ECMAScript Regular Expressions Lookbehind Assertions
From ECMAScript regular expressions are getting better!:
Lookarounds are zero-width assertions that match a string without consuming anything. ECMAScript currently supports lookahead assertions that do this in forward direction. Positive lookahead ensures a pattern is followed by another pattern:
const pattern = /\d+(?= dollars)/u; const result = pattern.exec('42 dollars'); // → result[0] === '42'Negative lookahead ensures a pattern is not followed by another pattern:
const pattern = /\d+(?! dollars)/u; const result = pattern.exec('42 pesos'); // → result[0] === '42'A proposal adds support for lookbehind assertions. Positive lookbehind ensures a pattern is preceded by another pattern:
const pattern = /(?<=\$)\d+/u; const result = pattern.exec('$42'); // → result[0] === '42'Negative lookbehind ensures a pattern is not preceded by another pattern:
const pattern = /(?<!\$)\d+/u; const result = pattern.exec('€42'); // → result[0] === '42' -

Calculating Delaware Franchise Tax
The Franchise Tax for a Delaware limited liability company (LLC) or Delaware limited partnership (LP) is a flat annual rate of $300 as of July 1, 2014.
The Franchise Tax for a corporation is a little more complicated. It is based on your corporation type and the number of authorized shares your company has. The total cost of the Franchise Tax is comprised of an annual report fee and the actual tax due.
A non-stock/non-profit company is considered exempt with the state of Delaware. This type of company does not pay the annual tax but must file and pay the annual report fee. The annual report fee is $25 per year.
A corporation having 5,000 authorized shares or less is considered a minimum stock corporation. The annual report fee is $50 and the tax is $175 as of July 1, 2014, for a total of $225 per year.
A corporation having 5,001 authorized shares or more is considered a maximum stock corporation. The annual report fee is $50 and the tax would be somewhere between $200 and $180,000 per year.
There are two methods to calculate a maximum stock company’s Franchise Tax. They are:
Authorized Shares Method
The state of Delaware uses this method to initially calculate your taxes. This method is calculated based on the number of authorized shares. The calculation is as follows:
- 5,000 shares or less: $175 (as of July 1, 2014)
- 5,001 – 10,000 shares: $250 (as of July 1, 2014)
- Additional 10,000 shares or portion thereof: add $75
- The maximum annual tax is $180,000
For Example
- A corporation with 10,005 shares authorized pays $325.00($250.00 plus $75.00).
- A corporation with 100,000 shares authorized pays $925.00($250.00 plus $675.00[$75.00 x 9]).
Don’t forget to add the $50 annual report fee to the Franchise Tax after it is calculated.
Assumed Par Value Capital Method
To use this method, you must give figures for all issued shares (including treasury shares) and total gross assets in the spaces provided in your Annual Franchise Tax Report. Total Gross Assets shall be those “total assets” reported on the U.S. Form 1120, Schedule L (Federal Return) relative to the company’s fiscal year ending the calendar year of the report. The tax rate under this method is $350.00 per million or portion of a million. If the assumed par value capital is less than $1,000,000, the tax is calculated by dividing the assumed par value capital by $1,000,000 then multiplying that result by $350.00.
The example cited below is for a corporation having 1,000,000 shares of stock with a par value of $1.00 and 250,000 shares of stock with a par value of $5.00 , gross assets of $1,000,000.00 and issued shares totaling 485,000.
- Divide your total gross assets by your total issued shares carrying to 6 decimal places. The result is your “assumed par”.
Example: $1,000,000 assets, 485,000 issued shares = $2.061856 assumed par. - Multiply the assumed par by the number of authorized shares having a par value of less than the assumed par.
Example: $2.061856 assumed par s 1,000,000 shares = $2,061,856. - Multiply the number of authorized shares with a par value greater than the assumed par by their respective par value.
Example: 250,000 shares s $5.00 par value = $1,250,000 - Add the results of #2 and #3 above. The result is your assumed par value capital.
Example: $2,061,856 plus $1,250,000 = $3,311 956 assumed par value capital. - Figure your tax by dividing the assumed par value capital, rounded up to the next million if it is over $1,000,000, by 1,000,000 and then multiply by $350.00.
Example: 4 x $350.00 = $1,400.00 - The minimum tax for the Assumed Par Value Capital Method of calculation is $350.00.
NOTE: If an amendment changing your stock or par value was filed with the Division of Corporations during the year, issued shares and total gross assets within 30 days of the amendment must be given for each portion of the year during which each distinct authorized amount of capital stock or par value was in effect. The tax is then prorated for each portion of the year dividing the number of days the stock/par value was in effect by 365 days (366 leap year), then multiplying this result by the tax calculated for that portion of the year. The total tax for the year is the sum of all the prorated taxes for each portion of the year.

macOS Sierra Universal Clipboard Issue with VNC (Screen Sharing) Shared Clipboard
If you like me owning more than one Mac and using one of them to control the other via macOS built-in Screen Sharing feature, you may occur this issue after you upgrade your macOS to Sierra.
macOS Sierra introduces a new feature Universal Clipboard which can share the same clipboard among iOS and macOS devices. This sounds cool, but as it’s technically a part of Continuity feature, it would require Bluetooth to work.
So the problem is, when I control my Mac mini from my MacBook Pro via Screen Sharing in the same network, with the Shared Clipboard enabled, the Universal Clipboard would still always try to “sync” copied content via Bluetooth instead of using Screen Sharing Shared Clipboard.
It’s ok if both of your Macs are at your hand, but it’s a disaster if they’re in different rooms, Universal Clipboard via Bluetooth would become really slow to connect to each other, and this issue could even make your VNC drop connection if you copy images to your clipboard.
So here’s the solution, just disable Bluetooth on your Mac mini, and wait Apple to fix this bug.

Pinboard 的誠意
Billing screw-up
Hello there,
Thanks for your recent $95 renewal of archiving! I am very grateful for your trust in Pinboard.
However, I made a coding mistake on the new Stripe billing page, and instead of being billed for the correct amount ($95), your card was billed for $0.95.
I’ve refunded this payment, and I’m afraid you’ll have to visit https://pinboard.in/renew at your convenience, and make the charge one more time. I have added three months to your archiving as an apology for my sloppy coding.
Kind wishes,
Maciej

Uninstalling letsencrypt – Let’s Encrypt Community Support
If you have the environment variable
XDG_DATA_HOMEset, the installation is located at$XDG_DATA_HOME/letsencrypt. Otherwise, it is located at~/.local/share/letsencrypt. You can simply delete this directory. You can also delete configuration, work, and log directories which by default are stored at/etc/letsencrypt,/var/lib/letsencrypt, and/var/log/letsencryptrespectively. The directory where you cloned our git repo can also be deleted.Let’s Encrypt also installs some OS dependencies and how you remove these would be very OS specific. To see what dependencies were installed, take a look at the files in the bootstrap folder at the root of our git repo (link). Take a look at the shell script for your OS to see what packages are required. You can uninstall these packages through the normal means of your OS, but make sure they aren’t required by any other programs on your system.

Update HP Laserjet Printer Firmware on OS X
If your printer firmware has official OS X version (for example LaserJet Pro MFP M476dn), just download the official DMG update and run it.
If your printer doesn’t have official firmware update for OS X, then you should:
- Download the Windows version firmware (any version should be ok)
- Extract the .exe using 7-Zip, you will get `product-update.acl`, this is the firmware update file
- Open HP Utility (the official HP Printer Software shipped with your pinter)
- On the menu, click “Show Advanced Options”, then you will see a “Update Firmware” icon
- Click it and choose the `product-update.acl` we just extracted from the package, then click “Update”
Then your printer status will be “Printing”, during update your printer will get disconnected for 1-2 minute(s), then it will be back to normal and shown as “Ready” on your printer LED display.
If you don’t like HP softwares and you don’t have it on your OS X, you can also update it with the following steps:
- Download Windows version firmware, extract it, the same as the “HP Utility” method
- Open Terminal, type
lpr ~/Downloads/product-update.acl(change the path to your real location)
Please note you have to set the printer you want to update as default printer, or you have to specify the printer with
