一些懷古的點陣字型

前幾天在 Hacker News 上看到的懷古字型:「The Ultimate Oldschool PC Font Pack」,在「FONT INDEX」這頁裡面有很多字型的圖片可以看。

比較有趣的是在「README」這頁提到的版權問題,點陣字體在美國是無法被版權化的:

Q. Is this even legal? The original fonts are not yours. Do you have the right to distribute these versions?

A. Short answer: as far as I was able to research, there is nothing illegal or infringing about this collection. The raw bitmap typefaces are not copyrightable, unlike fonts in specific formats such as .fon and TrueType (which qualify as software); at least this is the case in the US, where this site is based. For a longer and far more boring answer, see the legal stuff section below.

這點可以在維基百科上的「Intellectual property protection of typefaces」這篇看到對應的說明:

Typefaces cannot be protected by copyright in the United States (Code of Federal Regulations, Ch 37, Sec. 202.1(e); Eltra Corp. vs. Ringer). The idea that typefaces (rather than fonts, which are computer software) cannot be copyrighted in the United States is black letter law. 37 C.F.R. § 202.1(e). Under U.S. law, typefaces and their letter forms or glyphs are considered utilitarian objects whose public utility outweighs any private interest in protecting their creative elements. However, there is a distinction between a font and a typeface. The machine code used to display a stylized typeface (called a font) is protectable as copyright. In 1992, the US Copyright Office determined that digital outline fonts had elements that could be protected as software. Since that time, the Office has accepted registration of copyright for digital vector fonts, such as PostScript Type 1, TrueType, and OpenType format files.

有不少字型有提供 8x16 的大小,看起來之後還是可以找機會用看看?應該有機會搭 16px 的中文字...

組一台 RISC-V 的 PC

RISC-V 是目前最有名的 open source 指令集,但似乎不太好找對應的硬體... 在「Building a RISC-V PC」這篇則是介紹了怎麼弄一台 RISC-V 的 PC:

採用的硬體是 HiFive Unleashed (USD$999),硬體架構包括了:

  • SiFive Freedom U540 SoC
  • 8 GB DDR4 with ECC
  • Gigabit Ethernet port
  • 32 MB quad SPI flash from ISSI
  • microSD card for removable storage
  • FMC connector for future expansion

沒有 USB 與 HDMI,作者是透過 HiFive Unleashed Expansion Board (USD$1999) 接出來的,不過這張還包括了 FPGA,這好像有點超過,兩個套件再加上 M.2 或是 SATA 的 disk 應該是超過台幣十萬...

不過畢竟算是早期的產品,之後有規模後應該會開始有中低價位的產品出現...

用 ESP8266 模擬 PC-XT...

看到拿 ESP8266 模擬 PC-XT,是個懷古時間:「IBM PC-XT Emulator on an ESP8266」。

現在小板子的 CPU 跟記憶體都比三十年前的桌機還要大了,直接在上面跑模擬器就算慢一點也已經不是問題了... 直接上麵包板接起來跑:

然後也可以跑 Windows 3.0:

純粹 hacking 的專案 XD

在 PC 的 Google Chrome 裡跑 Android 應用程式

OSNews 上看到可以在桌機上用 Google ChromeAndroid 應用程式:「Run Android apps on a PC with Google Chrome」,引用的報導是「You can now run Android apps on a Mac or PC with Google Chrome」這篇。

參考「Getting Started with ARC」這篇文章,裝「ARC Welder」這個...

看起來 Linux 也能跑,有空來測試看看... O_O

微軟提供的 IE{7,8,9,10} 測試環境...

微軟前幾天公開了 IE{7,8,9,10} 測試服務:「Testing made easier in Internet Explorer」。

測試服務包括:

  • 網站版本,可以測試公開網站。
  • 虛擬機版本,可以測試內部網站。這次除了提供 Virtual PCHyper-V 版本的映像檔外,還提供了 VMware PlayerVirtualBox 版本。

不過這些檔案會不會太大了點... 我是抓 VirtualBox 版本,IE10_Win8.zip 居然有 2.7GB,為了真實模擬,所以把整個 Win8 包進去嗎 XDDD
