Sadly, a flatbed truck dumping 7,5. Oregon will not be the weirdest story of 2. It will not evenbeclose. Still, the situation warrants some kind of scientific explanation, since it’s not every day that the mucus of a living fossil destroys a Prius. WKRG reports that yesterday, local authorities in Lincoln County, Oregon were alerted of an overturned truck on Highway 1. Cheatbook your source for Cheats, Video game Cheat Codes and Game Hints, Walkthroughs, FAQ, Games Trainer, Games Guides, Secrets, cheatsbook. The flatbed had ostensibly spilled slimy hagfish over the road, severely damaging one unlucky Prius. No one was injured physically, at least. The psychological damage can’t be quantified. In what was surely the most thrilling day in the history of the Oregon Department of. Despite their nicknames—“slime eel” and “snot snake”—these creatures are neither eels nor snakes.“. Also, if there’s slime, it’s a hagfish.”According to Thaler, the Pacific Northwest has a pretty active hagfish fishery. This particular shipment of hagfish was bound for South Korea, where they are considered a delicacy. The obvious question here is, what’s up with all that mucous? Do hagfish hate modern highway infrastructure or harbor some sort of vendetta against Priuses? Apparently, the hagfish uses slime for self- defense against predators or alternatively, for hunting prey.“The slime provides protection and helps isolate food,” Thaler explained. When they feed on a carcass, the slime pours out, covering the carcass and preventing other scavengers from encroaching on their food.”Though it looks gross, hagfish slime is actually something of a wonder material. Because it’s made of protein and sugar molecules known as mucin, hagfish mucous doesn’t dries out and harden over time—it stays all gooey. But that doesn’t mean the mucous is weak, in fact, quite the opposite. Hagfish mucous also contains thread- like proteins that are incredibly tough, so much so that researchers are trying to figure out how they can use the slime to stop bleeding in accident victims, or make sustainable fabrics for clothes. Even the U. S. Navy is interested in engineering it for defensive materials against missiles. The humble hagfish produces a sticky slime to defend itself from predators, as well as to hunt for.

What’s the Difference: New Adobe CC 2. CS6, CS5, CS4, CS3? The all- new Adobe CC 2. Sometimes outside car thermometers are so inaccurate that they feel like random number generators. They’re basically the worst feature of the car, next to the car. Why Your Car Thermometer Is So Bad at Telling the Temperature. Sometimes outside car thermometers are so inaccurate that they feel like random number generators. They’re basically the worst feature of the car, next to the car’s infotainment systems. That’s because they’re not actually thermometers, they’re actually thermistors. What’s the difference? Unlike a thermometer, which measures heat, a thermistor measures the changes in electrical current after heat is added or removed. Thermometers and thermistors do really similar things, so this isn’t why your car is so bad at measuring outside temperatures (but we’re still appalled and kind of upset that it’s not a thermometer). The real reason is the thermistor’s placement. Most thermistors are at the front of the car behind the car’s grille (which is normally between the two headlights). This makes the reading a lot less accurate, especially on hot, sunny days because it also picks up on the heat radiated from the road. Measurements are most accurate when you’re traveling at quick speeds and at times when the sun isn’t hitting the road, like at night and during cloudy weather.
Your car thermistor can still be helpful in measuring below- freezing or freezing temperatures during cold weather, but it’s important to note that it isn’t that precise. You can still use it to look at changing temperatures in different areas, but we recommend having a good weather app in the meantime. Like most ways of measuring things, the United States uses a different temperature scale than most. On the surface, Scan works like all those others apps out there: point your camera at the document, and snap a picture.

This article is about software which browses the web. For the search engine, see Web. Crawler. For software that downloads web content to read offline, see offline reader. Web crawlers can copy all the pages they visit for later processing by a search engine which indexes the downloaded pages so the users can search much more efficiently. Crawlers consume resources on the systems they visit and often visit sites without approval. Issues of schedule, load, and . Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent. For instance, including a robots. As the number of pages on the internet is extremely large, even the largest crawlers fall short of making a complete index. For that reason search engines were bad at giving relevant search results in the early years of the World Wide Web, before the year 2. This is improved greatly by modern search engines; nowadays very good results are given instantly. Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping (see also data- driven programming). Nomenclature. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds them to the list of URLs to visit, called the crawl frontier. Download activated games for your pc.

War Machine is no one else but Tony Stark's best friend, who took one of his suits in order. URLs from the frontier are recursively visited according to a set of policies. If the crawler is performing archiving of websites it copies and saves the information as it goes. The archives are usually stored in such a way they can be viewed, read and navigated as they were on the live web, but are preserved as . The repository only stores HTML pages and these pages are stored as distinct files. A repository is similar to any other system that stores data, like a modern day database. The only difference is that a repository does not need all the functionality offered by a database system. The repository stores the most recent version of the web page retrieved by the crawler. The high rate of change can imply the pages might have already been updated or even deleted. The number of possible URLs crawled being generated by server- side software has also made it difficult for web crawlers to avoid retrieving duplicate content. Endless combinations of HTTP GET (URL- based) parameters exist, of which only a small selection will actually return unique content. For example, a simple online photo gallery may offer three options to users, as specified through HTTP GET parameters in the URL. If there exist four ways to sort images, three choices of thumbnail size, two file formats, and an option to disable user- provided content, then the same set of content can be accessed with 4. URLs, all of which may be linked on the site. This mathematical combination creates a problem for crawlers, as they must sort through endless combinations of relatively minor scripted changes in order to retrieve unique content. As Edwards et al. A 2. 00. 9 study showed even large- scale search engines index no more than 4. Web. The importance of a page is a function of its intrinsic quality, its popularity in terms of links or visits, and even of its URL (the latter is the case of vertical search engines restricted to a single top- level domain, or search engines restricted to a fixed Web site). Designing a good selection policy has an added difficulty: it must work with partial information, as the complete set of Web pages is not known during crawling. Cho et al. Their data set was a 1. One of the conclusions was that if the crawler wants to download pages with high Pagerank early during the crawling process, then the partial Pagerank strategy is the better, followed by breadth- first and backlink- count. However, these results are for just a single domain. Cho also wrote his Ph. D. The explanation given by the authors for this result is that . It is similar to a Pagerank computation, but it is faster and is only done in one step. An OPIC- driven crawler downloads first the pages in the crawling frontier with higher amounts of . Experiments were carried in a 1. However, there was no comparison with other strategies nor experiments in the real Web. Boldi et al. The comparison was based on how well Page. Rank computed on a partial crawl approximates the true Page. Rank value. Surprisingly, some visits that accumulate Page. Rank very quickly (most notably, breadth- first and the omniscient visit) provide very poor progressive approximations. One can extract good seed from a previously- crawled- Web graph using this new method. Using these seeds a new crawl can be very effective. Restricting followed links. In order to request only HTML resources, a crawler may make an HTTP HEAD request to determine a Web resource's MIME type before requesting the entire resource with a GET request. To avoid making numerous HEAD requests, a crawler may examine the URL and only request a resource if the URL ends with certain characters such as . This strategy may cause numerous HTML Web resources to be unintentionally skipped. Some crawlers may also avoid requesting any resources that have a . This strategy is unreliable if the site uses URL rewriting to simplify its URLs. URL normalization. The term URL normalization, also called URL canonicalization, refers to the process of modifying and standardizing a URL in a consistent manner. There are several types of normalization that may be performed including conversion of URLs to lowercase, removal of . So path- ascending crawler was introduced that would ascend to every path in each URL that it intends to crawl. Cothey found that a path- ascending crawler was very effective in finding isolated resources, or resources for which no inbound link would have been found in regular crawling. Focused crawling. Web crawlers that attempt to download pages that are similar to each other are called focused crawler or topical crawlers. The concepts of topical and focused crawling were first introduced by Filippo Menczer. A possible predictor is the anchor text of links; this was the approach taken by Pinkerton. Diligenti et al. The performance of a focused crawling depends mostly on the richness of links in the specific topic being searched, and a focused crawling usually relies on a general Web search engine for providing starting points. Academic- focused crawler. Other academic search engines are Google Scholar and Microsoft Academic Search etc. Because most academic papers are published in PDF formats, such kind of crawler is particularly interested in crawling PDF, Post. Script files, Microsoft Word including their zipped formats. Because of this, general open source crawlers, such as Heritrix, must be customized to filter out other MIME types, or a middleware is used to extract these documents out and import them to the focused crawl database and repository. These academic documents are usually obtained from home pages of faculties and students or from publication page of research institutes. Because academic documents takes only a small fraction in the entire web pages, a good seed selection are important in boosting the efficiencies of these web crawlers. This increases the overall number of papers, but a significant fraction may not provide free PDF downloads. Re- visit policy. By the time a Web crawler has finished its crawl, many events could have happened, including creations, updates, and deletions. From the search engine's point of view, there is a cost associated with not detecting an event, and thus having an outdated copy of a resource. The most- used cost functions are freshness and age. The freshness of a page p in the repository at time t is defined as: Fp(t)=. The age of a page p in the repository, at time t is defined as: Ap(t)=. They also noted that the problem of Web crawling can be modeled as a multiple- queue, single- server polling system, on which the Web crawler is the server and the Web sites are the queues. Page modifications are the arrival of the customers, and switch- over times are the interval between page accesses to a single Web site. Under this model, mean waiting time for a customer in the polling system is equivalent to the average age for the Web crawler. These objectives are not equivalent: in the first case, the crawler is just concerned with how many pages are out- dated, while in the second case, the crawler is concerned with how old the local copies of pages are. The visiting frequency is directly proportional to the (estimated) change frequency. In both cases, the repeated crawling order of pages can be done either in a random or a fixed order. Cho and Garcia- Molina proved the surprising result that, in terms of average freshness, the uniform policy outperforms the proportional policy in both a simulated Web and a real Web crawl. Intuitively, the reasoning is that, as web crawlers have a limit to how many pages they can crawl in a given time frame, (1) they will allocate too many new crawls to rapidly changing pages at the expense of less frequently updating pages, and (2) the freshness of rapidly changing pages lasts for shorter period than that of less frequently changing pages. In other words, a proportional policy allocates more resources to crawling frequently updating pages, but experiences less overall freshness time from them. To improve freshness, the crawler should penalize the elements that change too often. The optimal method for keeping average freshness high includes ignoring the pages that change too often, and the optimal for keeping average age low is to use access frequencies that monotonically (and sub- linearly) increase with the rate of change of each page. In both cases, the optimal is closer to the uniform policy than to the proportional policy: as Coffmanet al. Cho and Garcia- Molina show that the exponential distribution is a good fit for describing page changes. Needless to say, if a single crawler is performing multiple requests per second and/or downloading large files, a server would have a hard time keeping up with requests from multiple crawlers.
