Mengenal Git (Version Control Modern)

Saya baru mendapat tawaran dari seorang rekan untuk membuat sebuah project website dengan tujuan agar memiliki portfolio. seriusan, bikin website cuma ngejar portfolionya doang. Tapi ya saya terima aja, itung-itung buat pembelajaran juga. nah dia bilang karena kita ngerjain project ini dalam team, ada baiknya saya belajar dulu tentang git? apaan tuh git? nah inilah yang mau saya share, Cekidot.

GIT adalah sistem revisi kontrol dengan penekanan pada kecepatan.
yup itu dia... masih belum jelas kan?? oke, mungkin dengan penjelasan tentang "revisi kontrol" bisa bikin kita lebih faham.

Revisi kontrol, juga dikenal sebagai kontrol versi dan source kontrol(dan satu aspek dari manajemen konfigurasi perangkat lunak atau SCM), adalah manajemen perubahan pada dokumen, program , dan informasi lainnya dan disimpan sebagai file komputer . Hal ini paling umum digunakan dalam pengembangan perangkat lunak , di mana beberapa orang dalam tim mungkin mengubah file yang sama. Perubahan biasanya diidentifikasi dengan nomor atau huruf kode, disebut sebagai "nomor revisi", "revisi tingkat", atau hanya "revisi". Sebagai contoh, sebuah set awal file adalah "revisi 1". Ketika perubahan pertama dibuat, set yang dihasilkan adalah "revisi 2", dan seterusnya. Setiap revisi terkait dengan timestamp dan orang yang membuat perubahan. Revisi dapat dibandingkan, dipulihkan, dan dengan beberapa jenis file, digabungkan.

Versi Control System (VCS - VCS tunggal) yang paling umum dijalankan sebagai aplikasi yang berdiri sendiri, tetapi kontrol revisi juga tertanam dalam berbagai jenis perangkat lunak seperti pengolah kata (misalnya, Microsoft Word , OpenOffice.org Writer , KWord , Halaman , dll ) spreadsheet (misalnya, Microsoft Excel , OpenOffice.org Calc , KSpread , Bilangan , dll),  dan dalam berbagai sistem manajemen konten (misalnya, Drupal , Joomla , Wordpress ) Integrated Revision Control adalah fitur utama dari wiki software(software wikipedia) paket seperti MediaWiki , DokuWiki , TWiki dll Di wiki , kontrol revisi memungkinkan kemampuan untuk mengembalikan halaman ke revisi sebelumnya, yang penting untuk memungkinkan editor untuk melacak setiap suntingan yang lain, kesalahan yang benar, dan membela wiki publik terhadap vandalisme dan spam.

Software tools for revision control sangat penting untuk Proyek yang dikembangkan oleh lebih dari satu developer.

Membuat Teks Dalam String Menjadi Title Case di PHP

Kasus : 
saya ingin membuat String didalam Variable php yang saya punya menjadi title case (huruf besar disetiap awal kata), dengan catatan setiap kata seperti "dan", "tapi", "yang", "adalah" tetap diawali dengan huruf kecil. bagaimana caranya??

Pemecahan :
saya membuat sebuah file yang berisi function untuk menggenerate kata-kata dalam sebuah variable menjadi title case. kita hanya perlu memasukkan variable yang berisi teks kedalam parameter dalam function.
Anda bisa Mendownload filenya disini

didalamnya terdapat 2 file,
file yang bernama convert_titlecase.php adalah file berisi function converternya,
dan file yang kedua bernama instansiasi.php adalah contoh penggunaannya.

sebagai catatan, didalam file convert_titlecase.php ada script yang kurang lebih seperti ini :

$smallwordsarray = array( 'di','dan','atau','tetapi','tapi','adalah','jika','kemudian','yang'); 

ini adalah array yang berisi data kata-kata yang huruf awalnya tidak akan dikapitalkan,
contoh, saya memiliki kalimat "ini adalah kata yang akan di konversi menjadi title case" ketika di konversi akan menghasilkan kalimat "Ini adalah Kata yang Akan di Konversi Menjadi Title Case"

kata "adalah", "yang", "di" huruf awalnya tidak menjadi kapital karena ada didalam data array $smallwordsarray, dan anda bisa menambah atau mengurangi data dalam arraynya.



jika anda mengalami kesulitan untuk mendownload filenya, berikut saya tuliskan script phpnya
 file convert_titlecase.php

<?php

class Stringtotitlecase
{
    function strtotitle($title) // Konversi $title ke Title Case, Dan Me-return hasil.
    {
        //  array 'small words' adalah data array yang berisi kata - kata
        //  yang huruf awalnya tidak menjadi kapital
        //  anda bisa menambahkan atau mengurangi sesuai kebutuhan anda
        $smallwordsarray = array( 'di', 'dan', 'atau', 'tetapi', 'tapi', 'adalah', 'jika', 'kemudian', 'selain', 'ketika', 'dari', 'oleh', 'untuk', 'ke', 'yang' );
        // memisahkan isi string menjadi kata-kata
        $words = explode(' ', $title);
        foreach ($words as $key => $word){
            // jika Ini kata pertama, atau bukan bagian dari $smallwordsarray,
            // Kapitalkan huruf awalnya dengan ucwords().
            if ($key == 0 or !in_array($word, $smallwordsarray)) $words[$key] = ucwords($word); }
            // Menggabungkan kembali kata-kata kedalam string baru
            $newtitle = implode(' ', $words);
            return $newtitle;
    }
}
?>

 file instansiasi.php

How Much Do You Know About the Mystery of Data Recovery Technology?

lost your data
It is suggested to talk collectively together with your close friends and inquire concerning the principal factors of some reputable company. However believe that a hybrid brick approach is the best from the standpoint of overall system reliability.
Not software will like database which it needs to face so bad environment. You need to consider every possible mistake and fault, for example, the system is powered damaged disk, or even earthquake fire. And your target is very clear: no matter what happen fault, data can be lost, you may feel this some make a mountain out of a molehill, but to many business applications, such as Banks, the train ticket system, etc.), it is simply the most basic requirements.
Your damages or lost information ought to get essential to them as it's to you. with low level recovery mechanisms built into the unit. Not completely. In some ways flash makes the problem worse because of the technology's intrinsic write reliability problems. On the plus side, the speed of recovery of SSD and flash is significantly faster so you can recover much quicker than with spinning disk. It is not invariably how the information get deleted, but rather there may be the case, when these may be corrupted. Information recovery software program can fix the file, that could be accessed later.
Data backup is easily one of the most critical elements of a complete disaster recovery plan. Data can be simply retrieved from just about any hard disk. In planning for disaster recovery, should consider five important questions: Understanding what data is mission-critical may just save your business in a disaster. which will help you control data storage costs. If you have experienced data loss due to any of the reason, you need for data recovery to recover your valuable data. For example, a 2009 study by MetaGroup cited that just 6% of businesses survive catastrophic data loss. Even better, choose a company that will manage your data recovery for you, lifting that burden from your shoulders.
The essence of the recovery is data redundancy, in many of the redundancy means, log (log) may be the most commonly used technology (though we still have many other options, such as shadow page, etc.). Before the database modification, the system will change the image data before (the) and you want to modify data images saved in the log. In the process, there are two points need to be guaranteed. One is the log must prior to its corresponding modification is written into the database, we call this first writing blog (WAL) agreement, it's easy to understand, imagine if modified by writing to a first, and the system in the log is written to before the crash, it will not be able to put this transaction recovery to the start of the state. Second, before the affairs submission, must log written to the database. Otherwise, the system can't guarantee the follow-up of fault not lost the affairs of modifications. We will not be able to achieve our users in front of the commitments. For example, if we want to recovery the photo from memory card, we often use the photo recovery for Mac Software is compatible with Memory Sticks, Smart Media, Micro Drives, SD Cards, xD Cards, PCMCIA, Floppy Disks, etc. Simply insert your Digital Film into the reader and run Photo Recovery for Mac on the media
Even data saved on the hard disk that's no more recognized through the PC's Bios can from time to time be retrieved using software programs alone. or people and companies who store their most necessary and valued info on their machines and servers, copying isn't just a great plan, it's important, Inch he described. What systems and information are absolutely critical to running your business day-to-day? Emails? Accounting data? Customer records? All of the above? Then you should use data recovery software to recover and restore your data. If your city were flooded, tapes stored at your office or even elsewhere in your same city might prove worthless.
data recovery
For seriously broken drives this is often an costly process, but customers very frequently give on valuable data that's far simpler and fewer costly to revive. "The requirement for copying your computer data is booming every single day. A 2007 MetaGroup study found that only 3% of data losses occur due to natural disasters; fortunately, the preparation for both types of disasters is much the same. Evaluating the importance of your data will help determine what needs to be quickly accessible and what isn't as critical, You should be aware of these things to avoid your data from loss. These are the five common reasons of data loss (Hardware Failure, Firmware Corruption, Logical Error, Accidental Deletion, and Operating System failure). If your data is lost due to the software problem like logical error, operating system corruption or accidental deletion, But customers very frequently give on valuable data that's far simpler and fewer costly to revive, Inch he described.
He stated that almost everyone has experienced the dread of understanding that important, valued or personal data has disappeared and was adamant that taking safeguards to safeguard security making backup copies might make recovery simpler. 97% are due to mechanical failure or human error, both of which are far more common. There are two options of data recovery you have- one is software method and second is hardware. Lots of people are in possession of large collections of information, including personal photos, "Given a proven method, data can be simply retrieved from just about any hard disk. For seriously broken drives this is often an costly process, Speaking of Mac, most of people must be very familiar with it since it has been widely used nowadays. Do you have a Mac computer in hand? Are you confusing how to recover lost data on Mac? Here I'd like to recommend you some free Data Recovery for Mac apps to assist you recover your lost data on the Mac computer. It can recover Mac data from Macintosh hard drive, iPod, USB drive, SD card, digital camera, mobile phone, MP3, and MP4 player. Compatible with HFS+, and FAT file system, this non-destructive hard drive recovery Mac software ensures safe Mac file recovery without modifying the original data saved on your Mac machine or any other storage media. If you don't trust in these freeware, you can just turn for help to an affordable and cost-effective Data Recovery Software for Mac. Here let's go ahead to see the free Data Recovery for Mac right now!
Music libraries and e-books saved on their own products' assets that may be costly or impossible to exchange carrying out a hard disk failure. Data should be backed up in multiple locations, including somewhere out of the area. The best bet for many business owners is a solution that allows you to back up your encrypted data via the cloud, safely, to locations off-site and out of the area. In a natural disaster, your key personnel may be wearing several hats. Have a specific person designated for data recovery.
Moreover, the firm ought to get capable sufficient to recover information and facts from entirely unique safe-keeping mediums. This in essence becomes one large logical device that is able to protect data far more effectively and at much lower cost. This software program can facilitate your in recovering information and facts that are lost attributed substantial exhausting generate injury or basic pc error or deletion of information accidentally. The main findings of the research meeting are that the unit of failure should not be a disk drive; rather it should be a group of devices with embedded intelligence (i.e. a 'brick'); This can be overcome with techniques like wear leveling but component failures are a random problem and so the probability of multiple failures is still high. So in theory, a hybrid solution where flash or SSD is the recovery mechanism could help quite significantly.
