User evaluation of the content of the website

wmetric.comLet me introduce a small project that nevertheless can be useful. Web metric ( wmetric.com ) allows visitors to rate any article on your website in several ways. Using Web metrics, your website visitor will be able to say more than plus/minus, and he doesn't need to waste time writing a review. Integrates just copied, pasted and working, to install registration is not required.

The vote contains 4 parameters that seemed the most common (interesting-boring, useful-useless, reasonable, silly, competent-incompetent). The average values for each parameter are displayed as arrows: positive assessment — arrow-up, negative-down. The longer the arrow the higher the score. In addition, a single synthetic parameter, "percentage of ideal". It is believed he calculates the Euclidean distance from a particular set of values (a vote) to a maximum of "good", "perfect" point, then this distance is divided by the maximum possible distance from this point in the space of possible votes. The meaning of this parameter: how close the article is to the ideal. If the parameter is set to 0% so the article sucks, but if 100% means the article is perfect.

Are offered the option of voting "only positive reviews" and "positive and negative". In the first embodiment, the user vote only in the positive region, for example, can assess how "smart" article, but may not be as "stupid". This option is probably better suited to the author's sites — no one wants negative ratings in their own diocese. In the second option, voting is possible both positive and negative, allowing, for example, various authors in the competitive mode to measure their works within the boundaries of a single site.

User authorization when voting takes place via one of the social networks. Long-lived session, so a vote for the next site visitor will not need to re-login even if he comes next time to your website through the month.

I will be glad to hear your expert comments and advice.

Approval of WSUS updates: import, export, copy

Изображение
the Backstory Until recently, I worked as edikasyon a major Russian company that has many offices throughout the country. In my jurisdiction there were eleven sites, located in different cities of the Far East (this is important). In each of these offices had its own, not connected with other network infrastructure — your domain AD own subnet, etc. Once the leadership gave me the task to organize the automatic updating of the OS and programs from MS and allowed to expand on accountable sites WSUS . Problem After WSUS was deployed, binding policy, computers to WSUS groups are configured, the directory synchronization content server MS held, etc., the question arose: who and how will approve the update? Imagine 11 cities that are so "fast" and "stable", that rare moment when latency of ICMP replies are only 800 MS, are perceived as unheard of luck. And in each you test all updates before deploying. The access to the servers at the sites was only v

The Hilbert curve vs. Z-order

Repeatedly heard the opinion that of all swept curves . it the Hilbert curve the most promising for spatial indexing. The explanation given is that it does not contain discontinuities and therefore in some sense “well-arranged”. Whether so it actually and what is the spatial indexing, we will understand under the cut. The concluding article of the series: the the Why doesn't the straightforward approach to spatial indexing swept curves the Presentation the 3D and obvious optimization the 8D and perspectives OLAP the 3D field as it looks the 3D field benchmarks the How about indexing non-point objects? The Hilbert curve has the remarkable property — the distance between two successive points is always equal to one (step current of detail, to be precise). Therefore, data is not much different Hilbert curve values are close to each other (the inverse, incidentally, is wrong — adjacent points may be very different in meaning). For this property it is us

Kaspersky Security Center — the fight for automation

oddly enough, I found habré only one article on the subject — the sandbox much unfinished actually contains a piece of the slightly redesigned the product help. Yes, and Google query klakaut silent. I'm not going to tell you how to administer the hierarchy of Kaspersky Security Center (hereinafter KSC) from the command line — I do not yet need never. Just want to share some thoughts about automation tools to those who need it and disassemble one case with which I had to face. If you, %habrauser%, this topic will be interesting — welcome under kat. Historically, the anti-virus protection on the job, I prefer products of Kaspersky Lab (hereafter LK). Causes and other Holy war of personal opinions, I'll leave behind the scenes. Naturally, I would like to centrally deploy, protect, to protect and to enforce the law to draw beautiful graphics to integrate into existing monitoring systems and to do other work shifting the blame to a healthy server. And if you deplo
