As front-end ecosystems develop rapidly, we spend time trying new technologies and discussing them online. As front-end ecosystems develop rapidly, we spend time trying new technologies and discussing them online. I don't mean it shouldn't be the case, but maybe we can slow down and pay more attention to things that haven't changed much. These things can greatly improve the quality of work, increase the value of work, and help us understand new tools.
In this article, I have my past experiences
Entity Framework 6 Recipes 2nd Edition (12-3), entityrecipes
12-3. database connection logs
Problem
You want to record logs for each connection and disconnection from the database
Solution
EF exposes a StateChange event for the DbContext connection. We need to handle this event and record logs for each connection and disconnection with the database.
Suppose our model is shown in Figure 12-3. in the Listing 12-3 code, we create some Donation instances and save them to the database. the code here
msg. MemberId, count (msg. MessageId) as MessageCount
From chapter10.message msg where datesent = @ datesent
Group by msg. MemberId
) Temp on m. MemberId = temp. MemberId
Order by temp. MessageCount desc

There have been so many changes in this short year (about app development): in front of the attractive swift, we almost forget how obsessed with objective-c, and the imaginative iOS 8 and watchkit, it's hard to imagine what API can compare with it.Nshipster's practice: Please lov

The last two weeks after the official release of Fedora13, the development of the next generation of Fedora14 has been launched. The first step is to get a code. Fedora13, codenamed Goddard, is an American physicist, Robert Goddard, the first rocket engine inventor in the United States. It is recognized as the father of modern rocket technology and has created the first in the history of rockets, A total of 214 patents were obtained. The ora14 Code al
The Fedora14 development code, Laughlin, was named by the Nobel physics prize winner, Robert TB. laughlin, Fedora is a RPM-based Linux release, sponsored by RedHat and developed by the community-supported FedoraProject project. Fedora only contains free and open source software. New Features of Fedora14 include GNOME2.32 and KDE4.5.

completely random passwords. For a completely random password, only brute-force cracking is feasible. At this time, the speed becomes the 'most important factor '."
However, the password cracking speed has also been improved. For example, by using a computer with a single video card, the oclHashcat-plus program can guess hundreds of thousands to billions of combinations of passwords per second, depending on the hash algorithm used for encryption entries in the password file.
Tarjan algorithm for the strong connected component of the graph is named after its inventor Robert Tarjan. Robert Tarjan also invented the Tarjan algorithm for dual-connected components, as well as the offline Tarjan algorithm for recent public ancestors, where Tarjan expressed a high respect.Attached: C + + program for Tarjan algorithmvoid Tarjan (int i) {int J; Dfn[i]=low[i]=++dindex; Instack[i]=t
closely related to the Tarjan Algorithm for Finding undirected graph's dual-connected components (cut points and bridges. Learning the Tarjan algorithm also helps you to deeply understand the Tarjan Algorithm for dual-connected components. The two can be compared and combined.
The Tarjan algorithm used to calculate the strongly connected component of a directed graph is named after its inventor Robert Tarjan. Rob

In dr. although the blog I saw on the Dobb website has been around for a while now, and a lot of content is more theoretical, Or I feel a little touched when I need some work experience, so after a while, you may have different experiences when looking back at these articles. There is also a link to "10 papers that developers should read", which is also a good article.
10 papers every software architect shocould read (at least twice) Earlier today I read a post by Michael feathers called "10 pap
A famous software company held a job fair today. It is interesting to have such a question. The recruitment questions are as follows:
Donald + Gerald ---------- Robert has a total of 10 letters. Each letter represents one of the 0-9 Arabic numerals. If R = 7 is known, calculate the numbers represented by the other 9 letters. The answer is as follows: (1) 2D = T, meaning T is an even number. (2) 2L = r, think R = 7, and 2L is an even number, which indi

Sometimes this means manual manufacturing control is needed, said Monroe. "I will let the patient go to the bathroom to flush the toilet. Such behavior, or other seemingly meaningless similar behavior, can break the continuous stress cycle and divert the impact of the current stress to other transactions ." Such means can help to direct the pressure to the "available level, at which people gain a sense of control and turn negative pressure into benign pressu
