The Entry the library Itself is pretty Mature — first release on github is dated already 2004. I was surprised when Habr in search engine didn't give me any links to articles that mentions about this wonderful library. SOCI supports ORM via a type_conversion specialization. SOCI has backends for: DB2 Firebird MySQL with specific ODBC database driver Oracle PostgreSQL SQLite I'm not going to translate manuals or give here the code from examples and try to adapt (change table structure and other simplifications) code from your last project, that was evident and interesting.

When your computer is infected with cryptologia if your passwords are stolen with a Trojan and fraudsters stole mail if phishing stole your credit card and withdrew money — it's all awful, but at least that explains what happened and how to deal with it. Antivirus to clean out the muck, restore data from a backup (unless of course he is), reissue the card. Much worse, if you quietly, without attracting attention, for a long time watching. Usually, this threat is relevant for public figures, large companies in General, in cases where you own real valuable information. Or not only: it seems that cybercriminals intermediate level also begin to try to play in cyber-espionage. Researchers from the Chinese team 360 Netlab were able to identify at least 7500...

To Saint TeamLead Conf conference team-lead about the pain remained for two weeks. In this conference we have not just wanted to indicate as many problems as possible, and wanted to open each topic from different points of view. We the program Committee, based in particular on the February TeamLead Conf, gathered together all the main activities team-lead (let's not forget that while all are investing in this role different). Received, compiled, structured and used like bricks to build the program: communication; measurement and evaluation; working with knowledge; building the team and building; team motivation; and work, which includes the same: "I became timida, and that now". the Schedule is, I think, a very balanced and balanced, for each of the 10...

Wanted to sleep today, but again failed. In the Telegram there was a message that someone is not going to Java... and we woke up only a couple of hours, tired and satisfied. to Whom this post may be useful? Yes, probably, to anyone except those who also collects JDK8 or just likes to read a dreadful horror. In General, I warned you, close the article immediately. Problem three: Not going to (first) Very boring part you can skip. Only needed for those who want to fully restore the history of events; Not going (level two) more Interesting, because there are a couple of typical errors, necromancy, necrophilia, BSD is better than GNU/Linux and why you should upgrade to the new versions of the JDK. Even if it is falls into the cortex More interesting. Yahuuu...

Good day to All! Our lovely Vitaly Ivanov, lecturer of the course "Java Enterprise Developer" held last week webinar on the topic "CDI in action" is about one of the key specifications of the Java Enterprise stack — Contexts and Dependency Injection 2.0. The lesson was generally understood patterns of IoC and DI, and the example of the reference implementation Weld held familiarity with Managed Beans, methods for their introduction and context definition, plus dismantled these capabilities specification, such as interceptors, decorators and alternatives. If you have any questions and comments you can leave them here or ask them directly Vitaly, go to the open day.

Article published on 23 December 2017 Introduction the best option in electronics manufacturing — when all the components are original from the manufacturer, but what if you have beushnye microcontroller, which will not live long? If the transistor in the protection circuit input voltage is out of specification? Then your product will have serious problems. The microcontroller can fail and the chain will not cope with the load. actually, it's not your fault and not the fault of the design. The reason — in fake chips. You can say, "Chip microcontroller correctly tagged and looks like the original — that's for sure." And I answer: are you sure that inside the correct crystal?! On the counterfeits it is possible to earn fabulously. In the study of the...

Hard drives are approaching the limits of its development, and the film becomes only better with time. Financial institutions require companies to store more data and increasingly long period of time. The amount of data that have to store each year increases by 30-40 percent compared to the previous year. The hard drive capacity is also growing, but with half the tempo. Fortunately, all of this information does not require instant access, so the film is a great solution to the problem. Read more →

At the beginning of 2017, we, the development team for QIWI Terminals, collected the wishes of the departments of the company — to find out what are the global challenges colleagues would like to solve with our help, to make life easier. most pleased with the request of customer service, working with calls and pretensional from taxpayers: “There is a problem: the client makes a payment terminal, but the processing it never comes — or the terminal might hang or Internet working via gsm modem fell off. And it turns out that the check is the client and payment in the system. It would be good in such cases to learn how to deliver payments in QIWI. There is also a group of anxious customers who are immediately after make the payment, dial the call center to...

If you work in a company, which falls under action # 187-FZ ("On the security of critical information infrastructure of the Russian Federation"), then you don't need to explain what Goscopy and why it is needed. For the rest explain Goscope stands for a State system of detection, prevention and elimination of consequences of computer attacks. Architecturally it is a single geographically distributed set of centres of various sizes, sharing information about cyberattacks. Such centres are obliged to create all the companies which belong to the objects of critical information infrastructure (such companies are called subjects CUES). The purpose of all this massive government initiative to create between the most important organisations for the exchange of...

Last week I visited the IFA exhibition in Berlin in 2018, which took place from 31 August to 5 September in the exhibition complex Messe Berlin. This event with a very long history, which was first conducted in Germany in the 1920-ies. Not for nothing, IFA stands for Internationale Funkausstellung, that is "international radioactive". Today it is the largest exhibition of electronics and household appliances, one of the most important in the world. It come to professionals from different countries, including USA, China, Korea, and Japan. the last time I was on it in 2014, I decided to go and at the invitation from the University (read more about the study at the University in Germany recently published an article on habré). so, what was there of interest?...

Vincent VEGA in the Parking lot. Vincent VEGA in the clinic. Vincent VEGA in the town of Kovrov in the Vladimir region... Memes confused with the hero of John Travolta is not only funny, but also true. Who among us has not been in a situation hopeless search facility, when the only remains that shrug? the Two most common approaches to addressing mail and geocoordinates – often powerless in the modern world. Due to an incorrect address 20% of mail is returned to senders. The failure to clearly explain your exact location reduces the client flow businesses who have been unlucky with address. People spend lives and nerves before they find the desired result. Read more →

Renowned Danish brand Bang & Olufsen in the past year introduced a speaker system that is difficult to miss. Another experiment company is famous as the developer of fancy and expensive audio components, equally interesting from the point of view of electro-acoustics, acoustics, design features and design AC. We are talking about Bang & Olufsen BeoSound Shape. Year sales showed that the experimental kit did not become a mass product, but found a niche application as a comprehensive solution for the expensive interiors of private apartments, clubs and restaurants. The system has received a lot of mixed reviews from experts and authoritative edition of “What Hi-fi?” has ranked this multiroom installation for the better as last year. Under the cut detail on...

Disclamer: I have never in my life worked with CAD/CAM applications before, and suddenly had to. The principles of FreeCAD I'm so delighted that this calls for an urgent post on Habr, to tell others. is Written in this post will most likely be trivial and boring for most of the active users of CAD, and this post is aimed primarily at non-CAD users to tell them about the brave new world of computer graphics. the Entry I have a simple task — to make a 3D model of his apartment. Not just a "wall size" and all beams, ledges and bends. I tried one, two, three... I'm desperate (started with SweetHome3D, and ended with blender and inkscape). They were all damned inconvenient. Among the programs that I tried, and FreeCAD, which I missed because of "doing nothing...

Surely everyone has heard about Amazon Web Services (AWS). Some even looked at the Pricing page. And noticed that prices are considerably higher than for DigitalOcean, Linode, Hetzner and the Cloud. Here is the table for price comparison: RAM CPUs Drive Traffic DigitalOcean - 4 GB 2 vCPUs 80 GB 4 TB $20 Linode Linode 4GB 4 GB 2 vCPUs 80 GB 4 TB $20 AWS t2.medium 4 GB 2 vCPUs - - $40 Amazon takes the money for the traffic, and prices are not too low: So what then, Amazon? Here are the reasons I see: a Large number of useful services. a Free Tier. On the second and will be discussed in this article. Read more →

In a recent issue of artificial intelligence has been in the media one of mainstreme and we are increasingly afraid of the prophecies from many famous people, such as from Stephen Hawking (the universe he rest in peace) or Elon musk, about the danger of his development. Such alarmist rhetoric implies that the actual artificial intelligence, first, will be the subject, and secondly, will have negative intentions against both individual people and humanity as a whole. Here on these assumptions, let's talk more. Read more →
