I needed a simple cache solution using with flask and therefore used SimpleCache of werkzeug. I used to cache some json data returning from inner modules such as list of things, list of that, list of this; using a pattern similar to this one:
With a managable and smart expiry timeout (ie. 20 secs), this worked nice.
There were 3 problems in front of me,  on each action, I needed check if result is on cache, if not evaluate the action then push to cache, then code comes messy; so it should have had simpler usage  I needed to extend the timeout so that application is less busier overall, and  whenever a user makes a data manipulation, I needed to remove the keys with some specific pattern for the user.
Looking around, I found nearly nothing in terms of w/pattern key deleting.
At least, I found the LUA script sheerun shared on stackoverflow. Then wrote a method wrapper which would check the cache for me and if nothing there, evaluate the result and push it into the cache. So this section would be “more” automized.
Pushing to the cache…
This is the wrapper:
defgetFromCacheOrSet(callable, *params, **opts):
key = opts.get('key', callable.__name__) + '.' + '.'.join(map(unicode, params)).encode('utf-8')
to = opts.get('timeout', 30)
extendTime = opts.get('extendTime', False)
v = __cached.get(key)
if v is None:
v = callable(*params)
__cached.setex(key, to, v)
if extendTime: __cached.expire(key, to)
return v #fromCache
except Exception as e:
print('Error: get from cache fai
What it makes is that, if you would like to run a multiplication method such as multiply(4,16) you pass the method, its parameters to the wrapper so that it takes care of getting from the cache or evaluating. The point is wierdest line is obviously the “key” section which makes itself a key for the cache. Key is builded from the name of the method and its argument values.
For multiply(4, 16) key becomes “multiply.4.16″, if you rather would like to choose another string for this operation, you can pass it as key=”MultiplicationOp” in opts as in:
key value is mandatory only if you used it while setting the value (obviously). Warning should be this, in here there is no 2nd argument which get to be 16 here. This is because we would like to delete all “multiply.4.*” keys.
The LUA script which I call before the methods above:
__cached = redis.StrictRedis(host='localhost', port=6379, db=0) ##### db1 !
__DEL_LUA = ("""local keys = redis.call('keys', ARGV)
for i=1,#keys,5000 do
redis.call('del', unpack(keys, i, math.min(i+4999, #keys)))
__cached_del_keys = __cached.register_script(__DEL_LUA)
I have had the problem authentication with my ssh server with a private key. It asks password despite no password needed. Here is the log:

So it appears that, I tried to use PuTTY gen generated key file with OpenSSH. Therefore, without windows I had to use the steps:
1) This installs putty along with puttygen: (MacPorts needed)
$ sudo port install putty
2) This converts my ssh keygen into OpenSSH key type:
There are nice samples for pair programming solutions. Well, I have seen a few, too.
I needed a simpler and quicker solution so here I went like this:
add to end of /etc/bash.bashrc:
if [[ -z $TMUX ]]; then
if [[ "x" == "x$TMUX" ]]; then
# if not a new tab of tmux
if [[ 0 < $(ps -ef | grep -e "#######" -e tmux | grep -v "#####" | wc -l) ]]; then
exec tmux a
exec tmux -2
I have obtained a brand new Lumia 920. Actually it is a long story why I have chosen a Windows-based device of a company which I have hated as a software vendor. The point is, as per my long experiences, Microsoft is a great keyboard and mouse producer and which should stay that way.
I haven’t got any xbox experience. However, according to word of mouth, I have somehow grown the prejudice of a great device.
What I have seen, since 1992 starting with MS-DOS, have left a stinky smell of software experience. However just the contrary for hardware.
Within such a dilemma, addition of my brother’s incredible marketing of his windows phone and his experience, I just have given a shot.
My iPad still exists, but I wanted to see if I could have replaced it with this Lumia toy, with the confidence I have acquired by reading cover-to-cover two foreign language booksnd much much more articles on my E-72. (No, it was this century)
What I am looking for as a function in a device –whatever it is-, is to have the ability to read “things” even offline. That’s why I have bought an iPad 2 two years ago despite its really high cost. I have started to explore the applications of windows phone store for this purpose. Here what I have got lately:
First I tried to search for the first application I (used to) use the most: Instapaper.
1) Stacks For Instapaper
Integrates with Instapaper.
Long story short: No, not this one. Just because it is trial, only 1 article to download from instapaper doesn’t make it real trial (2 in fact, but one of them is the manual). I don’t know how it behaves when large articles come. I know sounds like everything. However, no try no money. Not this one.
I don’t know how the search matched this application but, this is rather an RSS reader with offline support. However I admired the “mobilizer” choice. This way you can choose to view the article simplified with one of Readability, Instapaper, getPocket, Google rendering engines as you wish. (bootstrap removers) Although could not understand what happens when, good feature anyway. I tried to choose readability engine but seems like, it just doesn’t download the readability version. It just puts a button to convert into Readability rendered versions “if” you have connection at that time. Anyway, ok.
However not happy with offline loading… It is (so to say) offline reading capable application but you have to get into the article to load the article really to have it offline. So, no offline mode is not OK.
Especially images… So much trouble. It doesn’t even state if the article is fully downloaded or not. You just have to check. If you have downloaded, then yes, you have the article with you. (It says “Caching images” when the app starts; but wait it doesn’t move anywhere, it takes forever)
Themes; ough! It doesn’t state however, if you want to change into another look, after changing, you must exit the application and start again to apply. Despite really great colors and 7 different themes, it should show me what I choose instantly.
Supports 5 fonts for now. Which contains my favorite Georgia. Fine.
Still have problems with resuming application. (you know the idea; go back to the application and go on from where you’ve left)
Not my type. But I guess because of the unique themes I just keep it.
It lacks of feedback. Just simple as that. You have to give feedback to the user, what you are doing right now. Really. I can’t understand if the application is trying to download or render or … whatever. Statusbars are filled and emptied and filled again and lots. And sometimes vibrates which means, well, I don’t know. (vibrate each time going to the main list?? really?)
Resuming just fails. Too much waiting. (I don’t know what happens next, just haven’t waited that much)
6 of fonts, and no Georgia or Garamond. Instead there is Times. Really?
Text to speech is a good idea. Reads the text to me. Really good one. However, I would rather choose “OK” button to close the font menu instead of builtin phone “back” touch button.
As to the benchmarks, Lumia 920 has a good CPU among the class. However nearly 2 seconds to open the template color dropbox made me this angry. The developer obviously wanted to put colors to the items, but functionality really lacks.
“View images”… If there is no image, you should test the “view image”. It’s fun to look at an empty space.
