And one must remember that with every coyote caught and all those people stopped, the funds necessary to have them take people across the border will also start to dry up. -Barry Levy Redondo Beach Re: “Injunction puts exit exam on hold” (May 13): I read with interest the comments about kids graduating from high school who can’t pass an eighth-grade math test. The question everyone seems to be asking is: Why did they graduate from the 12th grade? A better question: Why did they graduate from the eighth? -Stephen Booth Simi Valley Border Band-Aid Re: “6,000 troops along border” (May 16): With Karl Rove’s help our president always says the right thing, but he never does the right thing! Sending those National Guard troops down there as support for the Border Patrol is like putting a Band-Aid on a severed limb. -Bernard Lehrer Ventura Deal with the devil Re: “Parkman deal first in LAUSD” (May 16): As a retiring teacher from Granada Hills Charter High School, I am disappointed with the outcome of the charter movement and Parkman Middle School. I think Parkman’s teachers have made a “deal with the devil.” They have settled for less than they should have. Why not push the envelope and go all the way to becoming a charter school? I think they will find that the LAUSD does not mean to give them any more freedom. Eventually they will have to take the step to become a charter school or stay and be part of a system that does not believe in giving anything. It is a sad day when a school that was so close to escaping backs down for less than it wanted. -Stephanie Schwartz Canyon Country Beyond disgusted I am a Republican, and beyond disgusted with Bush. In his speech, he mentioned that illegal immigrants should not have an automatic path to citizenship. In that, he implies that some could become citizens eventually. Foreigners breaking our laws to come here for money should never be allowed to become voting citizens. Stay here, maybe, but citizenship, never. I no longer contribute to the GOP; instead, the Minutemen get my donations. -Glenn Victor Northridge Spanish only Re: “Latino students take issue with limited classes” (May 15): My condolences to the high school students who feel cheated because Spanish is the only foreign-language option available to them these days. Isn’t it ironic how illegal immigration hits everyone? Financial constraints are felt everywhere. Couple the extra expense that the LAUSD fields from educating illegals with the hefty pensions and salaries of all the employees, and cuts have to be made. And, goodness knows, Roy Romer isn’t going to take a pay cut. -Kim Greene Studio City Smith responds Re: “Fiscal restraint” (Our Opinions, May 16): As a member of the City Council’s Budget Committee with a record of strong fiscal constraint and advocacy for government efficiency, I am certainly not “loath to see public funds not be spent.” It is that very fiscal philosophy that has guaranteed Los Angeles the highest credit rating of any large city in America. Neighborhood councils receive public money specifically to spend on projects for public benefit. The unused money goes back to the general fund because their use of funds is subject to oversight and transparency, just like all public agencies entrusted with taxpayer money should be. Despite being so new, neighborhood councils have done some wonderful projects, and I want to encourage that. That is why I authored a motion to allow neighborhood councils to “save up” their funding so that they can use it for more ambitious projects that benefit the public, as long as there is a proper and transparent review process. -Greig Smith Los Angeles city councilman Image problem My brother, visiting from Chicago, saw the headline “Phonies flocking to L.A” (May 15).

German firm wins major SA solar contract

first_img3 December 2013A German company has landed its biggest ever solar contract – thanks to South Africa’s renewable energy programme for independent power producers.Juwi AG, which has its headquarters in Worrstadt, will provide engineering, procurement and construction services for an 86-megawatt (MW) solar park in Prieska in South Africa’s sun-drenched Northern Cape province, the company said in a statement last week.Juwi will be working with Sonnedix, an independent solar power producer based in Amsterdam, which landed the contract as one of six solar projects awarded in the third round of South Africa’s Renewable Energy Independent Power Producers Procurement Programme (REIPPP).Sonnedix’s South African partners include Mulilo Renewable Energy and Ixowave Women in Power.Known as the Mulilo Sonnedix Prieska PV solar park, it will be larger than any PV plant currently on line on the African continent, and will be Juwi’s fifth project in South Africa.“The project … represents an investment of more than R1.2-billion,” Olivier Renon, South Africa country manager of Sonnedix, told news website PV-Tech last month. He said construction was expected to begin in the second half of 2014, and the park should start generating electricity to the South African grid by the end of 2015.Under the government’s Integrated Resource Plan, a 20-year projection on electricity supply and demand, about 42% of electricity generated in South Africa will have to come from renewable resources. The Department of Energy’s REIPPP, introduced in August 2011, will help meet this target.The programme has helped investment grow from “a few hundred million dollars” to US$5.7-billion last year, according to the Renewables 2013 Global Status Report published in July by REN21, the global renewable energy policy network.SAinfo reporter, Juwi and PV-Techlast_img read more

When NoSQL Databases Are — Yes — Good For You And Your Company

first_imgIT + Project Management: A Love Affair 3 Areas of Your Business that Need Tech Now Tags:#databases#NoSQL Related Posts brian proffittcenter_img The proliferation of non-relational databases in the tech sector these days could lead you to think that these data management tools (also known as NoSQL databases) are eventually going to make traditional relational databases extinct.Not so. Each of these database types is best suited for very different types of workloads, and that’s going to prevent either one from tromping the other into the dust. Which means that IT and other managers are going to have to figure out which approach is best suited for the task at hand.In this two-part series, I’ll examine the capabilities of both NoSQL and relational databases to help you make the right decisions for your organization.“NoSQL”? More Like “Not Only SQL”Right off the bat, NoSQL databases are unique because they are usually independent from Structured Query Language (SQL) found in relational databases. Relational databases all use SQL as the domain-specific language for ad hoc queries, while non-relational databases have no such standard query language, so they can use whatever they want. That can, if need be, include SQL.See also: Relational Databases Aren’t Dead—Heck, They’re Not Even SleepingNoSQL databases are designed to excel in speed and volume. To pull this off, NoSQL software will use techniques that can scare the crap out of relational database users — such as not promising that all data is consistent within a system all of the time.That’s a key result of using relational databases, because when you are conducting a financial transaction, such as buying something on Amazon, databases have to be very sure that one account is debited the same amount that another account is debited at the same time.Because so much of this back-and-forth read-write activity is needed in a single transaction, a relational database could never keep up with the speed and scaling necessary to make a company like Amazon work.According to Bob Wiederhold, CEO of NoSQL database vendor Couchbase, the architecture and features of NoSQL databases bring four key advantages to NoSQL users.Go Big Or Go HomeEasier scalability is the first aspect highlighted by Wiederhold. NoSQL databases like Couchbase and 10Gen’s MongoDB, he said, can be scaled up to handle much bigger data volumes with relative ease.If your company suddenly finds itself deluged by overnight success, for example, with customers coming to your Web site by the droves, a relational database would have to be painstakingly replicated and re-partitioned in order to scale up to meet the new demand.Wiederhold cited social and mobile gaming vendors as the big example of this kind of situation. An endorsement or a few well-timed tweets could spin up semi-dormant gaming servers and get them to capacity in mere hours. Because of the distributed nature of non-relational databases, to scale NoSQL all you need to do is add machines to the cluster to meet demand.There’s No Need To FearPerformance is another way that NoSQL databases can excel. First, every time you add a new server to a NoSQL database cluster, there is performance scaling by virtue of the fact that you’re throwing another processor into the equation.Beyond the scaling advantages, the very architecture of NoSQL tools aids performance. If a relational database had tens or even hundreds of thousands of tables, data processing would generate far more locks on that data, and greatly degrade the performance of the database.Because NoSQL databases have weaker data consistency models, they can trade off consistency for efficiency. In Wiederhold’s social gaming example, if a user updated his or her profile, there’s no real degradation of game performance if that profile’s new info isn’t updated across the entire database instantly. This means that resources can be dedicated to other things, like tracking down that orc that’s about smack you around in-game.Objects Of DesireWhen applications developers have to work with data in relational databases, it can at times be troublesome due to data mapping and impedance issues. In NoSQL databases, this is not usually a problem, because data is not stored in the same manner.With document-oriented NoSQL databases, for instance, data is stored in just that format: documents. And since documents are objects, after all, then programmers who tend to think in object-oriented terms are going to be much more familiar with manipulating such data.That weaker consistency model helps programmers, tool, since their apps don’t have to rigidly conform to data consistency requirements. That makes coding much simpler and (by extension) much faster.Downtime? What Downtime?Wiederhold’s fourth example is a new one to the NoSQL advantage list. It’s something that non-relational databases weren’t specifically designed to do, but at which they’ve nonetheless turned out to be proficient.Because of their distributed nature, Wiederhold says, NoSQL databases can be pretty much always on. This is a huge advantage for web- and mobile-based businesses that can’t afford to be down for a single moment.With some advanced planning, software updates and hardware upgrades can be performed while the database is still running hot. Try doing that with a relational database without taking it down, and you’re in for a world of trouble.get section where name = ConclusionNoSQL databases’ advantages sound great, and they are — for the right use case. If your company has a data set that will remain relatively constant in size, or that only grows slowly, you’ll have little need to migrate to a non-relational system.If sudden growth, agile development or high performance are something your organization will need for its data, then you should take a look at the NoSQL class of databases and see what might be a fit for you.Image courtesy of Shutterstock Massive Non-Desk Workforce is an Opportunity fo… Cognitive Automation is the Immediate Future of…last_img read more
