I don't like Karaoke, I prefer real music like Stratocaster or something like this. But this kind 'dream of music' so expensive in VN. I see that there are some Karaoke app provider like Kara. And I think it damn expensive for a device that combine of a PC and a monitor (touch screen). For my first (and fast) research Kara M10 cost about 6.5m VND for monitor, 11.5m VND for PC. I think this toy can be made much cheaper with something like arduino or raspi for PC, touch screen cost seem no way to reduce ? I don't know much about this but some laptop has touch screen and it is not so expensive. I have an occasion interview in Kara office and as many other 'Made in Vietnam' Electronic commodity, it is 'China inside'. It is a box like a small PC running Linux and opensource (moded) software I think. China now is hardware manufacturer of all the thing on Earth. So it is not surprise. I hate many scam and super bad quality, bad service of so many product i...

https://www.nayuki.io/page/understanding-facebook-ids On Facebook, an identifier (FBID) is assigned to most pieces of content. The identifier is a simple positive integer like 12345. You can use the FBID to cite a piece of content precisely and concisely using the URL fb.com/<fbid>. Explained below, a publicly visible FBID is available for many types of content, though not all types. These identifiers can be used (and abused) in interesting ways. Examples Here are some URLs of various content on Facebook. The FBID is indicated in bold: https://www.facebook.com/profile.php?id=4 https://www.facebook.com/pages/doorsopenTO/361063578336 https://www.facebook.com/photo.php?fbid=10151052362543337&set=a.402126878336.167300.361063578336 https://www.facebook.com/doorsopenTO/posts/10150868476418337 Scope For these top-level types, each item has an FBID: Person (a.k.a. profile, user, timeline) Page Event Group For these types that are attached to a top-level item, each ...

Refactoring của Martin Fowler đã ra bản 2 rồi nhưng bản 1 còn chưa đọc xong. https://refactoring.com/catalog/ Có nhiều kỹ thuật khá cool về kỹ thuật coding, refactor code, OOP ...

I have experienced a cool critical situation about lost live data. Lost live data is a common problems and myth. Outline: Bash ls order by time ls default order by name ls order by both time and name (fallback) Simulate time when create file Simulate time when move file (move is faster and may be timestamp duplicate) Bash programming variable as output of a command use cat /dev/urandom to generate random string, number ... /dev/urandom seem only return number when run inside bash shell (Windows Git-Bash) ... Our live server has been lost about 7000 images. Exactly its has been renamed, the original image file content is keep. But it's filename has been changed and inside Database it's not reflected yet. Let make it simple: In DB a record look like: ID   Image_URL ... 1     image_product_001.jpg In real image web data folder: name      vuETHeuteuehteecCHUE And the function that lead to disaster look like: loop through product...
