MySQL InnoDB

前幾天就有不少媒體報導 買下來,我只是覺得 這家公司好像很熟,可是幹嘛跟 做比較 XD (其實我沒有仔細看,前幾天忙跳槽的事情,很多東西看個標題而已...)

直到看了 這篇 Oracle buys Innobase. MySQL between rock and hard place? 後,我才突然把 與 MySQL InnoDB 的關連想起來 XD

然後我才馬上理解 買走之後對 的影響... row-level locking + transaction 啊~~~

Google BigTable

Google's BigTable 得知 Jeff Dean 將在 10/18 在 講 BigTable:

BigTable is a system for storing and managing very large amounts of structured data. The system is designed to manage several petabytes of data distributed across thousands of machines, with very high update and read request rates coming from thousands of simultaneous clients. In this talk, Jeff will discuss the basic design of BigTable and its implementation, provide some performance measurements, and outline some current applications of the system. He'll also touch on Google's future goals and directions for the system.

屆時在 Colloquium and Televised Talk Information 也可以看到轉播。

Web-based Applications

上面這篇 The Web-based Office will have its day 列出了一張表,顯示了有一卡車的廠商與社群不斷嘗試透過瀏覽器建立 Web-based Applications。(Early AJAX Office Applications)

裡面有以前就一直被大家注意的 (用的人也蠻多的) 、常常被拿出來當作 示範的 、前幾天才出現的 ,當然,還有帶動 風潮的

OpenSSH 與 SSH Communications 的 SSH

的報導, (當初發展 SSH Protocol 的公司) 認為 的品質不足以成為企業級的產品:(SSH Claims Draw Open Source Ire)

OpenSSH is not an enterprise-class product that is needed for the demands of a large-scale deployment. We do not compare OpenSSH to our SSH Tectia solution, since it's far from the same,

可是 的佔有率遠遠超越其他人 XD

However, OpenSSH is very popular and is commonly deployed in almost all BSD, Unix and Linux systems. More than 87 percent of Internet-facing servers were using OpenSSH, according to an OpenSSH Internet scan in September 2004.

這段 Comment 直接說明了 的氣量:

They claimed OpenSSH was not "enterprise ready". Pointing out that many, many enterprises not only use it, but build it into their products is a fairly compelling rebuttal.

They are either using their own private definition of "enterprise" that doesn't include organisations like Cisco, or they are lying. Either way, they are discredited.

MySQL 5.0

5.0「餅乾版」釋出 (我很喜歡這個詞,可是我忘記是誰開始用的):MySQL 5.0 Candidate ReleasedMySQL 5.0 Release Candidate Available. Win an iPod nano!

5.0 在某些機器上已經跑了一陣子 (當初是為了 VIEW 的功能使用 5.0),用了幾個月下來還算蠻穩定的。(如果不會用到奇怪的功能...)

Update 在他的 blog 上介紹了一下 5.0:MySQL 5.0 Release Candidate Available

7-Zip Security Issue

在 Windows 下我一直都用 ,常看到的格式都可以解 (對我來說,能解 zip、rar 兩種最常看到的格式就好了),另外一個重要的原因是 Open Source () & Free (at price)。

剛剛在 看到 的 Security Advisory:7-Zip ARJ Archive Handling Client-Side Buffer Overflow Vulnerability,指出了 處理 ARJ 壓縮格式的部分有安全性問題...

手上還沒更新到 4.27 beta 的更新一下吧 :p
