java - JSR 107 - Caching (JCache) vs CPU caching -

-

I have read about JSR 107 caching (jachet).

I am confused: everybody who knows, every CPU manages its caching memory (with no help from the OS).

So, why do we need a Java caching handler?

Thanks

There is a difference between CPU caching and memory caching. This will cache things in the zacate memory, so you do not have to get it from expensive resources on disk or network.

Therefore, the cache is created in the CPU so that they can avoid going to memory. The CPU typically has three level caches and 8 MB around the store. CPU caching does not have to worry about anything because it has been taken care of for you. If some CPU is not in the cache, then it has to be taken out of memory.

It is like avoiding caching in the memory in memory or avoiding slow resources. As I mentioned earlier, the mechanisms have control over the programs so if you want to constantly ask your DB for some object, then you It can store memory and return to the same object. This has left a little bit of performance. As Thomas mentions Jacques, JVM adds functionality to be able to provide caching. What I understand from this means that different Java programs can share the same cache.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
