A homepage with 22 external CSS files, more than 100 KB of HTML and 1.2 MB PNG title images in listing views was no longer a charming bit of history. Lighthouse estimated 6.25 MB of image savings. The score moved between 27 and 55 depending on the run. That is not a measurement. It is a weather forecast with a very small cloud. I worked in two rounds.

To understand the algorithms, to learn something new. Over the years, this experiment has grown into a very successful open-source project that has now been downloaded millions of times via NuGet and is used in numerous commercial and private projects worldwide.

Whether you’re controlling smart home devices or looking for a simple setting, instead of a quick response, using the app becomes a test of patience. I had exactly this problem. And the solution is as simple as it is curious. The culprit: Contacts permission In most cases, the cause of performance issues is not your smartphone or your internet connection, but rather an app permission. More specifically: access to your contacts. In my case, the app apparently tried to scan through my 1,000+ contacts every time I changed pages. On a second smartphone with fewer contacts, it worked much faster.

Before we start, however, we will give you a quick introduction to the topic. If you are already familiar with the topic and are only interested in the AJAX cross-domain workaround, you can safely skip the first part of the article. What is AJAX and how does it work in jQuery? AJAX is an abbreviation and stands for “Asynchronous JavaScript And XML”. Contrary to the opinion of some people on the Internet, it is not a programming language, but rather a pattern, i.e. a way of programming something.

Because PHP is not “only” used to create web pages or to implement forms, as any experienced PHP programmer of larger web agencies will surely confirm. Besides functions for text processing, PHP also provides methods for image processing as well as for manipulation on bit and byte level. And these are the ones we want to use today. But before we start coding, we will have a short introduction to the topic of steganography. Steganography is not shorthand As the title already announced, today’s topic is steganography, the art of hiding information or knowledge in a carrier medium. Wikipedia defines steganography as follows: Steganography (/ˌstɛɡəˈnɒɡrəfi/) is the practice of concealing a message within another message or a physical object.

Besides the logic of a secure login or user management system, the secure storage of passwords is one of the most important points during implementation. Even if the actual login code is 100 percent error-free and secure (which should never be assumed in practice), security vulnerabilities in the server software can still lead to intrusions or hacks. There is always a variable that is out of one’s control and thus websites are hacked, compromised and complete databases with usernames and passwords are read every day.

Those can skip ahead to the section “Wildcard operator in Google Suggest”, for all others here is the quick start. Google Suggest is the name of the Google functionality that is responsible for suggesting possible search queries while you are typing your search query. For example, if you type “What are the most popular”, Google will suggest “What are the most popular sports in Australia”. The suggestions, in turn, are based on the one hand on the user’s own Google search profile and on the other hand on the most frequent search queries currently sent to Google by other users. For webmasters, SEOs (search engine optimizers) and Internet marketers, however, the Google Suggest feature has a completely different benefit than [...]]]> https://en.code-bude.net/2021/09/06/wildcards-in-google-suggest-nutzen/feed/ 0 https://en.code-bude.net/2021/09/06/how-to-clear-dns-cache-on-all-kind-of-systems/ https://en.code-bude.net/2021/09/06/how-to-clear-dns-cache-on-all-kind-of-systems/#respond Mon, 06 Sep 2021 09:36:27 +0000 https://en.code-bude.net/?p=1550 https://en.code-bude.net/2021/09/06/how-to-clear-dns-cache-on-all-kind-of-systems/feed/ 0 https://en.code-bude.net/2018/04/29/restore-unsaved-documents-in-word/ https://en.code-bude.net/2018/04/29/restore-unsaved-documents-in-word/#comments Sun, 29 Apr 2018 17:41:39 +0000 https://en.code-bude.net/?p=1439 I think almost everyone knows the scenario: You work on a Word document and either Word itself or the entire computer crashes. In order to prevent a total loss of the document, Word can activate the so-called “auto save” function, which saves the document automatically every X minutes. So in a crash only the changes since the last automatic save are lost. But what if you had not saved the document yet? In this case, Word does not automatically restore the document. But here, too, is one last salvation. We want to look at both tips in the following. Enable automatic saving in Word First, the automatic save should be activated.

Every few months I write smaller projects with Node.js. But before I start, I’d like to update to the latest version, and that’s where the dilemma starts.

This time it’s about how to read account balance, sales and transactions and other things of a Paypal account. First some basic information. Although Paypal is an “online account”, in many ways it differs from an online (giro) account of a “classic” bank. For example, Paypal does not support the Homebanking Computer Interface (HBCI) to retrieve account information or send payments. Instead, Paypal offers different APIs (REST, SOAP, + SDKs, …), which differ not only in structure and technology, but especially in the range of functions. For our purposes we will use the so-called “NVP / SOAP API” and connect [...]]]> https://en.code-bude.net/2018/02/21/check-paypal-account-balance-and-transactions-via-csharp-api/feed/ 2 https://en.code-bude.net/2018/02/14/send-push-notifications-c/ https://en.code-bude.net/2018/02/14/send-push-notifications-c/#comments Wed, 14 Feb 2018 19:17:26 +0000 https://en.code-bude.net/?p=1398 In today’s article, we’ll look at how to push notifications out of C# onto smartphones or other devices. It does not matter if it is an Android or an Apple / iOS device. But when do you need such functionality? For example, I run a few niche sites (affiliate websites) with which I earn monthly through affiliate programs. However, the revenue reports have to be picked up proactively in almost all affiliate programs. So I wrote a small C# client, which regularly downloads the reports and sends me a push notification for new sales. That’s just one of many uses and I’m sure you’ll think of a few more.

Today, it’s more like geo-blocking – locking out certain users based on their country of origin. However, both variants are based on the same technique: the evaluation of the IP address. In the first case, accesses from an IP address are counted (in addition to cookies) – in the second case, a database is used to evaluate where in the world the user behind a specific IP address is staying. Both locks can often be bypassed by changing the IP address. There are several ways to change the IP address.

So fields, such as first name, surname, street, e-mail address, etc. So far I have oriented myself to given requirements or old databases. But now I wanted to work up the topic once for all right.
