We’re pretty happy with SQLite and not urgently interested in a fancier DBMS

Every once in a while, someone suggests that beets should use a “real database.” I think this means storing music metadata in PostgreSQL or MySQL as an alternative to our current SQLite database. The idea is that a more complicated DBMS should be faster, especially for huge music libraries.

The pseudo-official position of the beets project is that supporting a new DBMS is probably not worth your time. If you’re interested in performance, please consider helping to optimize our database queries instead.

There are three reasons I’m unenthusiastic about alternative DBMSes: I’m skeptical that they will actually help performance; it’s a clear case of premature optimization; and SQLite is unbeatably convenient for desktop applications like beets.

Workload

Many people assume that Postgres or MySQL must be faster than SQLite. But performance depends on the workload, and SQLite is a great match for the beets workload.

Specifically, serious client–server DBMSes are great for web applications, where

Ethereum Debate Marred By Second Digital Currency Heist

Thursday’s new of a $50 million heist of digital currency at Ethereum. was followed today be reports of a second heist from the DAO, according to the Bitcoin News Service — this one for just 22 Ether. “It appears this is just someone who wanted to test the exploit and see if they could use it to their advantage… ” Slashdot reader Patrick O’Neill writes:
The currency’s community is currently debating a course forward for a currency who is built on the idea that it is governed by software and not human beings. One option is to fork the code, another is to do absolutely nothing at all.”

Vitalik Buterin, the co-founder of Ethereum, posted Sunday that “Over the last day with the community’s help we have crowdsourced a list of all of the major bugs with smart contracts on Ethereum so far, including both the DAO as well as various

An Open Letter (The DAO Attacker)

Pastebin PRO Accounts SPRING SPECIAL! For a limited time only get 40% discount on a LIFETIME PRO account! Offer Ends June 20th!

===== BEGIN SIGNED MESSAGE =====
To the DAO and the Ethereum community,

I have carefully examined the code of The DAO and decided to participate after finding the feature where splitting is rewarded with additional ether. I have made use of this feature and have rightfully claimed 3,641,694 ether, and would like to thank the DAO for this reward. It is my understanding that the DAO code contains this feature to promote decentralization and encourage the creation of “child DAOs”.

I am disappointed by those who are characterizing the use of this intentional feature as “theft”. I am making use of this explicitly coded feature as per the smart contract terms and my law firm has advised me that my action is fully compliant with United States criminal and tort law. For

Simple Contracts are Better Contracts: the Meltdown of the DAO

Simple Contracts are Better Contracts: What We Can Learn from the Meltdown of The DAO$50 million were “stolen” from a project called “The DAO” and now the Ethereum community is deciding how to move forward and recover from the disaster. But each crisis presents a learning opportunity, so let’s take a deeper dive into the matter and see how we can do better.First, though, here’s a primer on The DAO for those new to the subject.The DAOThe DAO is a digital pool of funds that is governed by code. Anyone can contribute funds to the pool to purchase voting power in it, and a quorum of shares is required to release funds to support select projects, just like with Kickstarter. This “group fund” was implemented on a digital currency platform called Ethereum and recently raised $150 million from hundreds to thousands of backers.Crisis with The DAOLast week, cryptocurrency security researchers

Delete Or Update All Adobe Flash Player Instances, Experts Warn

An anonymous reader quotes an article from BankInfoSecurity:
Security experts are once again warning enterprises to immediately update — or delete — all instances of the Adobe Flash Player they may have installed on any system in the wake of reports that a zero-day flaw in the web browser plug-in is being targeted by an advanced persistent threat group…. The bug exists in Adobe Flash Player 21.0.0.242 and earlier versions — running on Windows, Mac, Linux, and Chrome OS — and “successful exploitation could cause a crash and potentially allow an attacker to take control of the affected system.”

Thursday Adobe released an updated version of Flash patching 36 separate vulnerabilities, including the critical vulnerability which “if exploited would allow malicious native-code to execute, potentially without a user being aware.” While applauding Adobe’s quick response, researchers at Kaspersky Lab say it’s already been exploited in Russia, Nepal, South Korea, China, India, Kuwait
