Artificial lemon flavours that you find in candy and cough syrup taste much more like “sweet lemon” than the typical lemon found in North America. It is sweet when eaten within the first minute or so and bland afterwards. It does not taste acidic at all.

Many tools used in chip design are controlled with Tcl. It provides a stable repl for these heavy, multi-threaded, efficient, C++ programs.

Qualcomm invents breakthrough technologies that transform how the world connects, computes and communicates
The CAD team is looking for software engineers to build the systems we use to optimize chips with billions of transistors.
If you like working on distributed systems in a high-performance computing environment, then please reach out.
A knowledge of VLSI and EDA is not strictly necessary. Strong quantitative skills and/or experience with probabilistic graphical models is an asset.
If you are interested or have any questions, please contact Paul Pereira at [email protected].

You may wish to check out the MIT Pantheon project which ranks people not just by page views, but also by the log of birth year and number of languages that their biography has been translated into. With that metric, knowing Aristotle would be much more valuable than knowing Justin Bieber, whose name is likely to decline in importance well within one lifetime, and is perhaps hardly known at all outside certain countries.

The distincion between creating value and hacking the economic system is interesting.
“Think of Alan Turing, whose genius provided the mathematics underlying the modern computer. Or of Einstein. Or of the discoverers of the laser (in which Charles Townes played a central role) or John Bardeen, Walter Brattain, and William Shockley, the inventors of transistors. Or of Watson and Crick, who unraveled the mysteries of DNA, upon which rests so much of modern medicine. None of them, who made such large contributions to our well-being, are among those most rewarded by our economic system.”

Yes, but they will link you to a mobile number and then require that you confirm your number on grounds that they cannot identify you from your login. Gmail did not have my number confirmed until I moved and they locked me out of my email, despite answering all security questions. Theory and practice can be very different.

OpenBSD is very good at suspend/resume, particularly for non-bleeding edge laptops that developers have had a chance to use. I've had better luck with suspend/resume on OpenBSD than on Linux. I recommend Thinkpad X/T series laptops and have also had success with older Asus Eee PCs.

You have framed this question in terms of your freedom to contract in order to restrict distribution. Although many think contractual freedom is paramount, that is not necessarily so. It may be bounded by other more basic legal principles. In your chips example, it may be bounded by property and competition law.
In property law, there is the concept of a restraint on alienation. In competition/anti-trust law, there is the concept of a post-sale restraint. The idea is simple: after you by the chips, they are yours and you can do with them what you want. Restricting resale also limits competition, which is bad for consumers. Whether this view trumps your freedom to contract is a legal question whose answer has varied over time.
Historically, such restraints were a problem for real property in England. An estate might have been held in "fee tail" to be passed on to heirs indefinitely. Society decided that land was not being effectively used in this way, so fee tails were broken by statute beginning in the 1800's. Your freedom to "devise by will" was limited in favor of the property right of alienation.
Software was traditionally sold to the end user, who could use or sell the product as he wished, subject to Copyright restrictions on making additional copies for distribution. Only recently did this property-like right erode in favour of the current norm where software is licensed under a plethora of contractual restrictions you may never have read (the EULA).

It should be noted that these predictions are not based on the lawyers' pleadings, but on the facts and law sections from the judges' decisions.[1]
There is definitely a possibility of bias in the characterization of the facts. The authors state that for their appellate court, the facts section is uncontested by the parties and derived from the lower court's findings. Even so, it is not clear whether the court's reversal rate is high or low. If low, it could be that the lower court's presentation of the facts was equally varnished.
With some judges, it is possible to predict the outcome of the case from the very first sentence laying out the facts and circumstances. In a famous dissenting judgement by Lord Denning, in which he attempts to save a cricket field, the judge begins as follows:[2]
In summertime village cricket is the delight of everyone.
Nearly every village has its own cricket field where the
young men play and the old men watch. In the village of
Lintz in County Durham they have their own ground, where
they have played these last 70 years. They tend it well.
The wicket area is well rolled and mown. The outfield is
kept short. It has a good club house for the players and
seats for the onlookers. The village team play there on
Saturdays and Sundays. They belong to a league, competing
with the neighbouring villages. On other evenings after
work they practise while the light lasts. Yet now after
these 70 years a judge of the High Court has ordered that
they must not play there any more.
I doubt that this textual approach would work for the more technical parts of the law. Many cases are in areas with very few preceding cases from which to train an n-gram based algorithm. While the author's approach worked for certain human rights cases, it would likely fail for cases turning on an obscure tax provision.

The mobility between quintiles is not particularly interesting; it is far too coarse a measure. The changes in inequality that we see in the US, Canada, and the UK affect the relative earning capacity of the bottom 90% vs. the top 10%, with the 90th percentile being an inflection point at our levels of inequality.
The relevant reduction in mobility would primarily be within the top 10% tail of the Pareto distribution for income, the dynamics of the bottom 90% are quite different -- although their absolute share vs. the top 10% has certainly declined.

Just like public utilities don't have a monopoly on the provision of power, because, hey, every home-owner can buy a diesel generator. With the level of substitution you are describing, you've made the word monopoly meaningless.
The regional broadcasters for the Olympics have a monopoly because of their economic power in setting the price for their good. Other than circumventing copyright or using a VPN, there is no competitor that will provide you with the Olympics for less money. Random youtube videos are not a substitute for watching an Olympics broadcast live.
