A lot of strange stories recently. Peter tu, an engineer at GE, compared his professor to a vampire and compared industrial engineers to a wolf. "Vampires need blood from human donors. Professors need publications, which they extract from their grad students."-Peter TU A few weeks ago I attended two conferences: the European Conference on Computer Vision (eccv) and the IEEE Conference on advanced video and signal-based surveillance (AVSS ). at both events I was invited to particle on the vis

This interesting article is from the blog of Tomasz Malisiewicz. It is a blog of Peter Tu (see the original article ). Peter Tu is from Computer VisionGroup of ge Global Research. Tu's analogy between researchers from academia and industry with those from the werewolf, vampire, and undead supernatural species is true. In fact, some problems were also explained in the joke. Therefore, Liao was inspired and entitled to be entertaining. Below is the original text + simple excerpt. A few week

Of course, you may want to download more than one file.

running this program is a bunch of useless garbled characters. The xinxi.txt file cannot be output because the readchar function reads a 16-bit Unicode character, while system. Out. Print uses it as an eight-bit ISO Latin-1 character output. ---- Java 1.1 introduces a new set of readers and writers interfaces to process characters. We can use the inputstreamreader class instead of datainputstream to process files. Modify the above program as follows: Import java. Io .*; Public class RF {Public

The supported data includes scanned aerial photos, aerial digital photos projected from the frame center (such as vexcel ultracamd), and aerial digital photos projected from the line center (such as ads40), push Scan satellite (such as alos prism/avinir, Aster, CARTOSAT-1, FORMOSAT-2, GeoEye-1, IKO

Debugging Grok expressions on the terminal command line in Ruby People with Logstash know to debug Grok regular expressions on http://grokdebug.herokuapp.com.

Therefore, it is necessary to quickly debug on the terminal by means of command line. In fact, when Logstash was still in his 1.1, the official wiki was a group of people who taught us
