Does it have to be a grid? I'd be inclined to group by house, and list the relevant packs underneath.

ya that's probably doable
Thanks
If it's not broken, fix it until it is.

But a pack would never be split by several houses, right?
I believe Richard is quite right.
That way you also get a delivery list per house.

I need to build an application whereby a PC that's already on the LAN needs to communicate with a PC that's newly connected to the LAN.
This is in Windows.
Is there a method in TCP/IP that a PC can use to broadcast, or advertise its machine name and IP address, so that another PC can listen for it and then connect via SSH?
Assume that I cannot use nslookup because in my experiments, it's not reliable.
Thank you.
The difficult we do right away...
...the impossible takes slightly longer.

I've used "arp -a" to list what a given PC "sees" (static / dynamic IP, MAC address).
The dynamic IP's can then be queried via nslookup for a machine name.
"Broadcasting" implies "listening" (on something) otherwise.

Thank you very much Gerry.
I'll see if I'm able to make use of that command.

You're welcome!
My ARP "sees" smart TV's etc. without me specifically "looking" for them; so there is some background work (in Windows) going on implicitly. (Same with a router's admin panel.)
(Asynchronously pinging a range of IP addresses on a LAN using a short timeout is another / additional way of looking for new addresses.)

You can google for "IP Broadcast".
Might want to make sure your needs are appropriate to that though.
For example some times (maybe always now) networks can suppress those.
And it isn't all that efficient nor necessarily even that reliable because it is hard to figure out if it failed because you are using it wrong or because it just didn't get there.
Since it is easier to throw up servers these days that is what people do.

Thank you.
I'll look that up.

Late response here, but look up SignalR. I've used it for just that - PC to PC messages. Really simply code.

Hello Everyone,
We are students from Germany and we are currently studying „Media-Design“.
We were assigned to create an artistic media-installation for the “Ars Electronica” as an entry in their competition. Our Idea is to visualize the process of an A.I. in an experimental way. This means, that we don’t know yet, what the final result is going to be.
However for that, we need some sort of input for our “generative art” project.
I myself am pretty familiar with programming algorithms and data-structures. I had some experience with JavaScript and Processing.
What we need is a simple all-purpose A.I., ideally one with neuro-evolution
(I found NEAT to be looking quite promising).
I want to emphasize, that we don’t require anyone to build or program a new A.I. If someone already built one, even a simple or small one, it would be sufficient. From what I understood from our research, the simplest and most basic form of A.I. is the one “recognizing hand-written digits”. But please no CNN. A simple multilayer-perceptron feedforward or NEAT is enough. We thought that a text-file, ideally some sort of exchange format (like XML or JSON) would be a great start, to understand the data we get out of the process.
Tl;dr:
- For a Project we need a neuronal network
- We want to visualize the learning process
- We need an API to get weights and neurons from an A.I. System that is learning.
- We just need a finished built A.I. (please no C.N.N.) ; No additional Programming needed
If anyone has interest helping us with our problem, feel free to send me a P.M.
Thanks in advance,
Best regards,
The “Sound of Synapse” Group!

I am currently doing an EPQ on architecture which is basically a project worth half an a level that goes along side the rest of my subjects where you conduct independent research into an area that interests you. The question I have chosen is "Does a high focus on environmental sustainability restrict the progression of architecture?" because I hope to study architecture at university.
This is the main title for my projects however I would also appreciate any comments/ opinions anyone has on:
Is sustainability of a buildings or its aesthetics more important?
what are your opinions on carbon neutral buildings and do you think its a reliable long term solution to buildings being bad for the environment?
do you have any examples of eco-friendly buildings that look unattractive or attractive?
Does a high focus on how eco friendly a building is push architecture into the future by making architects think in different ways ?
Can beautiful architecture and sustainability always have to "compete" or can they work together?
Any opinions you have on any of these subjects would be very useful in my research into my EPQ project. I will full reference anyone's comment that is used in my project and appreciate any thoughts you have weather you have a career in architecture or sustainability or not. THANKYOU!

Wrong kind of architecture - this is a software development site and has nothing to do with buildings or sustainability.
Th "architecture" this forum is concerned with refers to the high level structures of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. No bricks, no steel beams, no concrete, no straw bales, no recycled wood.

Just noting that there are many restrictions on architecture.
In terms of your specific comment one notes that right now one can only build to the best science that is known right now and that which meets codes. So even if you knew of a study that proved that a certain type of wood was bad and yet the codes required it you would be required to use it.
And what really restricts architecture is money.
wrote: ...or its aesthetics more important?
Look at the engineering problems with Frank Lloyd Wright's Fallingwater house as an example of aesthetics that went wrong.

I have a column in an SQL table, whose values might be updated by multiple clients at the same time.
All clients access DAL through Asp.net WebAPIs + Win Form application.
How do we ensure , only one client updates the value at a time consistently?
If it's a client side code, I would just use locks/Mutex . How do we do this in server?
I guess "static" methods are a poor option.
Should I go for any Queuing mechanism?
Please suggest what's the right method to handle this simple concurrency requirement.

I'm an old systems programmer. Now forced to do some fancy DB projects. So trying to figure out, how things work.

You hit a multitude of topics; related and unrelated.
Without more focus, you made it near impossible to give you a "straight" answer.

lol I see it now, when I read my question again. 
My own experience is all about putting Critical sections & mutex to use to handle similar scenario's without involving DB.
I was all thinking to control just with plain client code. Just like ensuring the entry gate is atomically protected or ensuring the calls reaches sequentially there through a proper queue.
But Linq/SQL providing features out of the box, is awesome.

You could always use rowversion[^] in the table.
So you're going to edit a record. You first do a SELECT on the recordId you want, getting the data for the record and it's rowversion value. When you go to UPDATE the record, you include the recordId and the rowversion values in the WHERE clause for the update.
If the rowversion matches, the update will proceed and you'll get back a 1 for 1 record updated. If the rowversion doesn't match, you'll get back 0 for no records updated. That means the record has been updated between the time you did the SELECT and the UPDATE.

Thanks you very much. Will try this out.
But does the transaction in Linq automatically takes care of this issue? dbc.SubmitChanges() will do this automatically?
|
|
|
|

Not necessarily. Transactions have nothing to do with concurrency.
EF has a Timestamp attribute you can stick on a byte[8] field in your database class for this.

What you're talking about is not handled by Transactions. Transactions make sure a group of operations on the database are handled as a single unit. They makes no claims to concurrency.
