-_d... Basically, humans have for a really freaking long time been able to determine whether water is basically more or less safe to drink, and have not really worried about it more than any other thing (and certainly not drank beer or wine because they feared for the quality of the water)
Regarding "exploitation", I suspect that it is because employment markets are inefficient and non-fungible (based on location and many, many other factors, including culture and reputation) and that if a company's metric is hiring talent at the 90th percentile, then they may more quickly hit a limit where their ability to fill 90th percentile job salaries strips their ability to access talent in non-majority groups.

Efforts to reduce imbalance (regardless of demographic) is necessary to overcome location bias, and the bigger the pool, the higher the tide for all boats.

If you're "labor", stop thinking that you're at war with other demographics.

> and fairly damning.

Are they?

From what I have seen the consensus is:

An overall small 3-6% wage gap after accounting for basic life choices.

Women under 30 + childless women significantly out-earning women with children + older women.

Women under 30 + childless women have almost no wage gap and in many industries are out-earning their male peers.

Life is rough for the bottom 50% of earners - male and female.

What exactly do you think the stats show?

> and the jobs that are heavily weighted towards women do not pay nearly as much.

Why are you talking about women like they are objects without agency?

My friends in game design work harder than I do and earn half what I earn.

They made a trade-off and work in a more interesting and rewarding job that pays less.

They certainly aren't oppressed and discriminated against.

Now this isn't really true at the bottom end of the scale. But it is for the middle class and up.
First of all, thanks for writing this, since I did find the technical details quite interesting. But I don't think this puts microcode rootkits beyond the reach of a state actor. It puts them beyond the reach of a normal criminal attacker, which is actually my point.

Scenario 1: Supply chain interdiction. You don't need to target the CPU only after it has been manufactured and put into whatever you want to hack, you can start way earlier, including at the factory.

Scenario 2: Getting the signing keys from hardware manufacturers, including Intel, seems quite feasible for state actors. You don't even need hacking (I assume Intel's keys are kept air-gapped) or relying on secret court orders, plain old spycraft would probably do the trick.

That said, my argument can be rephrased to consider the hard-drive controller or other peripheral firmware rootkits instead, if you prefer and care only about scenarios where the rootkit must be delivered over the network to a clean system without attacking the CPU manufacturer.

High level observations:

1. Business level constraints (time, human, fiscal and other resources, stakeholders) trump technical constraints every time. Identifying these should be step zero in any design process.

2. A business-level risk model assists with appropriate design with respect to both security and availability and should ultimately drive component selection.

3. Content seems very much focused on public IP services provided through multiple networked subsystems. While this is a very popular category of modern systems design, not all systems fall in to this category (eg. embedded), and even if they do many complex systems are internal, and public-facing interfaces are partly shielded/outsourced (Cloudflare, AWS, etc.).

4. Existing depth in areas such as database replication could perhaps be grouped in a generic fashion as examples of fault tolerance and failure / issue-mitigation strategies.

5. Asynchronicity and communication could be grouped together under architectural paradigms (eg. state, consistency and recovery models), since they tend to define at least subsystem-local architectural paradigms. (Ever tried restoring a huge RDBMS backup or performing a backup between major RDBMS versions where downtime is a concern? What about debugging interactions between numerous message queues, or disparate views of a shared database (eg. blockchain, split-capable orchestration systems) with supposed eventual consistency?)

6. Legal and regulatory considerations are often very powerful architectural concerns. In a multinational system with components owned by disparate legal entities in different jurisdictions, potential regulatory ingress (eg. halt/seize/shut down national operations) can become a significant consideration.

7. The new/greenfield systems design perspective is a valid and common one. However, equally commonly, established organizations' subsystems are (re-)designed/upgraded, and in this case system interfaces may be internal or otherwise highly distinct from public service design. Often these sorts of projects are harder because of downtime concerns, migration complexity and organizational/technical inertia.
The only sexist thing here is your support of a baseless claim.

If it's not baseless, presumably you have something to offer.

However, without evidence, you are most likely wrong. Does that wrongness amount to sexism? Hard to say; my inclination says yes since you're referring to shuffling hundreds of dimensions defining employment into "life choices". Yes, that is probably a factor; culture is a powerful force. But it's also probably not the only factor; there are likely myriad explanations. Are you blind to that, or just dismissive?

Caffeine (and other stimulants) have been traded by many civilizations over many millennia in different areas of the world, and have not always given rise to technological progress. In addition, progress in the methods of creating alcohol have often been a side-effect of growing civilizations, not a cause for them.

The article makes an argument that here we humans were, dumb and boring, and suddenly we decided to create a means to produce certain products, and then we created trade routes for these products, and then suddenly this caused civilization to flourish, as if the presence of civilization was not necessary for these things to happen to begin with. It's like saying "the horseless carriage developed America", as if America didn't exist before it was created, to say nothing of paved roads.

This is what I like about FP. As in math, you're expressing ideas about relationships that must always hold true, regardless of time.

You can control the input in that equation, but on the output the body is quick to go into calorie preservation state any time the balance goes negative. Lack of energy, irritability, mid-day fatigue, general weakness, mild headaches - the list goes on.

In an ideal world everyone runs marathons while sustaining themselves on water and celery sticks. In reality maintaining consistent caloric deficit while trying to remain a functional member of the society is challenging.

There's a big difference between "we are living in a surveillance state" and "we are on a slippery slope to a surveillance state". A huge obstacle in getting more of the populace to care is the fact that many people who do care (and especially those who write and talk most often about it) seem to think every millimeter of hyperbole and lies in the "right direction" furthers the cause. Ask the Democratic party how that strategy works out in the end.

Internet manifestos like yours or ones that end with "I can no longer proudly claim the West is free. We are living in a surveillance state." empirically don't do shit except help convince people on the sidelines that people who care about the formation of a surveillance state seem to be kind of paranoid.

Actually want to get people to care? Talk about very well substantiated examples that touch things most people are familiar with. It's not like Snowden failed to give us a wide selection. Even if COINTELPRO's soul sequel is in place, you're better off going with a soft sell that hits closer to home than a hard sell that fewer people will identify with.
How is 2017 Looking for OTAs
I suppose you can hand-wave the aggregate results away if you're comfortable with that 3-6% gap. But your argument basically amounts to "what matters to you doesn't matter to me, so I consider it insignificant".

I do consider 3-6% damning.

If you only compare women to other women, of course you won't see a wage gap; you can blame it all on the individual.

It's this willingness to value personal views of the world to minimize the facts that allows the gap to continue. Do you really think you can reason about systemic discrimination by looking at the individual? That's as ineffable as wondering why some people win the lotto; individuals are dominated by noise, and you only see the disparity in aggregate.

Why bother commenting if you don't care about the wage gap?
For many algorithms you'll have to build and maintain a stack manually if you use a loop. I once saw an old Fortran routine that expressed Quicksort this way.
