SQL Index Manager – a long story about SQL Server, grave digging and index maintenance

Every now and then we create our own problems with our own hands… with our vision of the world… with our inaction… with our laziness… and with our fears. As a result, it seems to become very convenient to swim in the public flow of sewage patterns… because it is warm and fun, and the rest does not matter – we can smell round. But after a fail comes the realization of the simple truth – instead of generating an endless stream of causes, self-pity and self-justification, it is enough just to do what you consider the most important for yourself. This will be the starting point for your new reality.

For me, the written below is just such a starting point. The way is expected to be lingering…

Introduction


At the start of September 2018, some cool guys also joined our team, they are fresh from University and they are really hungry to learn how to design and develop amazing web apps with SAPUI5.


That’s why I’ve started to collects internally on the web some links in order to create “The perfect journey to become a SAPUI5 Ninja Developer”.


I’ve also started to write down some exercise (from easy to hard) in order to test what they’ve learned but I will share those in a second blog post as soon I’ve finished them.


Presentation


Hi everyone,
I'm Emanuele Ricci, a full-stack developer based in Lucca (a beautiful little city in Tuscany, Italy).


Since the last three years, I work full-time for Techedge Group, a big worldwide consultant company that is a partner with SAP. I usually work in projects related with SAPUI5, SCP, HANA and in my free time, I love to create content around the technology I use at work and in my personal projects outside SAP. Lately, I'm a little bit experimenting with Android after the release of SAP Fiori SDK for Android/iOS.

Modes are vim’s killer feature? Seriously?

Reading time5 min
Views2.8K
Author of the original post in Russian: varanio

You may have read a recent article suggesting that vim is great unlike IDEs, because of their allegedly low typing speed.

Let’s recall that the main message of that article was that vim’s killer feature consists in its modes that sort of outshine everything else. That said, the author acknowledged that IntelliJ IDEA and other IDEs provide hotkeys and other user experience which can be easily used. However, since they lack modes, vim is supposed to be everyone’s first choice.

The author then suggests that instead of pressing ctrl+arrows to move between words, it is easier to press Esc, e and then go back to the i editing mode. Understandably, all this trouble because the author finds it inconvenient to hold ctrl.

I know that articles that criticize vim get many negative votes, but I just have to speak out.

The winner of Fhloston Paradise was supposed to be the player paying the very last stake during a 60-block period, before any other player could pay their stake and reset the counter to zero. The winner would collect all stakes paid by other players.

Dmitry's winning recipe was the bot Patrollo, which he created. The bot paid just eight 1 WAVES stakes for Dmitry and eventually won him 4,700 WAVES ($13,100). In this interview, Dmitry discusses his bot and prospects of blockchain games.

Introduction & Recap


In the previous blog post, we learned how to filter, sort and group our table. This is a fundamental aspect of every CRUD application because most of the time users have to deal with hundreds of hundreds of records.


What will be covered on this exercise


With Part 3 of this series of blog posts, we will learn how to create a Master-Detail application leveraging the SplitApp UI control and how correctly configure the app’s manifest to handle routes and targets.


  • SplitApp: UI control that allows you to create a Master-Detail application (used as a replacement of the App control)
  • Routing: we will configure the manifest.json to correctly handle the routing of the application
  • ObjectHeader: control that enables the user to easily identify a specific object. The object header title is the key identifier of the object and additional text and icons can be used to further distinguish it from other objects
  • Navigation to a detail view and bind the element context: you will learn how to navigate and open a detail page and bind the current View (of the detail) to a new context
  • List: in the master page we will use a list to display BusinessPartner because we will have less space

Earlier this week, we released Visual Studio 2019 version 16.1 Preview 1 (see release notes). It’s the first preview of the first update to Visual Studio 2019. If you’re not already set up to get preview releases, then please do that now. The preview channel installs side-by-side with the release channel and they don’t interfere with each other. I highly recommend all extension authors install the preview.




Got the 16.1 preview installed now then? That’s great. Here are some features in it you might find interesting.

Dozen tricks with Linux shell which could save your time

  • First of all, you can read this article in russian here.

One evening, I was reading Mastering regular expressions by Jeffrey Friedl , I realized that even if you have all the documentation and a lot of experience, there could be a lot of tricks developed by different people and imprisoned for themselves. All people are different. And techniques that are obvious for certain people may not be obvious to others and look like some kind of weird magic to third person. By the way, I already described several such moments here (in russian) .

For the administrator or the user the command line is not only a tool that can do everything, but also a highly customized tool that could be develops forever. Recently there was a translated article about some useful tricks in CLI. But I feel that the translator do not have enough experience with CLI and didn't follow the tricks described, so many important things could be missed or misunderstood.

Under the cut — a dozen tricks in Linux shell from my personal experience.
