After I clicked the "start a bounty" link, in the drop down list, the 50 reputation option did not exist:
It's possible to offer and award bounties of reputation on questions.   What is a bounty? How can I find questions that have a bounty attached? How do I start a bounty? When can I start a bounty? Why is the system requiring me to choose a bounty amount that's higher than the minimum? Can I use Markdown formatting in the bounty remarks? Can I edit the remark? How long is the bounty period? How do I award a bounty? Can I award a bounty to my own answer? Can I award a bounty to an old answer? If I offer a bounty on someone else's question, can I award the bounty to their answer? After awarding the bounty, can I remove it or move it to another answer at a later time? What happens if there's no answer after the bounty period? What happens if I feel my question is still unanswered? What is automatic awarding? Are bounty awards exempt from the 200 points/day reputation limit? How does Community Wiki mode affect bounties? How does user deletion or post dissociation affect bounties? Can I award a bounty to an answer from a deleted user or one where the author was dissociated? Can I offer a second bounty after the first one has expired? Can I raise my bounty? What happens if a bounty question is closed or deleted? Why can't I vote to close or migrate a bounty question? What happens if I delete my account while I have an active bounty? Do I keep an awarded bounty when I delete my answer? What happens if a question where I awarded a bounty later gets deleted or migrated? Can I cancel my bounty? Can I affect / divide / share part of my bounty to two (or more) users? How many outstanding bounties can a single user have?      See also:  in the Help Center
How do I bypass "this connection is not private" warnings in safari? How to load JAR files dynamically at Runtime? Why is it so hard to do this in Java? If you want to have any kind of module system you need to be able to load JAR files dynamically. I'm told there's a way of doing it by writing your own ClassLoader, but that's a lot of work for something that should (in my mind at least) be as easy as calling a method with a JAR file as its argument.  Any suggestions for simple code that does this? Database schema documentation for the public data dump and SEDE Stack Exchange releases "data dumps" of all its publicly available content roughly every three months , and also makes that information queryable over the Internet at the  (SEDE) (updated weekly, on Sunday). Over time, as new features and other bits of data are introduced to Stack Exchange sites, the "anatomy" of the data dump is likely to change. Proof of matrix norm property: submultiplicativity Series prove or disprove statement Let $a_n$ be a sequence. $\lim_{n\to\infty} a_n =0 $ then the series: $\sum_{n=1}^\infty a_n, \ \sum_{n=1}^\infty (a_n+a_{n+1}) $ converge and diverge together.  It doesn't seem right, there are no convergence tests that fit this question yet every counterexample I try does not seem to work. Is this how I should see the sum? $\sum_{n=1}^\infty (a_n+a_{n+1})=2\sum_{n=1}^\infty a_n +a_{n+1}$ If so then there's no real difference between the two series since you multiply it by a constant and add just one more value. Attempting to create a tag wiki when a user has hit the suggested edit limit should alert the user that no more edits can be suggested at this time I ran into an issue on Gaming.SE where I attempted to create a tag wiki and wiki excerpt for a tag which did not have one already while I already have the maximum of five suggested edits in the queue.  Navigating to the tag page for the  provides a link to  for this tag. This link redirects to the  for this tag, without telling me that I can't submit an edit because I've reached the maximum number of suggested edits. Instead of silently redirecting, the page should alert me that I can't suggest any more edits until my suggestions are reviewed. Is QImage able to open and render pure 16-bit images? When we lie down, the "back part of the body" is in contact with the bed. It includes the heels, the calves, the backside, the back, and the back of the neck, and the back of the head etc.  How do we refer to the entire "back part" of the body? Is there a good casual online place to practice/learn bridge? I know that Pogo.com (which powers Yahoo Games) has a long running online bridge game and that there are a handful of places for serious tournament/MasterPoint level bridge players online (though most seem based on software written a decade or more ago) but are there any places to play, practice and learn bridge in a more casual manner? Ideally via a well designed modern piece of software? How can I repair grub? (How to get Ubuntu back after installing Windows?) I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back? E: dpkg was interrupted... run 'sudo dpkg --configure -a' I was running an upgrade with the apt-get command, and it was taking an exceptionally long time because half way through my ISP hit me in the face with their fair usage policy.   After sitting outside &amp; watching the rain for awhile my electronics regained consciousness, so I went back to complete the upgrade and my terminal scolds me with   "E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem."   The last bit of legible info was all this:  Installing (ri/RDoc) documention for (stuff and such) ERROR:  Could not find a valid gem 'watobo-0.9.8.724.gem' (&gt;= 0) in any repository rm: cannot remove `watobo-0.9.8.724.gem': No such file or directory  Setting up metasploit (4.3.0-bt1) ...

All up until:  A    lib/gemcache/ruby/1.9.1/gems/state_machine-1.1.2/gemfiles/active_record-2.1.2.gemfile.lock   ...and there it has sat, all night.    If I stop it, will I still get the dpkg error (on the off chance that I won't), or if so what do I need to to resume using apt-get commands and its Super Cow Powers? Are common cryptographic hashes bijective when hashing a single block of the same size as the output? I am trying to buy a laptop, and I have seen in many place that they show GDDR3 and sometimes  DDR3. What is the difference between them?  afaik DDR3 is a type of RAM used for system memory, while GDDR3 is a type of RAM used for graphics cards. So does "G" only stand for Graphics or does it have another particular meaning?

Top bar search doesn't pick up subdomains I wanted to switch to  in the handy dandy site switcher in the new top bar. Entering "cook" brings up nothing:     ... so I have to remember that the boutique title of the site is "Seasoned Advice":     ... in which case the site switcher also thinks that maybe I was thinking of heading over to  to see what's up. So the site switcher searches site names and descriptions, but not subdomains. This is unexpected behavior - I believe it should search all three. Create a workflow rule when Lead status is changed from X to Y I want to create a workflow rule which should be triggered when I change the Lead Status value from 'Open: Not Contacted' to 'Open: Working'  Any help with this please? My organization is looking at developing mobile applications, we have a wealth of web development resources. There are many factors to consider in making the decision of how to develop this application such as Cost(s), platform support, performance, and maintainability.   But, I have not found any research that actually backs up the assumptions that users prefer the experience of a native app over a hybrid mobile web app (A hybrid app is a HTML5 app distributed in an embedded web view using PhoneGap, etc.).   Some  that native apps are more performant and have a better user experience, but why? Have there been any user surveys or analytics that indicate this user preference towards native? Does a photon exert a gravitational pull? I know a photon has zero rest mass, but it does have plenty of energy. Since energy and mass are equivalent does this mean that a photon (or more practically, a light beam) exerts a gravitational pull on other objects? If so, does it depend on the frequency of the photon? interpreting scatter plots I have plotted my predictors versus my response variable in order to be able to fit a good Poisson model to my data. However i am getting  those scatter plots for nearly all predictors which make me rather worried since including these predictors is making my residual deviance a value of 575 on 571 df(high enough) Thanks Why doesn't 'find' show this file?
