Please provide an option to increase the font size in the Android app.
I'm using the alpha version of the android app on the first generation nexus 7 tablet.  The font size is a little bit small for my liking and I'm not able to pinch zoom to increase the font size.  Is this a feature that is planned in the release?
Reinstalling Windows 10 - how many digital licenses I have linked to my account I need to reinstall Win 10 (after virus). After reading online, it looks like I would be able to do it easily since my system is activated with digital license.   However, I have a question. I have at least 3 PCs in my house with the same Microsoft account on them. Presumably, all of them have digital license linked to this same Microsoft account. I wonder if there is a centralized place to check all my digital licensed connected to my Microsoft account? ICANN charges 18¢ per domain name registered regardless of its extension, but I pay $10 for a domain name per year with my registrar.   What do domain name registrars do for its customers to justify this extra $9.82?  Is there something that they do for our domain names other than registering it with ICANN?   I just read about the 7 people who hold the ICANN database key and got a little bit curious to know what the domain name servers do for us to justify this extra amount (12 times the actual fee)? String comparison in Python: is vs. == So there are several types of transistors:   BJT JFET MOSFET   Combine all that with the various flavors of each (NPN, PNP, enhancement mode, depletion mode, HEXFET, etc) and you've got a wide array of parts, many of which are capable of accomplishing the same job.  Which type is best suited for which application?  Transistors are used as amplifiers, digital logic switches, variable resistors, power supply switches, path isolation, and the list goes on.  How do I know which type is best suited for which application?  I'm sure there are cases where one is more ideally suited than another.  I admit that there is some amount of subjectivity/overlap here, but I'm certain that there is a general consensus about which category of applications each of the transistor types listed (and those I left off) is best suited for? For example, BJTs are often used for analog transistor amplifiers and MOSFETs are generally used for digital switching.  PS - If this needs to be a Wiki, that's fine if someone would like to convert it for me From the third week ( when does it actually begin) This describes a certain natural process that takes 15 weeks  It describes what a certain component looks like at some point in time during a naturallly occurring process  What I don't get is if it means it appears this way starting in the third week or after ?

I can see it with:  # find /var/www/html -maxdepth 1 -type d   which gives me:  /var/www/html /var/www/html/files /var/www/html/.?   unfortunately the question mark there is not the actual character ?, it merely seems to denote that there is no proper glyph and/or translation for that character. So something like rmdir is out of the question. My system has UTF-8 as the default locale as so many modern Ubuntu systems, but admittedly the folder in question may have originated on a RHEL or CentOS box (tared up and unpacked).  # env|grep LANG LANG=en_US.UTF-8   When trying to cd .\? (as mentioned before it is not actually ?) I get auto-corrected to . by bash and actually end up in /var/www/html/. for some reason. Now if I can't "name" this folder usefully, I cannot access it in any way. How can I get rid of it without putting the whole system in jeopardy?  Now I installed detox already but that only seems to act on files, not folders, according to its documentation and besides it still requires that I be able to name the object somehow to do something with it. I am a new user for Ubuntu. I downloaded 13.10 yesterday and made a bootable USB with universal USB installer on my Lenovo IdeaPad Z580 laptop which is now using UEFI; everything appeared OK.

Improved Help Center - site-specific pages and site-specific edits to all pages Right now, moderators can edit some pages in a site's Help Center. For example, the entire /help/on-topic page can be edited. However, the /help/dont-ask page can't be edited at all.  I'd like to see two changes to the Help Center:   All pages should be editable by site moderators. Some pages do apply to all sites, such as the /help/dont-ask page I mentioned above. However, it may be useful to edit in some site-specific guidance. The entire page doesn't need to be editable in order to ensure that key commonalities across the network remain in place on all sites. This uneditable content should be at the top of the page and moderators should be able to add site-specific content to the bottom. Moderators should be able to add new pages. Instead of maintaining meta tag [faq], FAQs can be added right into the Help Center from Meta. The Help Center serves as a single point of reference for the community rules, norms, and policies. Meta questions can be used to discuss updates to pages. This avoids issues such as question and answer ownership and the ability to accept/change accepted answers as users come and go from a site. An active site will always have diamond moderators to perform the edits to the Help Center.   Note that site-specific pages do already exist. , which no other sites have. This is something relevant to Stack Overflow (and perhaps a few other sites). It would be nice to allow sites that have this policy to link to their own Help Center for it and to edit the page to provide additional examples that may be relevant to their user base.
