  9. Two sides to that on Oracle Challenges Pentagon's $10 Billion Cloud Computing Contract (theregister.co.uk) · · Score: 5, Interesting

    I suspect the benefit to splitting things up may be obvious enough that I don't need to state it. On the other hand, over the years I've put a lot of thought into why companies use these clouds, and particularly AWS.

    Years ago I developed a small private cloud using a lot of technology I designed and architected myself, with coding help from my employees and a contractor for the UI. It was mostly about storage, and some really nifty ways of managing virtual machines, but the main cost was storage. Multiple people asked me why we didn't use AWS for storage, so even after I had already looked into AWS I double checked a couple more times. What I found was that their storage was MUCH more expensive than some very solid, very flexible storage built from standard open source Linux storage components (cLVM, etc) and some 16-bay Supermicro chassis. AWS was super expensive for storage, and for virtual machines. So why are so many companies using them so much? Years later, I think I have a couple of answers.

    There are a few reasons, but one is the level of integration of advanced things like auto-scale groups. Even getting just a load balancer working PROPERLY and configuring a static cluster of web servers is tricky normally. More often than not, the server clusters I see people deploy aren't actually clusters at all. They are a screwed up hybrid of a true cluster and a bunch of independent mirrors, which breaks things. AWS gives you a solid cluster in a few clicks. You can the easily save your entire cluster setup to your git repo as a Cloud Formation template.

    The big clouds aren't the best way to get storage, they aren't the best way to run virtual machines, they aren't the best way to run databases. The magic is the integration - with a few clicks you have all the right DNS entries pointed to your new cluster of web servers, which talk to your DB cluster through the Lamda functions, all backed by the magic storage in a seamless way. With a beautiful API for programming it all. That's where the value is, how Amazon brings all these different things together seamlessly.

    Breaking your operations up across a bunch of cloud providers meana giving up this seamless integration, duplicating whole data centers to another physical location with a few clicks, and haing everything still work.

    If you're not going to take advantage of how everything is put together, you may as well save a few bucks and have a rack full of Supermicro gear on premises.

    What exactly are you proposing? Bring more small businesses to town by having proportionately greater incentives to move into your city? Should your city offer me a 10 year property tax deferral to get me to bring my three-person company to wherever you live? Do you think that would work to get me to move?

    We probably both see how ridiculous this conversation is:

    Fred: Trump shouldn't be recklessly tweeting whatever comes to his mind. What a US president says impact, in the US and around the world.

    Bob: That's the argument. However Obama shouldn't have claimed to unilaterally declare new laws, after he himself said it would be unconstitutional to do exactly what he ended up doing.

    What Fred said is right, and while Bob says something else that's true, it in no way changes that Fred made a true statement.

    I ran small businesses for many years. The tax and government related thing that would have helped my companies had to do with paperwork. I filled out quite a few tax forms showing that the company owed less than $10 for a particular tax. The government probably spent $20 of employee times processing the form and my $4 payment, so it was a waste of taxpayer resources and a waste of my time. What would help small businesses, and save the taxpayers money, would be to exempt them from the many taxes types of taxes designed for large companies, where preparing and processing the tax paperwork costs more than the tax due. I've literally had the state call me about a 17 cent tax bill. The state employee's time cost them more than the 17 cents they collected. A paid a yearly tax for owning my desk and chair, with paperwork I have to full out every year showing how much my desk is worth.

    Large investments, billions of dollars bring brought into the city, are aided by deferring the property tax untill later year, rather than having to pay those the same year they just spent billions on a new headquarters.

    It's not an either-or. How about both? How about the various governments, local, state, and federal, stop being a huge pain in the ass for small businesses AND encourage large businesses to invest in the community? Its very, very good for small businesses like gas stations, dry cleaners, and day cares when a company brings 50,000 high paying jobs to town. That's 50,000 customers with money to spend.

  11. The Washington, DC way of doing it on Cities' Offers For Amazon Base Are Secrets Even To Many City Leaders (nytimes.com) · · Score: 4, Insightful

    I understand where you are coming from.

    Like it or not, other cities WILL encourage investment and jobs by waiting on the property taxes, so unless YOUR city does the same, or is otherwise very attractive, your city won't get the 50,000 jobs. Fortunately, it ends up working out well most of the time, which is good because there is no way to make it illegal. Congress shows us why.

    Congress of course passes thousands of pages of tax law. Taxes vary based on hundreds, if not thousands, of factors. The government can of course set different tax rebates and such for base load power plants than for companies who talk about one day making solar panels. Without a Constitutional amendment, it's legal to say solar power companies get a 250% tax credit. Unwise maybe, but perfectly legal. They can institute a tax on building new buildings, or a tax credit for building new facilities. Perhaps building a new factory over 100,000 square feet gets you a $500,000 tax credit.

    Following that line of thought, if they can give solar panel companies a negative tax, and they can hand out a tax credit for new construction, they can of course write a tax credit for "solar panel companies who build new factories" (no actual production of solar panels required).

    One could intelligently argue that it should be a flat, equal tax for everyone. That would mean deleting 99.99% of the tax code. One could also intelligently argue that the government may make the tax laws arbitrarily complex. What doesn't make sense is to say "it should be illegal for them to write various different rules, for different situations, except for all the ones I like. It should be legal to give billions to companies who have "green" or "solar" in their name, but illegal to allow natural gas companies to deduct their expenses just like every other business in the country". Make sense? Either they can make complex tax law, favoring some groups, or they can't.

    Congress passed a law with special treatment for "recycling companies founded in 1913 in Kenosha, Wisconsin". Of course, there was approximately one family owning company which met those conditions. Shockingly, that family had donated a bunch of money to the Congressman who wrote the clause.

    If the government can make different tax laws for different *groups* of people or companies, if they can favor any group or industry, they can combine those to favor arbitrarily small groups, down to single individuals or companies.

    Either you have a flat tax where everyone pays the same rate, or you let the politicians decide who pays what. They're clever enough (or their donors lawyers are clever enough) to write the rules to benefit the particular donor if you let them write the rules at all.

    > primary reason for that difference is the cost of housing in California. It has nothing to do with government programs and everything to do with the tech sector driving up the cost of housing to bats**t crazy levels

    You seem to have momentarily forgotten how prices are determined - by supply vs demand. If people want more homes like the did here in Dallas, builders build more homes, like they did here in Dallas. If the wood and other materials to build the condo costs $30K and the labor costs $12K, the builder can make a nice profit selling it for $55K. That's what they've done in Dallas.

    I bought my house in Dallas two years ago. I paid $240K for 3,500 square feet. There was demand, and builders supplied.

    Prices go sky high when supply isn't allowed to meet demand - when someone makes it very difficult or impossible to build new housing. In California, that includes things like proposition 13 and CEQA.

    Under prop 13, cities and counties aren't allowed to get much property tax revenue if they allow land to be used for housing; they have to zone it commercial or office so they get much more property tax revenue from a given parcel of land. So each city is very strongly incentived to approve a shopping center being built on a particular piece of land rather than an apartment complex.

    CEQA is another California law that adds an average of 2 1/2 years to each construction project, and sometimes five years, according to the California government's own Legistlative Analysts' Office.

    The costs of both labor and materials is also higher in California. With the largest number of immigrants of any state, you'd think construction labor would be inexpensive on California. Government mandates make it one of the most expensive places to hire people. Materials such as wood and dryall also cost more. With such a large percentage of the nation's timber being produced right there in California and Oregon, lumber should be inexpensive in California, but it's actually cheaper for California's lumber producers to send it half way across the country than to deal with the bureacracy required to sell it in California.

    If the supply of housing matched the demand, you wouldn't have sky high prices. Builders can't suppy the needed housing affordably because of the tens of thousands of pages of red tape BS, and many years of bureaucracy required to even hope that maybe the project will eventaully be allowed to be built.

    This isn't theory. The population of Texas has been growing quickly, including a lot of refugees from California getting tech jobs here, and my 3,500 square foot house actually cost $240,000. It's not maybe getting rid of the nanny state could work; it does work. We're doing it and we've been doing it.

    https://www.census.gov/content...

        That's mostly because all of Californias government programs and edicts cost a lot of money. For example, groceries cost 26% more in Los Angeles than they do in Dallas, because all the extra government red tape and PC bullshit costs the stores a lot more money. Nominal incomes in California aren't bad, but when the government takes $266 billion out of the economy every year (twice as much as Texas) in order to spend $100 billion and ten years failing to build a railroad track, while also burdening everyone with the most expensive pile of ridiculous regulations in the country, including the law regulating cow farts (SB 1383).

    It's helpful to understand what the comment process is all about. The agency publishes a draft of the rule and then people interested can comment on the wording, structure, and details of the draft. The agency then looks at each comment and adjusts the wording where appropriate, where they agree adjustments are needed, in order to produce the final draft. Occasionally, there is a second round of comments, with an interim draft.

    Useful / proper comments which can effect this process point to specific words in specific sections, such as:

I've never seen a policy reversal, or anything remotely resembling a reversal, take place during the comment period. Rather, it's minor adjustments to the details.

    That's the type of comment that gets a change made. The FCC isn't asking what their policy should be, they are looking for bugs in the way they have written the rules.
