Securely storing environment variables in GAE with app.yaml
... ndb library which uses memcache and the datastore under the hood, so it's fast.
Update:
jelder asked for how to find the Datastore values in the App Engine console and set them. Here is how:

Choosing Java vs Python on Google App Engine
...t running last)
Currently, Python and using the low-level API in Java are faster than JDO on Java, for this simple test. At least if the underlying engine changes, that app should reflect performance changes.

Data structure for loaded dice?
...ndom Sampling Methods for Changing Discrete Distributions", 2019), and
the Fast Loaded Dice Roller (2020).
Other algorithms include the alias method (already mentioned in your article), the Knuth–Yao algorithm, the MVN data structure, and more. See my section "A Note on Weighted Choice Algorithm...
What is a “symbol” in Julia?
...t symbols are interned – i.e. hashed by the language implementation for fast equality comparisons – is also an irrelevant implementation detail. You could have an implementation that doesn't intern symbols and the language would be exactly the same.
So what is a symbol, really? The answer lies...
Why JavaScript rather than a standard browser virtual machine?
...at description, and these are new languages that are also still developing fast.
JavaScript is an ugly language, but through careful use of a selective subset of features, and support from suitable object libraries, it can generally be made fairly tolerable. It seems incremental, practical addition...
Pandas: create two new columns in a dataframe with values calculated from a pre-existing column
...
df["A1"], df["A2"] = calculate(df['a'])
This second method is also much faster on larger DataFrames
df = pd.DataFrame({'a': [1,2,3] * 100000, 'b': [2,3,4] * 100000})
DataFrame created with 300,000 rows

How can I obtain the element-wise logical NOT of a pandas Series?
...ame. This might have something to do with why np.invert(s) is no longer as fast as ~s or -s.
Caveat: timeit results may vary depending on many factors including hardware, compiler, OS, Python, NumPy and Pandas versions.

XSD - how to allow elements in any order any number of times?
...nts without the XSD 1.1 changes to all-groups becomes very unpleasant very fast (and for large n may may exhaust memory). It does not mean that they become impossible in principle.

I need to pop up and trash away a “middle” commit in my master branch. How can I do it?
...ou try to push after a rebase in this case, git will give you a reject non fast-forward merges error.
Revert is the correct solution when the branch has been shared with other repos. git revert af5c7bf16 will make a new commit that simply reverses the changes that af5c7bf16 introduced. This way the...
