There is with Virtual Machines. You pay for uptime, a reboot is often necessary to add more storage or memory successfully to an existing VM, and even for local development VM's they take significant server RAM for their active kernels. For many VM's, proper nightly backup snapshotting also requires a short shutdown. Also, after activation of new services, it's often useful to reboot the system to ensure complete activation of services when and if they *are* rebooted unattended.

Systemd has also taken over network configuration with an unnecessary DHCP service, which it should _not_ have touched, automounting, and is now attempting to manage user processes with misfeatures that kill user processes silently, such as the default enabled "KillUserProcess" command. Please be clear that systemd is not attempting to _manage_ processes. It is attempting to directly manage almost _all_ system services, many of them by direct replacement with dangerously incompatible and modified systems.

One change is that they tests became much more stringent, and more accurate. This lowered many reported fuel efficiencies considerably. have become more true as the fraud became more noticed. Another change is emissions standards, which can play havoc with fuel economy. Some older, lighter cars with no catalytic converters had notably better fuel economy than more recent cars of similar size and model. Another change is increased safety requirements: Crumple zones and air bags add mass, cost, drag and in some cases all three to vehicles.

> Now the way you get tell fakes from the genuine product is because they were made better and lasted longer than the genuine product

Generally, no. The fake sneakers tend to be made with poor quality vinylized fabric rather than leather, the soles are thin and wear out quickly, and the stitches are more sparse and seams done more with glue than with stronger stitching. And since they're fake, the chances of getting a refund from the manufacturer are very poor, much as they are with other goods.

The fake name brand problem also includes Cisco and other quite high end network equipment, cheap phones that have been "skinned" to look like iPhones, tools and toys made of poor quality tin instead of the expected steel, and children's toys painted and made with toxic levels of heavy metals. It's not merely a matter of defrauding trademarked vendors, but of selling dangerous objects to unsuspecting purchasers.

The H1B visa workers help foster profits for the top mangers of the companies that employ them. Donald Trump's policies are _all_ aimed at putting power and money in the hands of the wealthy. It should be trivial, as the president and with a Rep8ublican congress, to "reduce H1B visas" for his supporting voters but leave in large loopholes to protect their broad corporate use.

Electromechanically, it's apparent. In terms of feedback that can be read by any sensory circuitry on the PC itself, it is not. A headphone or speaker circuit need have no _sensors_ that can be read or recorded by the signal generator. I'm afraid it's the introduction of simple chip solutions, designed to connect different electrical jacks to different programmable signals, and the introduction of A/D circuitry for noise cancellation and microphones that allows the cross connection of what is normally an output circuit to an input circuit.

Such features help reduce costs of circuitry for computer motherboards by providing single well designed, well understood chips for both functions. But it's not a design requirement.

HFT relies heavily on the positive feedback loops it starts, and rides like a surfboard, to deal hundreds or thousands of incremental trades to a new price. The volume of trading _itself_ generates positive feedback.

> BTW, now that pretty much 100% of traders are on a "high frequency" platform now,

I'm afraid you're overstating its popularity. HFT peaked in roughly 2009, and has fallen to less than 50% of trading volume in the last few years. Revenue from it has also dropped profoundly in the last 5 years.

"Market Manipulation" is the basis of high frequency trading. I wasn't claiming that what Sarao was doing was, itself, high frequency trading.

Much of the profit in high frequency trading comes _precisely_ from providing small feedback loops, and cycling through them all the way to where the stock bottoms out or peaks, then riding those same cycles the other way as the stock returns from any over-response. And yes, the high-frequency generates small positive feedback loops that drive stocks more quickly towards their equilibrium, and sometimes beyond. Much of the subtlety of the management of HFT is to detect exactly where the inflection points are, and to avoid overstimulating the stocks to a level where the SEC will admit the problem and insist on effective delays to trading, delays which would drain HFT's advantage.

Illegal or not, it's the basis of high frequency trading. The instantaneous sales, _themselves_, cause direct feedback and tip the market in various directions, which the high frequency traders pre-analyze and step out at _precisely_ the moment to maximize their own profits. It's built into the system.

As an IT professional who handles confidential data, and data security, that act was not "cutting a few corners". The leaks show that she was using the private server for direct activity as the Secretary of State as a matter of course. I've helped fire people who were pulling such abuses, especially for sensitive data such as HIPAA protected medical documentation or FERPA protected educational records.

Like failing to scrub a computer for handing it over to another employee, or leaving your passphrases on sticky pads on your desk, it's a very foolish and normally unnecessary act. Please don't ignore the very real misbehavior revealed by these leaks and charges.

That said, the woman is _far_ less dangerous than Mr. Trump, whose insistence on gambling at every level of personal and professional life is legendary and constitutes a _much_ larger danger.

Because many intro CS majors learn actively dangerous practices which take years to unlearn. Excessive recursion, excessive object oriented programming, a blanket refusal to look below or above the designated layer of abstraction for the particular class assignment, code that does _not_ run correctly on even slightly different versions of Java due to hidden dependencies and the consistently hand-managed list of local libraries keeping production from matching productioni or test environments, and the deadly insistence on relying on out of band "garbage collection" to recover resources all burden Java and help prevent it from being a high performance or high reliability language.

I could go on with the foibles of CamelCaseForEverything programming and the dangers of compilation environments that randomly select the latest versions of all components from poorly maintained 3rd party repositories such as those used by Ant, Maven, and Gradle. But I suspect you've gotten the idea. Unlearning all those dangerous practices can take decades.

I'm afraid that former Secretary Clinton's party beliefs have been fairly clear, we saw them during her husband's administration. We also saw, with her email on a private server, that she's willing to ignore existing law, basic security practice, and a concern for setting safe precedents for IT in the name of political expediency.

I expect Mr. Trump to be _much worse_ because he's a political "big vision" leader, who squanders enormous resources on theater, and he is personally and professionally addicted to gambling with _enormous_ stakes in the name of his visions. That is not safe for IT, and it's not safe for handling surveillance policy, civil rights, or the enormous amounts of personal data accessible with or without warrants in the USA.
