Submission + - Ask Slashdot: What's the best way to take out a drone? (cnn.com) 1

shanen writes: Trying to make lemonade here, though I fear we may be on the verge of a fresh conflagration in the Middle East... I don't think international assassination is a viable or sustainable substitute for diplomacy. It might feel nice, but one country's terrorist is too often another country's national hero. The trick of turning one into the other almost never works... And even Trump wants to walk around his golf courses without worrying about every passing drone. (I also predict Kim Jong-Un is going to be rather less visible going forwards.)

So... The best outcome I can imagine is if the response is limited to ending drone warfare. That would be bad in some ways, mostly because increasingly unrestricted drone warfare has been largely advantageous for America (so far), but I think it's the least bad outcome I can imagine here. Maybe you can see a better glide path for the future?

Which leads to the topical question: What's the best way to take out a drone? And who is most likely to exploit those market opportunities? If China is just in it for the money, then I think they could make a bundle by selling some anti-drone system, though I think they'd have to disguise it or multi-purpose it in some ways. You know, just to confuse the international response (as if Trump was capable of building an international coalition to oppose anti-drone warfare).

So you're saying that the government over-spends $20K 100 million times every year? That's dumb.

On top of that, who says this was not an OK use of money?

"This is another sad day for the taxpayers in the United States," Rep. John Mica, the Republican chairman of the Transportation and Infrastructure committee, said. "This sounds almost unbelievable to have this kind of waste reported when we're running trillions in dollars in deficit makes absolutely everyone's blood boil."
The outrage was bipartisan."

It was $20k for 4k people. That is $5/person. OMG! The government spent $5 per employee at a party? Holy shit! Panic now! My wife works in the private sector and they blow way more than that per employee at her company parties.

Nothing like taking numbers out of context to make your point.

Talking about taking numbers out of context; you're ignoring the total cost: $268,732 on a one-day conference
Another conference: "GSA Inspector General revealed that the agency had spent $822,751 of taxpayer funds to conduct the Western Regions Conference in Las Vegas, Nevada."

I know reading is hard, but perhaps you should read the article I linked too.

If the GSA spent $20K wastefully, spread among three hundred million people that's less than one percent of one cent that you contributed. That $20K did not affect you in any noticeable way.

So you're saying that the incident I linked to was the only time the the government wasted taxpayer money? Come on, David, look at the big picture.

This time, the agency is being investigated for spending $268,732 on a one-day conference for its Federal Acquisition Service division on Nov, 17, 2010, in Arlington, Virginia.
More than $20,000 of taxpayer money was spent on drumsticks for 4000 attendees, more than $8,500 for an appearance by someone called 'Agent X', according to the preliminary findings of the Inspector General. The event, which was held at the Crystal City Gateway Marriott just outside Washington, D.C., also included expenses of more than $35,000 for picture frames, $20,000 in catering charges as well as additional funding for a violinist and guitarist.

Last April (2012), the GSA Inspector General revealed that the agency had spent $822,751 of taxpayer funds to conduct the Western Regions Conference in Las Vegas, Nevada.

The government should provide us tax software or a website where we can file our taxes. The side effect of Intuit, H&R Block, et. al. providing the free filing is that they get our financial details. Now days with data breaches...

One year I paid $18,000 in taxes and then the news came out about the GSA spent $20K on drumsticks. Made me sick. Yes, my family should do without a 2nd car, braces, health insurance, or whatever so that the GSA can throw a party!

Comment Re:Question: Why does DoH provide any more privacy (Score 1) 97

The amount of extra effort to do reverse dns lookups on customers compared to hosting their own DNS server and logging things there. The latter is cheap and easy, the former isn't.

Reverse lookup is not needed for HTTPS which uses SNI.

SNI addresses this issue by having the client send the name of the virtual domain as part of the TLS negotiation. ...
The desired hostname is not encrypted, so an eavesdropper can see which site is being requested.

Anyone along the path can have a peek at where you're going. DoH doesn't ensure your privacy. This is just a ploy to wrestle control of DNS resolution from the network administrator.

frankly this might be the only way to get them to "upgrade"

There are some people, perhaps many, that don't want the advanced "features" of Windows 10 (telemetry, forced reboots during an inconvenient time, hard drive data loss, broken DHCP client, tablet GUI, etc).

Many years ago I never shied away from running Windows updates. I knew they were going to fix things and make them more better. Not anymore. I need a functioning workstation that doesn't pilfer through my data.

Incarceration is an ineffective deterrent to a person that doesn't understand or care what tomorrow brings.

This is not true. Incarceration can and should lead to a person beating their drug habit. I know there are illegal drugs in prison but that's a separate problem that needs addressing.

The real scary thing is that every economic class is susceptible to addiction.

This is so true. There are various forms of addiction, not limited to drugs, where people destroy their lives. Gambling is one. Others?

Use the right tools for the right jobs

I agree. Notice the word 'tools' is plural. Colitti is only offering one tool. With that viewpoint, when I need to cut a two-by-four, you'd be only offering a hammer and not offering a saw.
They make both toothpicks and two-by-fours. Let me decide with which one to pick my teeth and which one to build my house.
You know they make both Apache and Nginx. I understand both are good. Let me decide which one best serves my needs. Having a choice is good.

you'll find that you have no need for DHCPv6

So, how many devices are on each of my 10+ networks? How many ISPs do I have? How many VPNs? Is there any radiology equipment on my network? Time clocks? Cameras? Alarms? Wireless access points?
You know nothing of my networks or their needs; yet you presume to tell me what is best?

it's a principled stand that DHCP is the wrong way to allocate IPv6 addresses

Oh, really? So how do you pass out the other 78 pieces of information that a device might need?

There are very good reasons for IPv6 devices to have multiple addresses, and for them to be able to generate addresses the network operator doesn't know about, for privacy.

Note, I didn't say there weren't good reasons. There is a way to request multiple IP addresses built right into the DHCP request protocol. There's also IPv6 prefix delegation where you can request a block of IP addresses.
If you don't trust me with your privacy, you shouldn't be on my network.

that's what 802.11x authentication is for

There you go making assumptions about my network. 802.11x doesn't work for wired connections.

Not to mention that 252/253, aka 99.6047% of the network traffic being sent down your connection would not be destined to you, leaving you with 0.00406% of the bandwidth your line is capable of.

Nowadays people use switches instead of hubs. A switch only sends non-broadcast traffic to the device that answers the ARP request. I have two different ISPs that each use a /25 CIDR and it works well.

There would be many more devices using IPv6 if Android would support DHCPv6. But thanks to Lorenzo Colitti's refusal to implement a DHCPv6 client, most Android devices don't support DHCPv6. His argument that if DHCPv6 were implemented, devices would only get one address is nonsensical. I want to know the device name so I can trouble-shoot if there's a problem. If you're on one of my networks, do DHCP or you don't get any address. Plus, I don't want you to tether devices behind your phone on the network I'm responsible for.</rant>

Another problem along this line: As far as I know, only Windows sends hostname in a DHCP request. I need to know the hostname so I can update DNS. This is a good starting point when trouble-shooting a misbehaving device.

With IPv4 and NAT, I can decide on the server whether to forward traffic to ISP#A or ISP#B. Now with, IPv6 the device decides which public address to use, ISP#A or ISP#B. Linux has enough tools to NAT the ISP#A public address to a ISP#B address for out-going traffic, but now we have NAT again.

After I move (or transfer) money from my savings account to my checking account, it won't be in both places; although I wish it would.

Facebook et. al. may allow you a copy of your data but they're not going to remove their copy once the data has been sent.

I have the same beef with the status line of browsers. "Transferring data from http://www.blah.com/". So blah.com doesn't have it anymore? No, the browser is receiving data from blah.com.

Years ago I looked forward to Windows Update keeping my system current and squishing bugs. With Microsoft's new direction, not anymore.

1) upgrade trickery: My wife had a laptop that I didn't want to update to Windows 10 and just clicked the X (close) box. I didn't realize it would just update anyway. How many people were fooled this way?

2) Windows 10 telemetry: No, I don't want Microsoft to slurp my data. Sure you aggregate the data and store is securely on your server. But then I continuously read about companies' data breeches. I never want my Passwords.txt posted on the internet. I can't imagine how this data slurping could be HIPPA compliant. I have a lawyer as a client that has to open the SSH port on the router when I need to get in and do some maintenance on their server. They want to protect their clients' data. Lol, a few months back they updated all their PCs to Windows 10.

3) retroactive telemetry: Microsoft retroactively installs telemetry along with security updates on previous versions of Windows. This wasn't what I originally signed up for!

I'm actively trying to reduce the amount of Microsoft software I use.
