The mystery of how birds migrate long distances over land and sea is a step closer to being cracked.
By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just as you might reach for a magnetic compass to find which way is north or south, birds are thought to have an in-built "living compass". A chemical in the eye that is sensitive to magnetism could be proof of this theory, according to a new study. Peter Hore, professor of chemistry at the University of Oxford, said it could be that birds can "see" the Earth's magnetic field, although we don't know that for sure.
Open source repositories can be vectors for badness, so look before you run.
Counterfeit packages downloaded roughly 5,000 times from the official Python repository contained secret code that installed cryptomining software on infected machines, a security researcher has found. The malicious packages, which were available on the PyPI repository, in many cases used names that mimicked those of legitimate and often widely used packages already available there, Ax Sharma, a researcher at security firm Sonatype reported. So-called typosquatting attacks succeed when targets accidentally mistype a name such as typing “mplatlib” or “maratlib” instead of the legitimate and popular package matplotlib.
This exact thing happens to me, I've tried using APC, Tripp-lite, and CyberPower. The laser printer (not directly attached to UPS) but on same circuit warms up the fuser thus causing a brown-out condition on the circuit, then causing the UPS to activate to hold up the PC and other devices.. thus cycling its sealed lead acid 6v battery within a few seconds, causing them to go below 50%. This may work a few times but if it drops below 50% charge it damages the 6v battery.. thus will need to be replaced continually unless you move the laser printer or have the circuit conditioned to handle the greater load.
What I don't understand is why it sends multiple copies.
Because you are going over the maximum allowed attachment size. It's simply not supported.
What you should be asking is why gmail sends it at all. Obviously a bug i their system.
That being said - 25 MB attachment is not a lot. Some places mentions that the limit is actually 25MB total size with attachments being base64 encoded, which means that you will hit the limit somewhere around a 18 MB attachment.
If you send a lot of email attachments maybe it's time to look for another email provider.
