with a taste of wind?

This is the first paragraph of O’Henry’s short story ‘After twenty years.’
What does ‘a taste of rain’ mean? Does it mean ‘it was about to rain’?

The policeman on the beat moved up the avenue impressively. The
impressiveness was habitual and not for show, for spectators were few.
The time was barely 10 o’clock at night, but chilly gusts of wind with
a taste of rain in them had well nigh de-peopled the streets.

Force Finder to use only a single window?

I constantly find myself closing down Finder windows. It seems that every “reveal in finder” command pops open a new finder window. This creates unwanted window clutter since I almost never need more than one finder window open at the same time. Is there any way to force Finder to reuse the same window, or to open separate tabs instead of separate windows?

Umask doesn’t change after reboot

I’m new to umask so please correct me if i’m wrong.

We have a mac OS X file server at work with multiple SMB shares. Whenever users create files, they get created as -rw-r–r– as this is the default umask (022). I want to change it to (002) so created files will have -rw-rw—- as default. This way all users in the same group can access the files.

Apple advises to change umask like this:

sudo launchctl config user umask nnn

After doing sudo launchctl config user umask 002 I got the following message:

Configuration applied. You must reboot for changes to take effect.

I rebooted and got the following:

$ umask

what am I doing wrong, please advise.

I’m running OS X Server 10.10.3 Yosemite with Server.app 4.1

At what time will the payment be taken when buying bitcoin on an exchange?

So for example if you place a order for BTC when it is in a small dip (for example some minutes),
Will the usd dollar price you pay be equal to the price at the time you placed the order or when it it is actually confirmed? (when the dip is probably gone and you effectively bought bitcoin at a higher price)

What I really would like to know whether it is possible to effectively trade BTC (or other coins) on a minute to minute timescale.

Thanks for your answer,

MongoDB: Database too big to resync?

we have a mongodb cluster which takes about 3.7TB on the filesystem. One of our secondary nodes died, so we replaced it and started the resync.

The resync was started on 12 Jul 2017 and took until yesterday (6 Aug 2017) I can see the index rebuilding and immediately after that, I got the magical message (there are dbs before the test one):

[rsSync] initial sync cloning db: test
[rsSync] build index on: test.t1 properties: { v: 1, key: { _id: 1 }, name: "_id_", ns: "test.t1" }
[rsSync] building index using bulk method
[rsSync] build index done. scanned 0 total records. 0 secs
[rsSync] initial sync data copy, starting syncup
[rsSync] oplog sync 1 of 3
[ReplicationExecutor] syncing from: fr-mongo-c3-p3:27017
[rsBackgroundSync] we are too stale to use fr-mongo-c3-p3:27017 as a sync source
[ReplicationExecutor] syncing from: de-mongo-c3-b1:27017
[ReplicationExecutor] syncing from: de-mongo-c3-p1:27017
[ReplicationExecutor] syncing from: de-mongo-c3-p2:27017
[ReplicationExecutor] could not find member to sync from
[rsBackgroundSync] too stale to catch up -- entering maintenance mode
[rsBackgroundSync] our last optime : (term: 10, timestamp: Jul 12 05:29:26:14)
[rsBackgroundSync] oldest available is (term: 10, timestamp: Aug 3 06:24:29:9f0)

Now what can I do with this? First thing that comes to mind is to increase the oplog size and repeat the process. Second thing that comes to mind is to take the backup data, copy them to this new node and if this process takes less then 4 days, I might be able to make it.

Any other ideas? Or is my assumption completely wrong? Thanks for answers!

(Mongo version is 3.2.10, OS is Ubuntu Trusty)

How to distinguish between an insoluble ionic compound and an insoluble metallic compound?

Insoluble ionic compounds and insoluble metallic compounds could both have high melting points, insolubility, and no conductivity in water. Is there a way to distinguish between the two in a laboratory setting?
