Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

aaarrrgggh Re:IPTables and OpenVPN (238 comments)

Ironically, it is the licensing of openvpn (not that open) that makes the problem.

Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

aaarrrgggh Re:eBay a Cisco ASA 5505 (238 comments)

I love our work ASA5505, but it is a bear to configure properly unless you know what you are doing. High point with me is the ease of connecting on the client end.

Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

aaarrrgggh Re:IPTables and OpenVPN (238 comments)

Do you use OpenVPN from iPhone/iPads in your environment? Can't stand the client I have from OpenVPN.com.

Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

aaarrrgggh Re:Why VPN? (238 comments)

One big reason is to avoid all the "cloudy" ways to allow remote access to things like cameras, storage, security. Another incentive might be to route all (say) netflix traffic to a VPN so that it doesn't get throttled by your ISP.

Ask Slashdot: Advice On Building a Firewall With VPN Capabilities?

aaarrrgggh Re:geek or not (238 comments)

I've had miserable experience with Buffalotech reliability, and would recommend Asus and the RT-AC-66U in a heartbeat. The custom firmware adds a lot of nice functionality including OpenVPN with GUI.

For non-paranoid, non-geeks, avoid OpenVPN in my book.

Home Depot Confirms Breach of Its Payment Systems

aaarrrgggh Re:CC system is flawed (111 comments)

It is easy if the security token is a single-purpose device; hard if it is a smart phone.

Home Depot Confirms Breach of Its Payment Systems

aaarrrgggh Re:Junk quality; why bother? (111 comments)

Most local family-owned shops are effectively Ace or one of the other franchises. While not all the inventory comes from the franchiser, it's quality is usually lower to be at the same retail price. Lowes seems to have higher quality, higher-priced products consistently, but it seems to miss the balance on the value scale.

I bought a Husky tool cabinet last year for under $300, where the comparable product from Lowes was $700. Lowes was hands-down better in terms of construction quality, design, and features... but for my needs the cost wasn't warranted.

Know when you want/need quality, and know when you need to get the job done. The product is the key though, not the merchant.

aaarrrgggh Re:CC system is flawed (111 comments)

It is easier than that; the token needs to have merchant, amount, date/time hashed in; you approve that information before entering your pin.

There are hard issues... like what to do with credit reports that rely on a non-random 9-digit social security number as keys to the kingdom, but securing the transaction between consumer, merchant, and bank isn't that hard.

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

aaarrrgggh Re:Anthropometrics (818 comments)

Where? I fly domestic first class, the same issue prevails. It is bad design, period. Either lock out recline or do the slider seat reclines. Only other option is to remove tray tables.

3 Recent Flights Make Unscheduled Landings, After Disputes Over Knee Room

aaarrrgggh Re:Anthropometrics (818 comments)

The solution is simple, make the recline shift the reclining passenger's seat forward so the recline stays within their volume of space.

Or, eliminate the recline altogether.

Power Grids: The Huge Battery Market You Never Knew Existed

aaarrrgggh Re:Yes, we know that. (245 comments)

You are mixing units to your detriment-- think in kW not kWh. You are also incorrect regarding efficiency; when you pay for your demand up front efficiency is much more incentivized.

Airbnb To Hand Over Data On 124 Hosts To New York Attorney General

aaarrrgggh Re:It is a public safety issue (149 comments)

See, the rules work! ;)

On a serious note though, fire regulations are only one of many differences; accessibility, ventilation, energy all are different between long term and short term housing.

Munich Council Say Talk of LiMux Demise Is Greatly Exaggerated

aaarrrgggh Re:LibreOffice (190 comments)

The GP is referring to the classic problem of collaborating with a single document. Party A provides base information, B edits information, A reviews changes and makes further updates. Collaborating with a PDF is called markup, and relies on a single party to be responsible for editing. Not sure if Google Docs does a good enough job on resumes yet to work.

Airbnb To Hand Over Data On 124 Hosts To New York Attorney General

aaarrrgggh Re:It is a public safety issue (149 comments)

Because transient residents are not intimately familiar with the fire escapes and layout of the building. Smoke compartments must be smaller, low-level exit signs are generally required (so someone can see them when crawling), and requirements for secondary exits are different. And... you must post a sign at the door indicating exit locations.

I am torn on the issue; in a place like San Francisco or NYC, the issue of taking units out of the rental pool is quite serious. This becomes worse where you have rent control. On the flip side, it is nice to have options when you stay in a place without sufficient traditional lodging offerings. Bed and breakfast establishments aren't really my cup of tea personally, but having a small apartment or house for a few days can put you more in the center of a community.

For Microsoft, $93B Abroad Means Avoiding $30B Tax Hit

aaarrrgggh Re:Okay... and? (316 comments)

It is hard to make that work in the US because taxes for a person and corporation are essentially treated the same (sans FICA/FUTA). This eliminates many of the easy tax shelters for individuals; a low corporate tax rate re-opens these issues.

For Microsoft, $93B Abroad Means Avoiding $30B Tax Hit

aaarrrgggh Re:Okay... and? (316 comments)

While it has been 15 years since I had to deal with this, using your numbers you would owe no US taxes. You exclude the first roughly $100,000 in income, so the US would see your income as $100k, and you paid $68k in taxes already, and would have only owed about $25k in the US.

The only gotcha is that you need to spend less than 35 days in the US per year.

The capital gains is a bit of a bitch if you have anything meaningful, but that is a the price of entry into the US market.

It's Easy To Hack Traffic Lights

aaarrrgggh Re:Welcome to the Information Age! (144 comments)

There is one option; the PLCs fail to a "safe" mode and ignore the network if the validation PLC (not networked) detects an anomaly. Stoplight timing is out the window, but green lights in all directions would not be possible.

It's Easy To Hack Traffic Lights

aaarrrgggh Re:Welcome to the Information Age! (144 comments)

I started to rebut your comment... but then actually came to agree. The cost of fixing this problem is huge; any traffic light pedestal could be an entry point from a "trusted" point on the system, and I have seen several in Los Angeles unlocked. Effectively the problem is reduced to if you have physical access to the machine there isn't much you can do for security.

Is Storage Necessary For Renewable Energy?

aaarrrgggh Re:Some can be done - and is. Most is bull. (442 comments)

The PV Watts gives ambient temperature and wind speed data in the hourly CSV output, and I just created a formula to calculate available wind energy for the given wind speed and turbine efficiency. The microhydro was just a basic reserve calculation on my elevation change, reservoir volumes, and average monthly rainfall; my intent was to try and use it as a dump load as well, but it wasn't effective.

The project included a greenhouse, desalinization system, and I was cooling a thermal mass during the afternoon when I had available power. The desalinization system could run for 3 hours and generate 24 hours of water consumption, not 3 hours at peak load.

How many days are you planning for a battery? I found I didn't have many discretionary loads that could be deferred for more than 3 days which drove storage substantially when I wanted to limit generator run time; I needed it 80+ days per year with a 3-day battery.

There are likely some math errors on demand side (especially looking at installed HP for some motors rather than going to the trouble to calculate BHP), but the general results seem rational.
