• Chrome 33 shows ugly, blocky, pixelated fonts in Linux

  - by Andrew Mao

  After updating to the latest version of Chrome (33) on my Gentoo Linux box, certain sites such as GitHub have started rendering with ugly, pixelated, non-antialiased fonts. Small text is now basically impossible to read. Before this, GitHub had looked the same to me on Windows, Linux, and Mac computers. So what has happened here and how can it be fixed? EDIT: Appears to be fixed on the stable release of Chrome 34.

• Nginx Redirection Issue

  - by James Gu

  My Nginx setting currently has this: location / { if (!-e $request_filename){ rewrite ^/(.*)$ https://domain.com/index.php?id=$1 redirect; } } Basically for non-existing pages (404) it redirects user to the home page. But now I have a wordpress blog setup at https://domain.com/blog/, but any wordpress items eg. https://domain.com/blog/test also got redirected to the home page. I wonder how to fix this?

• Fixed width, free, sans serif fonts

  - by The Journeyman geek

  I'm a dyslexic and i generally use arial for most things, since its probably the most readable font for me. However i'd like to have a fixed width font with similar charecteristics (sans serif, distinct, 'simple' characters etc) since some things break with non fixed width fonts, but at the same time, most of the 'standard' fonts are harder to read for me- any suggestions?

• JavaScript-based applications and text browsers

  - by Vi

  How to use complex AJAX applications with a lot of menus and with X.509 authentications in non-GUI mode with simple browsers? For example, I can login to Webmoney from console using links/lynx/link2 (but not w3m), entering captcha (using aaxine) and do operations there, but can't login not using X.509 certificate (even if I try to separate SSL part using "socat tcp-l:... openssl:...:443,cert=extracted_from_firefox.pem") Is there some program that behaves like fully-fledged browser (build DOM/execute JS/Support all features except of actually displaying things), but without GUI and dependencies on GUI libraries?

• Addons which actually make Firefox run faster?

  - by Zombies

  I would like to know of addons which actually enhance firefox's performance, both intentionally and unintentionally. I find that firefox tends to have major performance issues with certain websites. These websites tend to have a fair amount of javascript and css, and probably a large dom tree which may even be growing dynamically through javascript too. The worse offenders are those with heavy javascript, use heavy facebook integration, websites with non performant javascript, excessive javascript and websites with too many advertisements.

  I have an application installed in my RHEL6 box that has a GUI (AppGui.sh). My problem is that a few non-tech users would like to access this GUI remotely.

What facilities/utilities exist to alert me to non-successful conditions.

  I will admit that I am new to the tech/dev field. It seems to become a trend that every time I have to work with pdfs a part of me dies. Why is this format as ubiquitous as it seems to be? Is it just non-tech people that prefer pdfs?

• Pushing DNSSEC updates with offline keys

  - by eggyal

  In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

• Should I worry about making my picasa web albums public?

  - by Motti

  I choose the public option for all my albums in Picasaweb, these mostly (90%) contain pictures of my children which I share with my family. Ever so often somebody I don't know adds me as a favorite, at current count I have 7 people in my fan list (non of whom I know) and only three of them have any public albums. Is this creepy? I take care not to upload any pictures that may attract perverts What would you recommend, private by default or continue with public?

• On an SVN repository, can you ignore all extensions except one?

  Our need is to store only axcrypted (.AXX) documents in an SVN repository, and we want to prevent accidental uploading of the non-encrypted documents. Is there a way to do this on SVN server? We would like to enforce this .AXX only policy on server-side of the SVN, so we don't have to rely on the ignore list of all our SVN clients.

• Different DPI on MacBook Pro and external monitors - what options are there?

  - by Ollie G

  I have an external monitor connected to my MacBook Pro, the two screens have different DPIs. Ideally I would like them to be the same, but as this is not the case, the best option I can see is reducing the resolution of the MBP screen to bring its DPI as close as possible to the external monitor. This introduces scaling artefacts on the screen, as LCDs don't look good at non-native resolutions. Is there a standard or best way of handling this, and if not, what other options are available?
