Why am I griping about Gitee on my own blog instead of reporting it to Gitee? Because that's one of the things I'm griping about. Their issue workflow is broken too: I filed an issue, an official replied and rejected it, and once rejected I could no longer respond — so here I am, griping on my own blog.
This tool uses the webmaster tools or open platform APIs of Baidu, Bing and Google to push site updates to search engines immediately, speeding up crawling and indexing.
Let's be clear about this: Java threads have 6 states. Online — including the copy-paste crowd on CSDN who mindlessly repost who-knows-what — everyone says 5. I went and read the docs myself, and I'm certain it's 6.
Last time we looked at the Thread class and the Runnable interface, but that pairing has one problem: no return value. If we want the thread to hand a value back, we need FutureTask and Callable, which is what this post covers.
Last time we talked broadly about why we need multiple threads. Now that we want to study concurrency, let's create threads ourselves and dig into its mysteries.
Hive's atomic data types support implicit conversion, similar to Java's type conversion. If an expression uses INT, for example, a TINYINT is automatically converted to INT — but Hive never converts in the reverse direction.
On April 6, Debian published a security update fixing a cross-site scripting vulnerability found in the Python HTML sanitizing library bleach. python-bleach is an allowlist-based Python library that sanitizes HTML text by escaping or stripping tags and attributes.
What's the relationship between high concurrency and multithreading? I never create threads in my code, so why does everyone start talking about multithreading the moment the subject comes up? My opening post digs into why we should learn multithreading, and how high concurrency turns into multithreading.
GitHub Actions is a free CI/CD service, and it's now being abused to mine cryptocurrency. I introduce what GitHub Actions is in another post, so I won't repeat it here — see "First look at GitHub Actions Workflows".
Last time we learned what Hive is. This post walks you through installing and deploying Hive so you can try this legendary data warehouse yourself.
