...ten to the file. The grep filters the standard output (you can decide how selective you want it to be, and may have to change the spelling depending on locale and O/S) and the final >&2 means that the surviving error messages (written to standard output) go to standard error once more. The f...

...iving an Intent(message) that was sent to your app in general. To increase selectivity on what type of intents your fragment can receive you can use an intent filter as in the example below. An advantage of this approach is that the Intent(message) can be sent from everywhere whithin your app(a d...

...d 2 aren't used? How is the current ring determined? The current ring is selected by a combination of: global descriptor table: a in-memory table of GDT entries, and each entry has a field Privl which encodes the ring. The LGDT instruction sets the address to the current descriptor table. See ...

...7 | white | | 39 | 49 | default | +~~~~~~+~~~~~~+~~~~~~~~~~~+ Select Graphic Rendition (SGR) SGR just allows you to change the text. Many of these do not work in certain terminals, so use these sparingly in production-level projects. However, they can be useful for making program outpu...

...y are already familiar with regexes. It's a huge mistake, use xpath or css selectors to navigate html and only use regular expressions to extract data from actual text inside an html node. This might already be obvious to you, it becomes obvious quickly if you try it but a lot of people waste a lot ...

...Now, what you do is you have the 50 in different places - your SQL script (SELECT TOP 50 * FROM orders), your Website (Your Last 50 Orders), your order login (for (i = 0; i < 50; i++)) and possibly many other places. Now, what happens when someone decides to change 50 to 25? or 75? or 153? You n...

...port is quite good, though: it supports detecting endianess from a BOM, or selecting it explicitly in code. It also supports producing output with and without a BOM. There are some more interesting conversion possibilities absent. There is no way to deserialize from an UTF-16 byte stream or string ...

...ilable: isShut==false && isLocked==true. Because the types I have selected as my representation admit this state, I must expend mental effort to ensure that the class never gets into this state (perhaps by explicitly coding an invariant). In contrast, if I were using a language with algebr...
