it (panic ...). Anyway, I learned a lot over the past thirty days, how to find the desired service, how to quickly implement the prototype, and how to compare competing products of developer products... Looking back, the article certainly does not have the Learning 30 Technologies written by Shekhar in 30 Days: A Developer Challenge (and no one has invested so much time and energy ), however, I chose a wider range of technologies (or more messy ones), which is also a process of expanding my hor

(Gnome or KDE) reflect on this. Why should users change the GUI to the Mac GUI after installing your desktop environment? If you do well enough, the user will have nothing to do with it? Search for Theme, test it one by one, and find a Theme you prefer. Isn't it tiring? When chatting with LiveSino's webmaster Picturepan2, we suggested that he be able to try Linux and Mac. As a result, he tried hackathon but refused to use Linux because he didn't like

weights of 1/n respectively.Step 1: Assume an α (t);Step 2: Get the weak classifier H (t);Step 3: Update the overall distribution,whichStep 4: Re-use the new overall distribution to get the next classifier;Think the math in step 3 is scary? Let's break this fear together. First, let's take a quick look at the parameters in the index, α denotes a learning rate, Y is the actual response value (+1 or-1), and H (x) is the category predicted by the classifier. Simply put, if the classifier predicts

, but they need to make sure they continue to grow in their teams. This gives them the opportunity to become an outstanding technology leader, which motivates them to work consistently and effectively and to maintain loyalty to their business.Opportunities for InnovationA game like a hackathon, which allows programmers to play their own coding skills outside of normal work, is very rewarding for both employees and employers. These things and experimen

is wonderful (I highly recommend hackathon).During my stopover from New York to San Francisco, I had a lot of job interviews at various companies and eventually found a job in front-end development at Twitter. To work with an outstanding team there, I could not but tremble with joy, and go to San Francisco, which is also a dream of my life.When the visa was done, I went on a trip to Central and South America, and I developed a small project: a JavaSc

dockerdocumentation.Docker Ecosystem with AzureAs the Docker ecosystem matures, more and more open source projects are emerging.Since the deployment and creation of Docker containers is so fast, how to drive and manage container clusters becomes a huge challenge. The current CoreOS and Google Kubernetes projects are based on automated deployment and management methods that enable dozens of, hundreds or even thousands of container clusters to run on Azure (similar projects include Docker's Libsw

Finger-pounding on the keyboard, big headphones, and a can of energy drinks in the reach of the technology industry are a classic style for traditional programmers. Perhaps the AI we are looking for is in the programming Marathon (hackathon). The developer builds the model and then breaks the model. They get the title of the developer in a variety of different ways, and they have different backgrounds, but one thing is certain, however, that companies

co-operation is worse than doing things alone.So, how do you make an amateur project less lonely?We are not sure, but there is a hypothesis. This hypothesis is based on the wonderful memories of our childhood participation in a nasty science and math contest. It's fun because the whole group of other kids is doing the same thing.We don't know if we can recreate some of the magical and friendly challenges to complete more amateur projects. Like the Science Olympiad, the online

目录[-] --> Million red envelopes, fiery open!!! Have you more wonderful! "How did you learn all these frameworks and languages?" "Recently, a friend in the hackathon asked me."In fact, it's very simple, just use what you want to learn to create a suitable and worthwhile project," I replied."Really?" Do you want to get started with the project directly? "he asked curiously."Yes, and ask for advice from the right people." Smart people are usually happy

Recently, the company has an internal competition (hackathon), enrolled in such a tournament, while preparing the entries (the participating servers need to build their own), taking this opportunity, decided to put the knowledge of the Tomcat deployment from 0 to 1 to re-brush again. I'll be the memo. The FTP server (file Transfer Protocol server) is a computer that provides files storage and access services on the Internet, and they provide servi

For most people, the tech people in their consciousness are Zuckerberg, Steve Jobs, or Bill Gates-Typical Male tech entrepreneurs who often appear in news. In fact, there are still some women in the field of technology, such as Susan wosiki (CEO of YouTube) and Giny romanti (CEO of IBM ). I remember that 15 years ago, the high school information technology teacher said that if she invented a Windows system, she would never design a four-party folder, and the program would be more intuitive. So w

development of better algorithms through events suchAs this, it is now not only quite feasible but rapidly becoming a way of doing business in production industries.This event, the musicData Science hackathon, is clear evidence of that because it involved the music giant EMI MusicSharing its highly prized EMI millionInterview dataset for the very first time. this is a vast and uniquely rich dataset compiled from 20-minute interviews with 800,000 musi
