davidf18··on New York’s Subways Are Not Just Delayed, Some Trains Don’t Run at All
Actually, in much of the system there is a great deal of redundancy so one track can be shut down for maintenance using weekends and 10 PM to 5 AM. For example there are often parallel local and express tracks (6 local, 4,5, express or 1 local and 2, 3 express or C local and A express).

Also entire train lines frequently run in parallel a few blocks from each other.

See: http://web.mta.info/maps/submap.html

davidf18··on Why Can’t Americans Get a Raise?
By far the greatest part of Trump's wealth comes from the "rent-seeking" that I mentioned. The sources are all political: 1) zoning density restrictions, 2) overregulation (e.g. in a city with mass transit and Uber, parking spaces, and lots of red tape to increase time of construction) and 3) overuse of historic landmark status. This rent-seeking is all implemented by cities run by Democrats.

Thus, it is Democrats who are most responsible for making Trump far, far wealthier than he would be without their assistance. This while adding to inequality and making rents for even small apartments very expensive.

Incidentally, in Japan in 2001 or so they passed a federal law which overruled local zoning density restrictions. The result is that in 2014 140,000 housing units were built in Tokyo compared with less than 90,000 for all of California and 20,000 for NYC.

The author has a degree in history. Perhaps it would be helpful to have an economist write an article about economics. I am not one, but at least have training in jobs that require analysis and not dogma.

1. Wages are just part of the overall benefit package per worker. Healthcare costs to firms have been rising dramatically and these higher healthcare costs (even as employers are having workers pay more out-of-pocket) have resulted in a flat overall wage payout.

2. What should be focused on is overall standard of living and not wages. In cities such as my own, NYC, but also SF, LA, SD, Boston, DC, the price of housing and commercial real estate (an increasing cost to businesses which can result in lower wages paid out) is caused because of "rent-seeking" that causes an artificial scarcity of land through politics that limit zoning density with the resultant higher proportion of income going towards housing costs. The rent-seeking benefits special interests which in this case are wealthy landlords such as Donald Trump.

3. Importing illegal immigrants holds down wage costs among the working class. Except for Trump, almost all Democratic and Republican Presidential candidates wanted to import illegal immigrants.

4. Exporting factory jobs to China and Mexico have also kept wage rates low.

5. The abuse of H1-B Visas have helped to keep wages lower among STEM workers. H1-B Visas are supposed to be used only in the case where there is no American with the skill set to fill the job. Many Democrats and some Republicans actually want to increase the number of H1-B Visas to further depress STEM wages. Trump campaigned against H1-B Visa abuse and spoke against Disney replacing 250 American IT workers with H1-B from India, a clear abuse of H1-B. Clinton did not speak out against H1-B Visa abuse.

6. Raising minimum wage by law to $15 per hour as the author suggested demonstrates to me that he wants to take this simplistic solution which ends up with higher costs to poor people who have to buy goods and services.

In summary, instead of focusing on wages alone, focus on standard of living much of which is poor because of rent-seeking which benefits wealthy landlords to the cost of everyone else. When focusing on wages, deal with the structural issues which are 1) increasing costs of healthcare and other benefits 2) increasing real-estate costs to businesses, 3) eliminating illegal immigrants 4) eliminating H1-B Visa abuse and decreasing the number of H1-B Visas.

Raising the minimum wage through law simply lowers the standard of living to the poor such as retirees on fixed incomes as the grocery store costs and other costs increase.

Like any other form of capital equipment, robots have other costs besides initial purchase and electricity such as maintenance and reprogramming.

Various forms of farm machinery such as combines automated farm jobs for the better. So true with robots in factories and artificial intelligence that replaces lawyers for standard contracts.

davidf18··on Architect explains why large development in LA seems to be luxury development
There are just a few major metro areas in the US where much of the rent-seeking for wealthy landlords is much of a problem starting with SF, LA, SD, Boston, NYC, DC. Not all cities bow to the wishes of wealthy landlords by making land scarce through artificial political means with the resulting huge financial windfall for wealthy landlords at cost to renters and millennials trying to buy a home.

> "Well, the Pentium M was just a refreshed PIII"

I respectfully disagree. These are direct quotes from the Wikipedia article mentioned above. The Pentium M (Banias) was an innovation of increasing the (maximum) speed vs. power ratio. Intel chose not to extend to x64 because they wanted to market an entirely different 64-bit architecture, the Itanium processors.

I am very pleased that AMD came out with it and forced Intel to do the same, but the Pentium M was (for microprocessors) a true innovation.

"The Pentium M coupled the execution core of the Pentium III with a Pentium 4 compatible bus interface, an improved instruction decoding/issuing front end, improved branch prediction, SSE2 support, and a much larger cache. The usually power-hungry secondary cache uses an access method which only switches on the portion being accessed..."

"Other power saving methods include dynamically variable clock frequency and core voltage, allowing the Pentium M to throttle clock speed when the system is idle in order to conserve energy, using the SpeedStep 3 technology (which has more sleep stages than previous versions of SpeedStep)..."

"...Pentium M varies from 5 watts when idle to 27 watts at full load..."

> "The processes for fabrication was surely because they maintained their monopoly and having money to buy the best tech rather than innovation."

My first job was VLSI designer (GPUs) and I follow the industry. Intel is the innovator when it comes to fab. IBM has a fab (or just sold it) in Upstate NY, but they could not keep up with Intel.

The Pentium M (Banias was the first processor) was developed in the Haifa, Israel design center and it is the first example (in microprocessors) of slowing the clock rate and performing more computation per clock cycle. This was released in March, 2003. Could you please cite examples of competitors releasing low TDP models before this?

While it might be ideal to have local control, cities such as my city of NYC respond to special interests -- in this case wealthy landlords. The local government serves wealthy landlords by making land artificially scarce and scarcity is reflected in higher prices. In microeconomics this is called "rent-seeking" which in this case is using politics to create profits far, far higher than costs. Thus Donald Trump and other wealthier landlords are getting huge sums of money from renters who are paying far, far more than they would in an efficient market. By responding to the campaign donations of wealthy landlords the local city councils have created a regressive tax and this is also a major form of inequality.

The local city councils respond to lobbying on the part of wealthy landlords by 1) zoning density restrictions, 2) overregulation and amount of red tape needed for approvals, and 3) overuse of historic landmark status.

Harvard Economist Edward Glaeser has written extensively about these problems. For example: Build Big Bill http://www.nydailynews.com/opinion/build-big-bill-article-1....

See also: 40 Percent of the Buildings in Manhattan Could Not Be Built Today https://www.nytimes.com/interactive/2016/05/19/upshot/forty-...

The solution is to use the one in used by Japan which is to have the federal government override the "rent-seeking" local city councils. The honest truth is that these city councils make renters and younger people pay far, far more for housing while giving Donald Trump and his fellow wealthy landlords far, far more money than their costs.

But Intel did innovate: The processes for fabrication are ahead of all others.

Also, they were the first to move away from the "higher frequency is better" to running lower power CPUs with more computation per clock cycle for mobile.

IMHO, Apple should have moved to Intel when the IBM PC came out. The IBM PC used the Intel 8088 which ran Intel 8086 16-bit processor while using a cheaper 8-bit bus which could use the more mature and less expensive 8085 interface chips. The Apple II had only an 8-bit processor.

davidf18··on Why I deleted my Facebook account
When I first starting FB, as one of the very first schools as part for the site, it worked really well. Now for some reason there are bugs that allow info I don't want not from my friends. I can't figure out how to turn the junk off. Does anyone know how? All I want is info from my FB friends.

I've stopped using it because of all of this junk.

They took something that worked well and made it not work well. Brilliant.

davidf18··on Why Tesla Is Worth More Than GM
I believe that much of the difference between Comcast and GM are because of number of customers who are revenue generators and the barriers to competition that Comcast would have compared with GM. While there might be many loyal GM purchasers, (I don't know that metric), Comcast does have competition for cable TV (e.g., many who are "cutting the cord") but not so much as an Internet provider, AFAIK.

GM's high revenue/profit vehicles require a lot of gas compared with the lower revenue/profit vehicles and thus the projected cost of gasoline probably is part of the GM valuation. For now, and for the future, thanks to fracking and (relatively) low demand from China, it appears as if GM should be having increased profits.

Regarding, Tesla's valuation, there must be some metric for customer acquisition.

davidf18··on New Skype Update Is Horrible
Well, you can also use FaceTime with iPads.

In the US, many people have the iPhones and iPads. For professionals worldwide at least in developed countries, it makes sense to use iPhones which are far, far more secure than Android platforms, especially when taking into account total cost of ownership, the monthly fee for cell service on a high quality network.

In professional settings, the Mac is becoming a more popular platform, IBM is converting many Thinkpads over to Macs.

Many in Europe, even the young, smoke cigarettes which are very costly with the taxes. I'd suggest for both health reasons and using money for better purposes to quit smoking cigarettes and use the money for iPhones (and Macs).

A pack of Marlboros in Germany is about $8 per pack according to Wikipedia.

My daily cost for being on the Verizon (top cell provider, esp in NYC) network and having Verizon yearly upgrade for latest iPhone is $5 per day. Upgrading to latest MacBook 15" Pro from recent model is about $2 to $3 per day.

The Macs, iPhones, and iPads play much better together as an ecosystem.

davidf18··on New Skype Update Is Horrible
Use FaceTime when you can. A lot of people have iPhones and many these days now have Macs.
davidf18··on Science Won’t Save Vaccines from Lawsuits Anymore
"This week, the highest court of the European Union handed opponents of basic public health their greatest legal victory in recent memory. At a time when a widening measles outbreaks across Europe and a growing pattern of parents refusing to immunize children, the Court of Justice of the European Union — the rough equivalent of the U.S. Supreme Court — decided that courts across the Continent may weigh whether a vaccine caused an illness regardless of whether or not there is any scientific evidence linking the two."

Well, at least thanks to BrExit, you can still have public health in England.

I live in NYC and I see people smoking cigarettes which cost about $12-$14 per pack. Some people smoke 1 pack a day and some 2 packs a day.
davidf18··on O'Reilly's Decision and Its DRM Implication
I liked using the O'Reilly early release program available from the site (as well as Manning's MEAP program). Is there any replacement for that now?

I also prefer the PDF versions which I can print out a chapter when I need to read hard-copy Instead of carrying with me an entire book (live/work in Manhattan, we don't use cars much and value light-weight equipment).

davidf18··on The history of the IBM PC, part one: The deal of the century
The IBM PC used the 8088 CPU which offered the same 16-bit execution unit of the 8086 (and thus superior to the 8-bit Apple II) while using only an 8-bit bus which was the same size bus as the Apple II. The 8-bit bus of the 8088 was compatible with the more mature 8085 thus allowing the IBM PC to use more proven, cheaper parts. The 8088 part itself was cheaper than the 8086.

In my view, this was a brilliant design choice and a pity that Apple didn't do the same.

The 8088 was designed in the Haifa Israeli Design Center.

Look, just read the article and you'll see it:

"After several months, he had recovered enough to be discharged. But, out in the world, his life was simply another hospitalization waiting to happen."

Hospitalizations can cost thousands of dollar per day. So this stay cost in the several hundred thousand dollar range.

[skipping some paragraphs]. He is given a stable housing environment:

"I spoke to Hendricks recently. He has gone without alcohol for a year, cocaine for two years, and smoking for three years. He lives with his girlfriend in a safer neighborhood, goes to church, and weathers family crises. He cooks his own meals now. His diabetes and congestive heart failure are under much better control. He’s lost two hundred and twenty pounds, which means, among other things, that if he falls he can pick himself up, rather than having to call for an ambulance."

The entire article is about this sort of thing and about many cases.

He Is perhaps the most famous real estate developer worth billions with a lot of holdings in Manhattan. While a lot of Democrats claim to hate him, they are usually the ones on city council that pass these rent-seeking laws that are a regressive tax that gives Trump huge sums of money at the expense of working people.

It us known in medical circles that take care of the poor. I am speaking of people that cost the medical system a huge amount of money. This is a great explanation.

In NYC and not only Manhattan housing is expensive. Yet in NYC is where a lot of jobs are. Taking care of very poor populations who may indeed have very high medical costs are substantially reduced by giving them stable housing which is hard to do with zoning density restrictions that makes housing expensive.

It is a regressive "tax" and it creates more greenhouse gas since people have to commute farther, and it contributes to income inequality. It enables special interests to take a share of wealth without creating it through innovation by created by others through innovation.

These four items are deemed by society as wrong or bad and therefore it "wrong" as you say.

davidf18··on Despite money and effort, homelessness in SF as bad as ever
The issue is that special interests have a much more focused need for the laws (or may have more money for lobbying or "buying" politicians).

There are import tariffs on sugar that benefits sugar producers while "harming" society (and other countries that want to import sugar).

https://en.wikipedia.org/wiki/Rent-seeking

Pick up a microeconomics book and it will explain. In microeconomics market inefficiencies or market failures have 3 causes: 1) rent-seeking, 2) negative externalities, 3) information asymmetry.

As I explained somewhere else in this post, Economist David Ricardo first discussed this problem of rent-seeking about 200 years ago. In this case, the wealthy landlords work to pass laws that give them wealth paid for by society or in this case renters.

David Ricardo first discussed rent-seeking with the Corn Laws of Britain which had a tariff on all grains which increased the wealth of landowners at the cost of other members of society.

https://en.wikipedia.org/wiki/David_Ricardo#Protectionism

davidf18··on Despite money and effort, homelessness in SF as bad as ever
Scarcity results in rising prices. In general wealth creation comes from productivity. There are many in society including special interests that are not interested in creating wealth but taking it for themselves while harming society as a whole. That includes not only wealthy landlords but many other groups of people don't want competition.

Another example is limits on taxicab medallions (which we have in NYC) so that medallions in NYC were valued at $1.2 million each and higher fares for passengers but that scarcity was fixed by competition from Uber/Lyft so that now medallions are only worth $700,000 or less and fares are less expensive than they were.

Another example is labor unions. Various forms of tariffs also create scarcity benefiting the special interests over the needs of the general population. Many jobs have extraordinary educational or licensing requirements to create scarcity and limit competition.

When it comes to housing wealthy landlords want their land to appreciate so they lobby politicians to pass these regressive laws. Without spending a cent, simply reversing the artificial scarcity in housing means that renters pay less for rent and more for goods and services, the construction trades have jobs, etc.

Homelessness comes from high cost of housing. It is emotionally convenient to blame other causes, but there is still mental health support in cities through federally funded community health centers.
