    1. the learned think they know, or have it in their power to know every thing that it is possible for the human mind to be acquainted with.

      I think we feel this way now with the internet. But its really just a certain kind of knowing and a certain kind of knowledge. It also depends on how you choose to approach that knowledge.

    1. Net sales = gross sales – (customer discounts, returns, and allowances) Gross profit = net sales – cost of goods sold Operating profit = gross profit – total operating expenses Net profit = operating profit – taxes – interest Net profit = net sales – cost of goods sold – operating expense – taxes – interest
    2. Another equation to calculate net income: Net sales = gross sales – (customer discounts + returns + allowances) Gross profit = net sales – cost of goods sold Gross profit percentage = [(net sales – cost of goods sold)/net sales] × 100%. Operating profit = gross profit – total operating expenses Net income = operating profit – taxes – interest
    3. Another equation to calculate net income: Net sales (revenue) - Cost of goods sold = Gross profit - SG&A expenses (combined costs of operating the company) - Research and development (R&D) = Earnings before interest, taxes, depreciation and amortization (EBITDA) - Depreciation and amortization = Earnings before interest and taxes (EBIT) - Interest expense (cost of borrowing money) = Earnings before taxes (EBT) - Tax expense = Net income (EAT)
    4. Here is how you reach net profit on a P&L (Profit & Loss) account: Sales revenue = price (of product) × quantity sold Gross profit = sales revenue − cost of sales and other direct costs Operating profit = gross profit − overheads and other indirect costs EBIT (earnings before interest and taxes) = operating profit + non-operating income Pretax profit (EBT, earnings before taxes) = operating profit − one off items and redundancy payments, staff restructuring − interest payable Net profit = Pre-tax profit − tax Retained earnings = Profit after tax − dividends

      $$Sales Revenue = (Price Of Product) - (Quantity Sold)$$

      $$Gross Profit = (Sales Revenue) - (Cost)$$

      $$Operating Profit = (Gross Profit) - (Overhead)$$

      Earnings Before Interest and Taxes (EBIT) $$EBIT = (Operating Profit) + (Non-Operating Income)$$ Earnings Before Taxes (EBT) $$EBT = (Operating Profit) - (One Off Items, Redundancy Payments, Staff Restructuring) - (Interest Payable$$

      $$Net Profit = (EBT) - (Tax)$$

      $$ Retained Earnings = (Net Profit) - (Dividends)$$

    5. Net profit is a measure of the fundamental profitability of the venture. "It is the revenues of the activity less the costs of the activity. The main complication is . . . when needs to be allocated" across ventures. "Almost by definition, overheads are costs that cannot be directly tied to any specific" project, product, or division

      Revenue - Cost

    6. Net profit: To calculate net profit for a venture (such as a company, division, or project), subtract all costs, including a fair share of total corporate overheads, from the gross revenues or turnover. Net profit = sales revenue − total costs

    1. These findings reflect a broader discussion about the digital divide’s impact on America’s youth. Numerous policymakers and advocates have expressed concern that students with less access to certain technologies may fall behind their more digitally connected peers. There is some evidence that teens who have access to a home computer are more likely to graduate from high school when compared with those who don’t.

    1. Another way to look at it: The .NET Framework has essentially two forks. One fork is provided by Microsoft and is Windows only. The other fork is Mono which you can use on Linux and Mac. With .NET Core we’re able to develop an entire .NET stack as a full open source project. Thus, having to maintain separate forks will no longer be necessary: together with the Mono community we’ll make .NET Core great for Windows, Linux and Mac OSX. This also enables the Mono community to innovate on top of the leaner .NET Core stack as well as taking it to environments that Microsoft isn’t interested in.

    1. Thirty-two rural ISPs point to “the bureaucratic straightjacket of outdated regulations known as Title II” as a barrier to the vigorous investment they want to pursue.

      Is it uncertainty or a straight-jacket that these ISPs are burdened by? What aspect of Title II opposes deployment and development of their innovative ideas?

    2. Innovative providers hoping to offer their customers new, even free services had to fear a Washington bureaucracy that might disapprove and take enforcement action against them

      This statement compels me to see the issue from Pai's perspective. Should we trust that the government is acting in consumer's best interest more so than ISPs?

    1. the majority of Americans—57 percent—support the current net neutrality regulations that ban ISPs from blocking or discriminating against lawful content on the internet

      (Cited here.)

    1. bipartisan

      Both Consumer Reports and the University of Maryland concluded that a majority of Americans (in the latter case, a vast majority: 82.9%) oppose the repeal of net neutrality. (Local politicians, ironically, remain split along partisan lines.)

    1. 14 Dec 2017. The FCC just voted 3-2 to repeal net neutrality. Here, the ACLU explains what comes next. The Congressional Review Act could allow Congress to undo this action.

    1. The Federal Communications Commission voted on Thursday to dismantle landmark rules regulating the businesses that connect consumers to the internet, granting broadband companies power to potentially reshape Americans’ online experiences.

      The day the internet died...

    1. EFF explains aspects of the Internet that Ajit Pai pretends not to understand.

      Ajit Pai pretends not to understand that the only job of an ISP is to provide a connection to the network and transmit packets. He also pretends DNS is an information service provided by ISPs.

      Ajit Pai is a liar.

    1. telecom companies, which surged 2.7% to lead all sectors — a reversal of their futility so far in 2017, having dropped 12% year-to-date.

      yeah I don't think this is the tax bill, seems like it would be more related to repealing net neutrality to me

    1. The War for Net Neutrality in the USA won a battle in 2014, but in 2017 we are seeing a second battle which is more likely to be lost. Internet Service Providers (ISPs) are probably soon going to dictate what traffic can or cannot arrive at people’s end devices. GOOG-FB-AMZN traffic would be the most common, due to their popularity among internet users. Because of this market demand, ISPs will likely provide cheap plans with access to GOOG-FB-AMZN, while offering more expensive plans with full internet access. It is already a reality in Portugal.

    1. Although anonymous comments are "six times more likely to be an attack," they represent less than half of all attacks on Wikipedia. "Similarly, less than half of attacks come from users with little prior participation," the researchers write in their paper. "Perhaps surprisingly, approximately 30% of attacks come from registered users with over a 100 contributions." In other words, a third of all personal attacks come from regular Wikipedia editors who contribute several edits per month. Personal attacks seem to be baked into Wikipedia culture.

      Personal attacks come from frequent editors.

    1. Brace yourself to defend net neutrality (along with everything else) during the Trump kakistocracy.

      T-Mobile wasn't the only ISP to try to undermine net neutrality via zero rating. AT&T and Verizon have also been major offenders, particularly when it comes to zero rating their own content. By doing so, ISPs are using their position as Internet gatekeepers to funnel customers to their own content, thereby distorting the open playing field the Internet typically provides. While the FCC has begun to take measures to rein in some of the most egregious practices, it's clear that zero rating will continue to be a major battlefield in the fight for net neutrality.

    1. If we upgraded to competitive wholesale publicly-overseen fiber optic networks all over the country, we could leave the cable industry and its ongoing destructive shenanigans behind. (Without expensive upgrades, the cable guys can’t provide the upload capacity that fiber can.) Yes, it would be initially expensive to do this. But so was the railroad system. So were the highways.
    2. There are so many ways for the local cable monopolies to turn dials in their direction the way things are set up now. They can start charging more for peak-hour usage, so they never have to upgrade their physical facilities. They can start charging more for interconnection of Lane 2 with other networks. They can zero-rate a bazillion other services they provide and bundle them with their own “public internet” offerings. They can charge separately for their proprietary WiFi services nationwide — the new bottled water, the thing we ought to have access to in abundance for free.They can do all of this because most U.S. households have only a single choice of operator for download speeds greater than 25 Mbps. It’s even worse for speeds over 50 Mbps 
    3. Networks are built to meet peak demands. Comcast has already made this investment. No “power user” is having any effect on anyone else’s download experience within Comcast’s Lane 2 — there’s plenty of capacity. (The Netflix/Comcast fracas last year made this eminently clear: as soon as Netflix paid up, presto, Netflix subscribers weren’t faced with a spinning wheel.)
    4. Earlier this month, Comcast announced that it would be launching a $15 per month streaming pay TV service — cleverly named Stream TV — that wouldn’t count against the 300GB data plans (that number is the cap) it had already introduced in several states.
    5. It begins by announcing a data cap that’s set high enough to affect only a small percentage of current users who routinely hit it. Justify it by saying you’re only targeting the “hogs” who gobble up everybody else’s bandwidth. Say you’ll charge for data usage that exceeds that cap. Then sit back and wait. Eventually, increased usage by more Americans will bring millions into the fold. And presto: without lifting a finger, dominant players can charge more people more per month — on every side of every transaction, content sources as well as consumers — without expanding their facilities, much less upgrading to the communications capacity we need.
