A gentleman phoned in to ask how the trees that you see growing along city streets and often encased by the pavement and concrete surrounds nevertheless are able to access sufficient water and nutrients.
We had quite an interesting discussion about it, but I thought I'd enquire what everyone here thinks too?
In the past I have publicly "outed" spammers and posted their email addresses and online personas / user ids so that a) others might be less likely to fall victim; and b) so that their email addresses will get harvested and they'll be targeted with a liberal helping of spam by their own kind.
I guess if i do this now then I am breaching data protection rules?
I'm now thoroughly sick and tired of emails asking for my consent to keep arriving.
I really wish the people behind them would just read the rules of the GDPR and take a much less pusillanimous approach. This is getting stupid.
The majority of the emails arriving are on lists that already have opt-out links attached anyway, so I could easily unsubscribe if I wanted to. And poor little organisations like the school alumni society are getting all stressed because they want me to opt back in too...
Honestly, the volume of spam that the misinterpretation of this legislation is causing is seismic!
At least by ignoring the bulk of them I'll be getting myself of the majority of marketing mailing lists for a while...
There seems to be a standard size for a loaf of bread, or at least a fairly narrow range of sizes (unless you a French, in which case you take long and thin to the extreme); but who decided how big a loaf ought to be in the first place? Is this a scientifically-informed decision, or purely based on practical considerations?
Sitting in my garden over the weekend I spotted a pair of blue tits setting up home in a nest box on the fence. This prompted us to start wondering whether they find a mate, then make babies, then build a nest while the eggs develop, then lay the eggs, or some other order.
I am trying to move into 21st Century display technology after about 30 years of using VGA connectors!
However, I'm a bit under-educated about HDMI and display port specifications. From my reading, HDMI is largely a consumer specification that carries audio tracks too; display port is an independent spec that doesn't do audio?
But are the connectors between the two interchangeable? Can I plug an HDMI cable into a display port "out" on a computer?
When a solution becomes saturated and no further solute can dissolve, why does raising the temperature enable further solute to be dissolved? In terms of the energetics of the system, why does the temperature change affect the carrying capacity of the solvent?
I've recently taken delivery of a new Surface Laptop, from Microsoft. It's actually very impressive and, at about 14h (at the moment), the battery life is the best I have ever had from a mobile device.
But what can I do to keep my battery - and my battery capacity - at its best for the longest time possible?
The accompanying instructions don't say much but they do counsel you not to leave the machine plugged in for extended periods "so that the battery can operate at normal temperature".
But this inevitably means that you are running off battery not the mains most of the time and therefore adding charge/discharge cycles to the battery, which is what causes electrode fragmentation and performance loss.
So what should I do? Run the thing off the mains when possible, or always run the thing off batteries?
And if the latter, should I run the battery all the way down before recharging it, or recharge when it gets to half way, a third...?
And what about storing the machine if it's to be left unused for a period? Store with the cells fully charged, part-discharged, flat?
This seems to be something of a minefield with a lot of misinformation circulating.
I don't know if anyone can answer this, because it's a bit technical and possibly beyond the scope of this forum, but I'll try anyway, and if anyone can help me that would be terrific.
I have been assigned a block of 5 public IPs by our ISP. The idea is to put certain NS resources - like codecs, recorders and ftp servers - onto these different addresses. Then they may be accessed publicly; port forwarding is not appropriate in this situation.
The VDSL modem / router supplied by the ISP has a "routed subnet" option that exposes the additional IP addresses to the Internet. However, as far as I can tell, these IPs are not behind the firewall that protects the LAN originating from the router (which is the DHCP server for the LAN 192.168.xx.xx subnet). The router also seems to lack a 1:1 NAT config option.
My questions are:
1) What is the best way to protect my downstream devices on those public IPs? Ideally I'd like to put some sort of firewall between them and the wider web.
2) Is there another way to build the config whereby I can put all of the devices on the same LAN, with a LAN address each, but then also route a public IP to them individually also?
