Boost Statechart vs. Meta State Machine
...dware will be able to process a few hundred events per second.
Regarding CPU load, if the number of events to process is much lower than these numbers, Boost.Statechart overhead compared to MSM will almost certainly not be noticeable. If the number is much higher, you're definitely better off with...

Elastic search, multiple indexes vs one index and types for different data sets?
...at such large numbers of shards make the job of the coordinating node very CPU and memory intensive. It is usually a better idea to organize data in such a way that there are fewer larger shards. In case you would like to bypass this limit, which is discouraged, you can update the action.search.shar...
Most efficient way of making an if-elif-elif-else statement when the else is done the most?
...e(1000000):
the_thing = options[something]
...and note the amount of CPU time they use...
1.py: 160ms
2.py: 170ms
3.py: 110ms
4.py: 100ms
...using the user time from time(1).
Option #4 does have the additional memory overhead of adding a new item for every distinct key miss, so if you're e...
【BLE技术内幕】BLE技术揭秘 - 创客硬件开发 - 清泛IT论坛，有思想、有深度
...用send_LL(0x53,2402M)（注：2402M为信道频率）。这里还有一个问题，设备B怎么知道这个数据包是发给自己的还是其他人的，为此BLE引入access address概念，用来指明接收者身份，其中，0x8E89BED6这个access address比较特殊，它表示要发给周...
How to refresh app upon shaking the device?
...er should be deactivated onPause and activated onResume to save resources (CPU, Battery).
The code assumes we are on planet Earth ;-) and initializes the acceleration to earth gravity. Otherwise you would get a strong "shake" when the application starts and "hits" the ground from free-fall. However,...
When to use Tornado, when to use Twisted / Cyclone / GEvent / other [closed]
... the word "concurrency" to mean "concurrent parallel execution on multiple CPUs". Twisted can do concurrent I/O scheduling via asynchronous (callback-based) I/O. GEvent can do concurrent I/O scheduling via a micro-thread scheduler. In Twisted, using spawnProcess, this I/O scheduling can be transla...
How to read keyboard-input?
... Sleep for a short time to prevent this thread from sucking up all of your CPU resources on your PC.
time.sleep(0.01)
print("End.")
# If you run this Python file directly (ex: via `python3 this_filename.py`), do the following:

Is there any way to put malicious code into a regular expression?
... states at the same time, and backtracking can eat your lunch — and your CPU.
Denial‐of‐Service Solutions
Probably the most reasonable way to address these patterns that are on the losing end of a race with the heat‐death of the universe is to wrap them with a timer that effectively places...
Best practices for exception management in Java or C# [closed]
... of code to get by without it would "resolve" it), or whether it means the CPU is on fire and the system should do a "safety shutdown" at first opportunity. It sounds like Mr. Hejlsberg is suggesting that code should assume the former; perhaps that's the best possible strategy given the existing ex...
