Chapter 1: Introduction 1 1 Introduction ne is a full screen text editor for UN*X (or, more precisely, for POSIX: see Chapter 7 [Motivations and Design], page 65). I came to the decision to write such an editor after getting completely sick of vi, both from a feature and user interface point of view. I needed an editor that I could use through a telnet connection or a phone line and that wouldn’t fire off a full-blown LITHP1 operating system just to do some editing. A concise overview of the main features follows: • three user interfaces: control keystrokes, command line, and menus; keystrokes and menus are completely configurable; • syntax highlighting; • full support for UTF-8 files, including multiple-column characters; • 64-bit

  • 802.11N Support in Freebsd (For the Run(4) Driver)
    802.11n support in FreeBSD (for the run(4) driver) 15412 F’19 1 / 15 Motivation ● “Do something with operating systems” – OS Junkie: Ubuntu → Fedora → Arch Linux → Gentoo → FreeBSD ● Do something for the community – So much free (not free as in free beer) software out there for use – Time to give something back! ● Faster WiFi doesn’t hurt – Makes FreeBSD more usable ● Less angry users: “But this works on Lunix!” 2 / 15 FreeBSD ● Open source, UNIX ● Official webpage: freebsd.org ● Large, helpful community – IRC Channels on Freenode (#freebsd) – Forums (forums.freebsd.org) – Mailing lists (lists.freebsd.org) ● Latest Release: FreeBSD 12 (2018) 3 / 15 802.11 ● IEEE 802.11: Standard for WiFi – 802.11b: 2.4GHz, Max rate 11 Mbps, range 150 ft., Year 1999 – 802.11g: 2.4 GHz, Max rate 54 Mbps, range 150 ft., Year 2003 – 802.11n: 2.4GHz or 5 GHz, Max rate 300 Mbps (single antenna), 450 Mbps (MIMO), range 175 ft., Year 2009 4 / 15 Ralink ● Produces WiFi chips – See https://wikidevi.com/wiki/Ralink for list of chips ● Linux driver: rt2800usb (USB Ralink 802.11n devices) ( https://wiki.debian.org/rt2800usb). ● FreeBSD driver: run (see https://www.freebsd.org/cgi/man.cgi?run(4) ) – Caveats : “The run driver does not support any of the 802.11n capabilities offered by the RT2800, RT3000 and RT3900 chipsets.“ 5 / 15 Existing code base ● The run driver supports several chipsets and adapters (such as ASUS USB N-66) but without support for 802.11n – This means reduced speeds – This means it will misbehave when you turn on your microwave ● run(4) also has annoying ‘device timeout’ errors where the card stops responding.

  • Factor — Factor Analysis
    Title stata.com factor — Factor analysis Description Quick start Menu Syntax Options for factor and factormat Options unique to factormat Remarks and examples Stored results Methods and formulas References Also see Description factor and factormat perform a factor analysis of a correlation matrix. The commands produce principal factor, iterated principal factor, principal-component factor, and maximum-likelihood factor analyses. factor and factormat display the eigenvalues of the correlation matrix, the factor loadings, and the uniqueness of the variables. factor expects data in the form of variables, allows weights, and can be run for subgroups. factormat is for use with a correlation or covariance matrix. Quick start Principal-factor analysis using variables v1 to v5 factor v1 v2 v3 v4 v5 As above, but retain at most 3 factors factor v1-v5, factors(3) Principal-component factor analysis using variables v1 to v5 factor v1-v5, pcf Maximum-likelihood factor analysis factor v1-v5, ml As above, but perform 50 maximizations with different starting values factor v1-v5, ml protect(50) As above, but set the seed for reproducibility factor v1-v5, ml protect(50) seed(349285) Principal-factor analysis based on a correlation matrix cmat with a sample size of 800 factormat cmat, n(800) As above, retain only factors with eigenvalues greater than or equal to 1 factormat cmat, n(800) mineigen(1) Menu factor Statistics > Multivariate analysis > Factor and principal component analysis > Factor analysis factormat Statistics > Multivariate analysis > Factor and principal component analysis > Factor analysis of a correlation matrix 1 2 factor — Factor analysis Syntax Factor analysis of data factor varlist if in weight , method options Factor analysis of a correlation matrix factormat matname, n(#) method options factormat options matname is a square Stata matrix or a vector containing the rowwise upper or lower triangle of the correlation or covariance matrix.
