He Got Game (1998) reviewed by: Paul B. Miller
Director: Spike Lee
In the pre-release hype for "He Got Game," marketers made sure that, by repeating the film's release date (May 1) over and over like a mantra, it was engraved in our memory. And yet a more appropriate release date for the Spike Lee's new film would have been one month before, on April 1, or the day after the NCAA Basketball Tournament finals (Kentucky won again, in case you forgot). For without a doubt one of the strongest sides of this solid but ultimately disappointing film is its definitive commentary on the sleaze and hypocrisy of the recruitment process in big-time college athletics.
Lee's portrait of Jesus Shuttlesworth, the most sought-after high school basketball player ever, communicates a convincing moral truism that all of us ordinary, anonymous people know or should know already: that fame and stardom, those most envied and coveted of attributes, are in many ways unenviable burdens, because you can no longer be sure just who your friends are and just who is gravy-training. If you were Kobe Byrant, how complicated would it be to go out and make a new friend? Whom could you trust?
Jesus is in fact surrounded by Judahs, including his high school coach, girlfriend, and uncle-guardian, who try to cash in on his lucrative future. He is left to fend for himself in a sea of sharks, a feat requiring almost as much skill as on-court prowess. In one particular scene, an NBA agent tries to woo the him with a Rolex and a Ferrari whose stereo system "costs as much as a small trailer home.". The real drama of the movie, however, revolves around a certain irony: Jesus's father Jake (Denzel Washington) also wants to profit off his son's talents. If he can convince Jesus to attend Big State University, the governor will cut short the time he is serving in the state penitentiary (for having accidentally killed his wife, Jesus's mother). Is Jake a gravy-trainer like the rest? Or is it a father's prerogative, especially given his circumstances, to make such a request of his son?
That dilemma unfolds brilliantly in the film, and Ray Allen's performance and presence on the screen are a wonderful surprise. His voice and delivery qualify him as a bonafide talent. Director Spike Lee deserves tremendous credit for both casting and directing here (NBA stars Travis Best and Rick Fox also give credible performances). And yet the film suffers from a certain unevenness. The very least I expected was unforgettable basketball scenes, and, granted, the one-on-one match-ups between Father and Son (one flashback when the father is twice the size of the son, one climactic scene when the son is a head taller) are well done. But the pick-up game depicted towards the beginning of the film rather disappointing. I have yet to see a fictional "basketball movie" that successfully captured the real rhythm of a full court game -- the moves, jump shots, steals, blocks, dunks, and fast breaks. While Lee assembles these elements in a fast-moving sequence on a grandiose scale, with lavish cinematography and the music of Aaron Copeland's "Hoe-Down," the scene suffers the same misfortune as the cathedrals in Spain: that is, we are not permitted enough visual distance to take in the entirety of the spectacle. Our vantage point is on the court, from within the lane, and I somehow kept wishing I had a cheaper seat. While other reviewers have referred to Copeland's sound track as "unforgettable," I found the "Hoe-Down" sequence to be incongruous, the sounds coming from the court drowning out the music and relegating it to the background. The "Appalachian Spring" introduction, accompanying images of people playing basketball all over the country, is more effective.
Those, however, are merely the quibbles of a reviewer who also happens to be a basketball fanatic. There are other weaknesses in the film that are more serious. We all know that one of Spike Lee's biggest problems as a director are the women in his films, and "He Got Game" is no exception. One of the potentially most interesting aspects of the story is the relationship between Jake and his daughter Mary (Zelda Harris), Jesus' younger sister. Mary is a strong character, whose relationship with her father is different from Jesus' and whose independence adds to the complexity of the other characters. Yet she dissapears almost entirely from the second half of the film in favor of the manly one-on-one confrontation between Jesus and Jake. Likewise, Jesus' Aunt Sally (Michele Shay) is a positive character, one of the few who refuses to even discuss the idea of profiting off her nephew, yet she too dissappears, never to be seen again, though kowtowing Uncle Bubba (Bill Nunn) reappears in a new Lexus. The other women who frequent the film are, frankly, sluts and whores, from the coeds at Tech University who like to sleep with basketball players, to the bare-breasted sex-kittens whose services are hired to convince Jesus to matriculate there. Jesus's girlfriend Lala (Rosario Dawson) doesn't fare much better. Her self-serving financial motivation is portrayed in a quasi-sympathetic light (there's no way her relationship with Jesus will survive, why not make some money off it?), but she also sleeps around behind his back, lies, and, in another flashback, is shown to be the one entirely at fault for an unwanted pregnancy.
But the episode that almost ruins the film, in my opinion, involves the relationship between Jake and the (yet another!) prostitute (Milla Jovich) whom he saves from the clutches of some evil pimp. Not only does she set aside her professional motives to pleasure Jake free of charge, he, of course, practically reforms her at the end. Though the performances in this sub-plot are decent, how can viewers possibly take such a preposterous cliche seriously?
In the end, we are left with a good film, but one with serious faults. I agree with Roger Ebert that the final scene is "daring and original" but I am more wary of its effectiveness. No doubt "He Got Game" stands above "White Man Can't Jump," "Blue Chips," "Hoosiers," "Eddy," et. al, but "Hoop Dreams" retains the title as the definitive basketball movie.

1. The major dairy co-operative companies have been discussing industry
rationalisation for some years. In 1998 impetus was given by the then government's
policy of producer board reform. As early as 1996, savings of $250m had been
identified, and industry strategic plans were being drawn up. In 1998 a consultant's
report from McKinsey and Co. suggested that the direction the industry should take to
improve returns would be to expand offshore through mergers and acquisition, while
establishing onshore a Megaco-op. This would integrate the great majority, if not all, of
the processor co-operatives and the Dairy Board into a single united company
(Producer Board Project Team, briefing papers, p.6).
2. After dialogue with government and negotiations with industry leaders, the Dairy Industry Restructuring Act (DIRA) was developed and passed in September 1999. The Act addressed the key public policy issues relating to the proposed megacoop. If it had become effective, the DIRA would have:
3. The legislation only came into effect if the merger was approved by farmers, authorised by the Commerce Commission, and had become effective by September 1 2000. To establish the megacoop required the merger of co-operatives accounting for at least 75% of the shares in the Dairy Board (effectively a merger of at least two of the largest co-operatives, NZ Dairy Group and Kiwi Co-operative Dairies). A merger of the co-operatives required support of 75% of the votes cast, with votes held by supplier shareholders on a milk solids supplied basis (ibid, pp.6-7).
4. Thus, while the DIRA was enacted in 1999, its entry into force was dependent on
producer agreement to a megamerger of the main processing companies and
Commerce Commission authorisation of the merger (MAF briefing papers). Under the
Act, the Dairy Board's single desk powers were to be repealed from 1 September 2000,
and the new merged company (MergeCo
) would have the full right to export to
restricted markets for a period of six and a half years, phasing down over the following
four years. Following that, access was to be allocated by a new company (Quotaco
),
with the objective of maximising returns to its shareholders (who will be farmers,
initially at least).
5. The then government wanted to encourage reform of the producer board system and appeared to be offering powerful incentives to get the process started. While co- operative ownership of the Dairy Board had been established under the Dairy Board Amendment Act 1996, control over the quotas was needed to continue to exploit any existing trading advantage the Board held delegated responsibility for.
6. The industry's initial application to the Commerce Commission in mid 1999 received a negative draft determination and was subsequently withdrawn. The Commission considered that the anti-competitive costs outweighed the benefits. The Commission expressed particular concern that farmers would lack choice about whom they could supply milk to. They were also concerned that domestic consumers would have limited choice of suppliers of dairy products. The Commission noted that much of the asserted benefits were able to be gained without a megaco-op. The industry would have to address the Commission's concerns, including in particular the right for farmers to exit the megaco-op with the fair value of their capital, if the application was to be successful (Producer Board Project Team, p.9).
7. After the Commerce Commission draft determination, the two major companies entered into detailed discussions of a possible merger taking into account the Commission's views on domestic consumers2. Details of these discussions have not been made public though it is clear from remarks made by Graham Calvert, chairman of the mega-merger establishment board, that agreement could not be reached on the terms of the merger.
8. From various announcements, it appears that the establishment board had available
to it a report or series of reports setting out the benefits and costs of the merger under
various scenarios. In respect of these reports Mr Calvert said: There was such an
extraordinary difference in the balance sheets of the companies, and they had done
such different things. When you come to getting the 75 per cent farmer vote, you were
never going to get them to agree without a business plan
, and Kiwi has more
indebtedness and half the production. The Northland move [by Kiwi] would just
compound the problem
(The Dominion March 31, 2000).
9. So what were these mechanisms over which the companies could not agree? This paper sets out what I think are the corporate finance issues that crop up in the circumstances. These are derived from corporate finance books and not from the said reports which are not publicly available.
10. The basic aim of the firm is to increase company value. Company value
is the
extra wealth created by the activities of the firm. Normally the creation of wealth
appears on the equity side of the balance sheet. Profits before interest and tax (EBIT)
represents this concept. A more refined concept is Economic Value Added (EVA).
EVA is the profit/surplus after the full cost of capital has been accounted for. It is
defined as after-tax before-interest net operating profit
minus the cost of capital. The
cost
of capital is the weighted average cost of debt interest and the risk-adjusted
expected return on equity (WACC) as determined by the capital asset pricing model
(CAPM). Thus if a firm is creating economic value, its profit must exceed the true
opportunity cost of capital across the whole firm.
11. Market Value Added (MVA) measures how the market values the firm looking
forward. Other things being equal, MVA is the present value of the future stream of
value
as defined by EVA created by the firm.
12. Healy (2000) has noted that a high proportion of firms on the stock exchange in New Zealand have a negative EVA. Across the board, in recent years, this represents a tremendous loss of company value which some corporates do not appear to address. A similar exercise carried out on NZ sheep farms would show a similar result. Sheep farmers do not make enough profit to service their debt and earn a comparable return on their equity invested.
13. In the case of dairy companies, equity is held by the suppliers to the companies in a co-operative structure. The aim of maximising the increase in company value could therefore be expressed at one of several levels. First, the profit to the company after the opportunity cost of capital employed is accounted for (EVA); second, profit before interest and tax as in the EBIT model; and third, the operating surplus/profit available to suppliers for both their ownership of equity and their raw material supplied.
14. Now it is characteristic of co-operatives that their balance sheets do not distinguish
between the rewards to equity and the rewards for raw materials. In fact, as Hussey and
the Round Table (1992) have pointed out a number of times, the two returns are
bundled
together in the payout system used. This has serious implications for
resource use decisions when the individual prices are not known. Bundling also makes
it difficult to sort out the costs and benefits of a merger proposal.
15. In the absence of information from the co-operatives themselves we have to speculate what the basis of estimating shareholder value might be.
16. The situation is that two separate co-operative companies' balance sheets have to be merged together and equity issues in that merger addressed. Equity is taken to be represented by shareholder value before and after the merger. Shareholder value is defined as the addition to equity of the respective company, i.e. earnings before interest and tax. In this formulation, total capital cost has yet to be addressed and will be a mixture of debt and equity returns. If one company holds more debt than the other, then the proportion of profit available for return to shareholders is going to be less.
17. One company may pursue a high debt regime so as to enjoy the tax benefits on interest charges (and enjoy greater growth more quickly). Another company may prefer to work on a high equity-low borrowing base and forgo the tax benefits available as well as some potential growth. The tax benefits can be considered a government contribution to a company's investment programme - the so-called tax shield. These considerations then have a bearing on the weighted cost of capital for the EVA calculation.
18. The merger process itself involves a comparison of what each company would have achieved without the merger compared with what would be achieved with the merger. It is therefore necessary to construct the with-and-without situation in terms of company value. Consider Figure 1.
Let ON = NZ Dairy Group current profit before interest and tax;
OK = Kiwi current profit;
OB = combined current profit.
Let KP = growth of Kiwi profit as a stand-alone;
NQ = growth of NZDG as a stand-alone;
BR = combined growth path;
BS = growth of MergeCo.
Then the present value of the added value stream KP is the current estimate of company value in the Kiwi company before interest and tax;
the present value of NQ is the current estimate of company value in NZDC; and
the present value of BS is the current estimate of merged company value.
19. Then the with-and-without situation is:
for Kiwi pv of BS - pv of KP,
for NZDG pv of BS - pv of NQ
Now if the prospects for one company on its own are better than the other company, apart from size considerations, then the merger favours the lower prospects company. This is because in the merged company all shareholders would be treated equally in terms of payouts etc. This is inherent in the structure of co-operative companies. Payout will be in proportion to the raw materials supplied. If there is an inequality between the two companies then some sharing arrangement is needed for sharing the benefits of the merger. In the case of Tui and Kiwi, and Kiwi and Northland, this took the form of a cash payment from the lower prospects company to the higher prospects company (The alternative would be to go down the path of a share swap in the registered company case, i.e. one Kiwi share is swapped for 1.2 Tui shares; but dairy companies do not have market valued shares!)4 .
20. Now since we do not have all the details of the projected growth paths of the existing co-operatives, their relative earnings, and the growth path and earnings of the merger, it would be futile to try and assess the details that go to make up the company earnings profiles. There is a certain amount of information around though, such as:
* debt servicing per kg ms is higher in Kiwi
* local market prospects tend to favour Kiwi
* size of operation and cost efficiencies favour NZDG
* terms of Tui merger with Kiwi
* terms of Northland merger with Kiwi
* terms of NZDG merger with South Island Dairy Co-operative.
21. The differences in size and trading returns in the two companies for the 1998-99 season can be seen in Table 1. In terms of milk solids (ms) delivered, Kiwi is about 5/8ths the size of NZDG. There is a big discrepancy in earnings (EBIT) which is due to different policies with regard to payments to suppliers. Operating profit before payment to suppliers looks to be a more comparable measure of performance. Production and revenue was much higher in the 1999-00 season.

22. It appears that in the co-operative system, EBIT is what you make of it. Table 2 shows the relationship of EBIT in both companies in 1998-99 to what I have called gross return to shareholders. It appears that company payouts to farmers for milk solids have been financed in entirely different ways hence giving quite different estimates of profit trends.
| Table 2: Structure of Gross Return to Shareholders | |||
|---|---|---|---|
| Financial item | Kiwi | NZDG | |
| Profit/Loss before tax | $ m | (9.835) | 146.369 |
| Interest | $ m | 43.473 | 29.656 |
| EBIT | $ m | 33.638 | 176.025 |
| EVA* | $ m | (102.0) | 34.2 |
| Payment to suppliers | $ m | 896.402 | 1434.780 |
| Payment to suppliers | cents/kg | 362 | 363 |
| Gross return to shareholders | $ m | 930.040 | 1610.805 |
| Gross return to shareholders | cents/kg | 372 | 417 |
| * EVA = cost of total capital @ borrowing rate. |
As might be expected, EVA is negative for Kiwi in that year, but NZDG was well in the clear. For the record, the EVA entity was worth minus 41 cents per kg ms in Kiwi and +9 cents per kg ms for NZDG.
23. It has been stated that the benefits of the merger are $300m per year in present value terms. It is not clear how many years it will take to get to that level. This is said to be an EBIT measure. So let us assume that NZDC can earn an additional $50 m per year and Kiwi an additional $75 m per year and both growing. (Assumption is that after the merger, all suppliers are treated equally). If we assume that the growth rate is 10% per cent per year and the discount rate is also 10% per year, then the increase in company value for NZDG is approx $500m (in present value terms) and that of Kiwi $750m. Spread over the 1998-99 combined output of 636m kg ms the differential is about 40 cents/kg ms.
24. That is, Kiwi suppliers stand to gain more from the merger than those of NZDG. Therefore NZDG directors would argue that Kiwi shareholders should pay for the privilege of joining the merger (Remember that is what Kiwi did to Tui). Thus NZDG is said to have made an offer to Kiwi that it would agree to the merger if Kiwi paid NZDG 40cents per kg of milksolids supplied! This Kiwi refused to do.
25. It may be that $250m is the net advantage to Kiwi in the merger. They gain more from the merger. Since it is a benefit generated by the merger, should Kiwi share the net benefit with NZDG? That is, they give NZDG only 20 cents of the advantage and keep 20 cents! Since 40 cents is the figure given to me by the managers it may be that the net advantage to Kiwi was 80 cents and a half way split would produce the compromise 40 cents!
26. The terms of the Tui-Kiwi merger appear to be that Tui suppliers would have 50 cents per kg ms taken out of their payouts over 3 years to make up this kind of compensation payment. For 1998-99 ex-Tui suppliers were paid $3.52 kg ms and suppliers other than ex Tui suppliers $3.62 (Annual Report p.34). On the face of it, the compensation was not paid directly to Kiwi shareholders but passed through the books of the merged company as a payout differential. The more recent agreement between Kiwi and the Northland Cooperative Company involves a 40 cents transfer, which presumably will be treated in the same way.
27. The terms of the merger of NZDG and the South Island Dairy Co-operative, effective 31 May 1999, included a divestment to NZDG shareholders of a 50% interest in NZ Dairy Foods. The interest was in the form of Class B shares. These shares carry an entitlement to half the dividends declared by NZ Dairy Foods. At the same time, eligible NZDG shareholders received a one-off $80m payment in July 1999 which equates to approximately 19.5 cents per kg of ms (Annual Report 1998-99, pp.28, 50). The latter appears to be a form of compensation to the existing shareholders before a merging of the books which has yet to go through the merged NZDG books.
28. As a side issue, the way these payments are made affects their tax status. In the Tui case, the payment passes through the payout system and appears as farm revenue (or farm revenue foregone). In effect, the transfer becomes a tax deductible expense for both sides. A capital payment to Kiwi shareholders would be tax free. In this case the transfer would have cost Tui shareholders even more! Presumably these concerns apply to any merger situation.
29. I am not entirely clear how the differential between the companies arises. In 1998- 99 the cost differential of interest on borrowings was worth 10 cents/kg/ms (Kiwi had been funding capital development by borrowing while NZDG had been ploughing back its profits). The margin in operating costs (pre payout) was 73 cents/kg/ms in favour of NZDG (but is there a different mix of products and processing costs involved?). Total revenue per kg ms favoured Kiwi by over 60 cents/kg/ms. These rough figures suggest a margin in favour of NZDG of around 13 cents/kg/ms based on the 1998-99 returns. What is important, of course, is the trends of these items in the future, taking into account mergers which have taken place since that date.
30. Since writing this last paragraph, Kiwi have announced their annual payout for 1999-00 (The Dominion, June 21). Kiwi posted a record payout of $3.82/kg/ms which included a record company premium of 47cents/kg/ms. Kiwi processed 382m kg ms and reached a record turnover of $2.6b. Presumably this was the influence of the Northland merger which took place during the year.
31. Discussion with executives of NZDG put down the failure of the merger discussions to a number of broader issues which went beyond the mere details of the balance sheet calculations. The merger documents required some assessment of future trends. But establishing the current position of the companies was compounded by problems associated with the effects of the recent changes in the industry on any assessment, e.g.
* absorbing the South Island Dairy Coop merger into NZDG' s books;
* absorbing the Northland merger into Kiwi's books;
* absorbing Food Solutions (Huttons) purchase by Kiwi;
* changes in the payment system introduced in 1999/00 (shift from cost
* engineering to 9 product categories said to be marginally priced).
The two companies also have different views on the reform of co-operative principles and have differently paced programmes of capital development.
32. The information available suggests that NZDG was pursuing a more corporate
model in the merged company. In particular the McKinsey report envisaged a future
where outside capital would be brought in and the equity shared with other interests.
In turn this would require a full unbundling of the payout system. The Kiwi company
appeared to want to retain the co-operative system with its emphasis on farmer control,
maximum payouts to suppliers, and continued bundling of payouts. It [the business
plan] didn't say where we got the money from for acquisitions overseas, or what we
were going to buy
(Calvert). These are large philosophic differences to overcome.
33. This paper is only about the analytics of the merger process and not about deregulation per se. Obviously other issues are important like the attitudes of Ministers, the views of the Commerce Commission, the uniqueness of the Dairy Board, and the presence of competitors in the wings. It will be interesting to see what emerges at the end of the day.

2) Consulting Economist, Wellington<EMAIL_ADDRESS>3) It is understood that the two companies had taken into consideration the need for shareholders to receive a fair entry and exit value for their shares. This would be critical to ensuring that there was at least the threat of competition in the market for raw milk supplies.
4) Bryan Smith points out that the key limiting factor on a share swap is the definition
of a qualifying company
under the Dairy Board Act. Under the Act a dairy
coopersative must issue shares to its suppliers in proportion to the milksolids they
supply to the cooperative in order to qualify for Dairy Board shares.

My special interest: Programming languages and techniques
``it is possible to make the structure of the program match the structure of the problem being solved.´´ — Burge
a bidirectional program than can be run
an element in/from a data structure.
A two-for-one bargain!
Forward
L.set(L.prop("x"), 2, {x: 1})
L.modify(L.prop("x"), x => x+1, {x: 1})
Backward
L.get(L.prop("x"), {x: 1})
Lenses are actually mapping functions:
map :: (a -> b) -> s -> t
Like list map:
map :: (a -> b) -> [a] -> [b]
Except lifted in some fashion, e.g.
map :: Functor f => (a -> f b) -> s -> f t
map :: Profunctor p => p a b -> p s t
Mapping functions:
mapList :: (a -> b) -> [a] -> [b]
mapLhs :: (a -> b) -> (a, c) -> (b, c)
compose:
mapListLhs :: (a -> b) -> [(a, c)] -> [(b, c)]
mapListLhs = mapList . mapLhs
mapLhsList :: (a -> b) -> ([a], c) -> ([b], c)
mapLhsList = mapLhs . mapList
And this is how we get the direction of lenses.
And others such as prisms, folds, getters, setters, ...
They can all share the same type (*)
And compose with each other
partial.lenses
which is my optics library and used in these slides:
But there are also many other optics libraries!
// Nest, Param, Organize, Removal, Traversal, Fold, Transform
const sampleTitles = {
titles: [{ language: "en", text: "Title" },
{ language: "sv", text: "Rubrik" }]}
L.get([], sampleTitles)
You have a data structure that...
...is more complex than just a single object or array.
And you need to update parts of that data structure.
Optics decouple the operation to perform on element(s) of a data structure from the details of selecting the element(s) and the details of maintaining data structure invariants.
In other words, a selection algorithm and data structure invariant maintenance can be expressed as a composition of optics and used with many different operations.
Compare to e.g. containers, iterators, and algorithms in the C++ STL.Atom
get
and set
LensedAtom
Kefir.Atom and Karet.Util libs
var state = U.atom({
titles: [{ language: "en", text: "Title" },
{ language: "sv", text: "Rubrik" }]})
var titleIn = language => ["titles",
L.find(R.whereEq({language})),
"text"]
var enTitle = U.view(titleIn("en"), state)
var svTitle = U.view(titleIn("sv"), state)
enTitle.log("en")
svTitle.log("sv")
state.modify(L.set(["titles", 0, "text"], "The title"))
There is a/are composition operator(s).
(+) :: T -> T -> T
There are simple universal laws that specify how they work.
x + (y + z) = (x + y) + z
zero :: T
x + zero = x
zero + x = x
Monoid is just an example!
L.compose(...os)
— Monoid (unityped)L.lazy(o => o)
— Fixed pointL.choices(...ls)
— SemigroupL.choice(...ls)
— MonoidL.chain(x => o, o)
— MonadPlusL.pick({...p:l})
— ProductL.branch({...p:t})
— CoproductL.seq(...ts)
— Monad
const elem = 2
const data = {x: 1}
const lens = "x"
const eq = (a, e) => R.equals(a, e) || a
R.identity({
GetSet: eq( L.set(lens, L.get(lens, data), data), data ),

Mike's Mets Player Review Series: Jacob Rhame
by Mike PhillipsNow that the 2019 season is over for the New York Mets, we have been looking back at the year that was. After taking a more general view of the offense, pitching, and coaching staff, it’s time to take a deeper dive into the Mets’ players. This series will take a look at every player on the roster for the Mets at the end of season from A (Pete Alonso) to Z (Daniel Zamora). The review will look at their season statistics, stories, and what role (if any) they will have next season. We continue the series today with a look at relief pitcher Jacob Rhame.
Player Review: Jacob Rhame
Jul 19, 2019; San Francisco, CA, USA; New York Mets pitcher Jacob Rhame (35) pitches against the San Francisco Giants during the ninth inning at Oracle Park. Mandatory Credit: Stan Szeto-USA TODAY Sports
2019 Stats:
Minor Leagues (2 Teams): 21 Appearances, 20.2 Innings Pitched, 3-2 Won-Loss Record, 5.23 ERA, 1.21 WHIP, 3 Saves, 25:6 K:BB Ratio
Major Leagues: 5 Appearances, 6.1 Innings Pitched, 0-1 Won-Loss Record, 4.26 ERA, 1.89 WHIP, 5:9 K:BB Ratio
Story: After failing to do much in the big league bullpen in 2018, Jacob Rhame was even less of a factor for the Mets in 2019. Rhame was a frequent flyer on the Syracuse shuttle, but he ended up making only five appearances at the big league level. Control was the big issue for Rhame with the Mets, as he walked nine batters in just 6.1 innings pitched, and explains why he never really gained the trust of manager Mickey Callaway.
Grade: D
Rhame’s ERA was decent, but the peripherals indicated that he wasn’t very effective at the major league level.
Contract Status: Pre-Arbitration Eligible
Odds of Returning: 50%
2020 Role: Middle Reliever
The Mets kept Rhame on their 40 man roster after the season, but he is out of options, so the Mets would have to DFA him in order to keep him in the organization next season. There is a decent possibility Rhame doesn’t even make it to spring training since the Mets may have a better use for his 40 man roster spot in free agency. Even if he does make camp, Rhame will have to win a job in camp in order to secure his Mets’ future.
Check back tomorrow as our Player Review Series continues with a look at shortstop Amed Rosario!

Tuning MethodologyThis section explains why it is important to follow a structured, goal-oriented methodology in your tuning efforts if you want to achieve optimal results. The methodology I use involves these five steps as shown in Figure 4.1.
The following sections describe each of these steps individually and explain why each step is important to the final outcome. Sometimes, there are situations for which you dont have an answer to the problem or perhaps you dont even know what the problem is. In the long run, however, a little analysis is worth more than a lot of trial and error. Examine the ProblemThe first phase in tuning the system should always be the determination phase. First, see whether you even have a problem. You may just be at the limits of the configuration. To make sure, examine the system, look for problems, and make this determination logically. The determination phase consists of examining the system as it currently is, looking for problems or bottlenecks, and identifying hot spots. Keep in mind that performance problems may not always be obvious. Here is a partial list of some areas you should examine:
I prefer to categorize performance issues into the following three classes:
For the first class of problem, you may have to take drastic action. Tuning may solve the second class of problem. For the third class of problem, you need take no action. Here are some questions to ask yourself when examining the system and searching for problems:
If you answer yes to any of these questions, you may be seeing some performance problems that can be fixed. In some cases, you have reached the limitations of your hardware and should add an additional CPU or perhaps some more disks. If you answer no to all these questions, your system may be running very well. However, you should still periodically monitor the performance of the system to avoid future problems. Determine the ProblemOnce you have decided that there is some sort of problem in the system, make a careful analysis to determine the cause of the problem. At first glance, it is not always obvious what the problem is. You may see excessive disk I/O on a certain table that may lead you to believe you have an I/O problem when, in fact, you have a cache-hit problem or an index problem that is causing excessive I/Os. Take a few minutes to think about the problem. Decide what area you believe the problem to be in. Thinking through the problem can help you avoid a long trial-and-error period in which you randomly try different things without positive results. At this stage, note-taking is a must. By writing down your ideas and thoughts, you can better organize them. If you have to go back and rethink the problem, your notes will be very useful.

Check you have the error I've encountered by looking up the nonlinear solver under
Tools > Extension Manager...
"Error: The status of this extension is unknown".
The plugin was written for OpenOffice, not LibreOffice. You have to fix this by uninstalling LibreOffice and then installing OpenOffice.

Approaching the last month of Ada Developers Academy, I was wracking my brain to think of a capstone project which would be both fun and educational. I mused to myself, 'when will I ever again have the opportunity to do any project of my choice with so much support?'
I went big and chose to program a drone. I mean, really, what more fun project could there be? What other project would have such rewarding and immediate feedback? Write some code, fly a drone! I thought it be great. And it was great, and not great, all at the same time.
Along with the usual struggles of a capstone, the time crunch, the hours and hours of research, I realized there was a problem which pervaded every step of the project from the very beginning. So much so, that I almost switched to a new project before I even began.
That problem is one which exists throughout the tech industry, and it is simply the lack of accesibilty to tech for people who are not already in tech. It is a catch 22. If you don't already know something, it is hard to learn anything about it.
I don't look to jump over 7-foot bars: I look around for 1-foot bars that I can step over. -Warren Buffett
Except there were no 1-foot bars...
While expressing all of this to my partner, my project hit a turning point when he looked at me and said, "Then why don't you bridge that gap?
 A video about Ada Developers Academy with some shots of the drone (at 1m30s)!
Overview
We will be using lots of tools to build an app, a server, and a front page with simple buttons to control the flight of your drone. We will also learn to stream the drone's video on it's own server and then to your front page.
This project will progress smoothest if you have a basic understanding of HTML, CSS, JavaScript and the ability to navigate the terminal. Even if you don't, you should be able to copy the code and understand the gist of what it is doing.
We will also be using several other tools and libraries, including, but not limited to Express, AR-Drone library, AR-Drone-Png-Stream library.
Don't worry too much about all the tools we will eventually need to use. We will discuss them in depth when we come to them.
We cannot take more than one step at a time. - Orison Swett Marden
I can't promise that the way I have set up everything in this drone is the best way ever, but that's the great thing about programming, there are a million ways to do everything.
Let's talk about the drone itself.
Hardware - About the Drone
After some amount of research into drones (I won't say a great deal of reasearch honestly), I chose the Parrot AR.Drone 2.0 for the hardware of this project.
I decided on this specific drone because it had all the required hardware, can be programmed with JavaScript (which I was pretty comfortable with) and was within my budget (on sale!).
The first thing I did when I got the drone home was put the battery on the charger while I set up my file. It takes about an hour and a half to fully charge the battery.
The drone assembly was quick and easy. There is a place on top of the drone for the battery to sit, held in by velcro straps and connected to the wires.
I chose to use the indoor body because I wanted to not destroy my drone blades, walls, or furniture. It slips on easily over the camera, then onto the drone.
While that battery charges, shall we set up our file?
Flight from a File
Overview
In this section, we are going to set up a javascript file install a library which will allow us to control the drone with a bit of code.
The completed project can be found on github
We will be using the following:
- JavaScript
- Atom (or any text editor of your choice)
- node
- node package manager (npm)
- node-ar-drone
First, go to the node package manager link and follow the instructions there to install it. The npm install includes node as well.
From here on out we will use npm to download the libraries we will need.
File Setup
In the terminal:
mkdir <your directory name> cd <your directory name> touch app.js npm install ar-drone
Open the app.js file and paste in these lines
var arDrone = require('ar-drone'); var client = arDrone.createClient();
Your files should look like this:
Now we have a client, which is our drone. This is the place in which we can write code to tell the client what actions to perform. I would recommend poking aroung the ar-drone library and see if you can figure out how things work and what actions are available.
The next step is to write code to control the drone's movement from within the app but first, there is something very important we need to do.
Cap Max Altitude (a tale of caution)
When I first set up my file, I got ahead of myself and wrote a quick take off, turn, and land block of code and ran it. I didn't realize the default max altitude on the drone was 23.5 meters! The drone flew, with significant force, directly up into my ceiling and bounced around like a moth trying to find a window.
We should set the drone's max altitude to a reasonable number, and avoid flying your drone directly into the ceiling.
Open the test-Client.js file, you will find it in node_modules>ar-drone>test>unit
Change the altitudeMeters to the height you want (line 87 in the image below).
On that note, the drone's emergency shut-off maneuver is to flip it to a 90 degree angle, essentially tip it so the top is pointing at the wall.
Be careful though, I had welts on my thumbs for days from accidentally grabbing too close to the propellers.
Write Commands
Next we are going to write a few lines of code to tell our client what we would like it to do, as shown in the node-ar-drone library.
client.takeoff();
client
.after(5000, function() {
this.clockwise(0.5);
})
.after(3000, function() {
this.stop();
this.land();
});
All together it should look like this:
Fly Drone
And thats it! We can go to our teminal and, while in our project folder, type in node app.js, hit enter and the drone flies the pattern we gave it!
This is another point at which I would suggest checking out the documentation for the node-ar-drone library. Find out what maneuvers the drone can do. Play around with them a bit.
We will get to video stream and app front end next.
Video Stream
Are we ready to move on to the video stream?
Library Install
We will use npm to install the ar-drone-png-stream library. In your terminal type in:
npm install ar-drone-png-stream
Update App
The next step is to require the library in our app.js file with the following:
require('ar-drone-png-stream')(client, { port: 8000 });
Here we are requiring the library, telling it which client we want to stream png images from and which port we would like to stream those images.
I do recommend commenting out the flight code, so we can temporarily stream video while drone is “on the ground.” It is optional, but I find it much easier to trouble shoot and work on a stationary drone.
If you chose to do so, your file should look like this:
We also need to install the http library because the ar-drone-png-stream requires it. In the terminal run npm install http
.
So, let’s stream video.
Those numbers are coming from the ar-drone-png-stream/index.js file. See line 22 in the image below.
While you are there, let’s check out the code and see what it is doing. You will see this line of code:
png.on('data', sendPng);
This line says, when there is new png data, call the sendPng function. Within the sendPng function is res.write(buffer);
, this line where the image is written to the page.
In much of society, research means to investigate something you do not know or understand. Neil Armstrong
Spend some time looking around in the ar-drone-png-stream folder, check out the readme, look around the index.js file, etc. It will always serve us well to understand the libraries we are using.
Building a Front End
Ready to have a front end and build buttons to control the drone?
Overview
In this section we are going to use Express, Socket.io, and http(which we met briefly in the previous section), to build an app front page with buttons to allow us to control our drone. We are also going to embed the png stream onto the page.
Library Install
First step is, as always, to install our libraries. In out termal, lets run these commands
npm install express
npm install socket.io
Express is a javascript framework. It is free, open source and minimal. Basically we will have the flexibilty to do what we want, and our project doesn't need much structure. We have no database, only one page, etc.
Socket.io is a JavaScript websocket library. We will discuss websockets in a bit when we start using it.
Create HTML Page
We also need make a new file called index.html, where we will put the html for our front page. In that file type in your basic html tags
In body of the html document, type in a message of your choice (I chose "we are in!"")
Update App
Let's go back to app.js and require the libraries we just installed. Note that we are also creating an app variable, which allows us to create an express app.
var express = require('express');
var app = express();
var server = require("http").createServer(app);
var io = require('socket.io').listen(server);
All together it should look like this.
Let's connect our app with our html. In app.js paste in this code:
app.get('/', function(req, res){
res.sendfile('index.html');
});
Notice the res.
again. We are telling the app to send the index.html file when it receives a request to get
the main app page '/'
.
The next step, I think, would be to get the index.html to show up in our browser right? Well, we already created a server for our express app with the line
var server = require("http").createServer(app);
Now we can paste in the following code to let it know we want it to listen to port 3000. We also have added a console log, so we can see in our terminal what is happening.
server.listen(3000, function(){
console.log('listening on *:3000’);
});
Check in browser on http://localhost:3000 you should see your message.
And also in our terminal we should have our console log.
Congrats! You now have an app with a client side (front page) and server side (app.js), but whats next?
I guess we probably want to put things on that front page, like buttons, which will send commands to the app. Then we probably want to add functions in the app which will tell the drone what to do. That is great and all, but you are probably wondering how our client side communicates with our server side and visa versa.
Ah! Excellent question. Let's go over that next.
I think one of the easiest ways to handle what we need is with web sockets.
Web sockets basically allow for information to be passed back and forth from client side to server side. It is basically an open line of communication between the two. I like the explanation on the PubNub "What Are WebSockets?" page, largely because it contains graphics and graphics are great.
Luckily, we already installed and required socket.io. We even told it to listen to the server. Now we can get right to work.
The first step is to tell it what to do when someone connects and disconnects from the server.
Paste the following code between our app.get block and the server.listen block.
io.on('connection', function(socket){
console.log('A user connected');
socket.on('disconnect', function() {
console.log('A user disconnected');
});
});
It should look like this:
When we run the app, whe should also get our console logs.
I am going to walk you through creating the take off and land buttons and function. After that, you will be able to add any other functions you would like your app to have.
In the body of the html in the index.html file paste the following code:
We just created two buttons. Lets look at the Take Off button.
We are telling it when the button is clicked onClick
, to call the takeOff()
function. Same with the take off button and it's corresponding function.
We also created and empty div and gave it an id of "message" so we can display a message showing what function is being called.
If you want to start your app and look at the localhost page, you will see two buttons like this:
If you click them, it seems nothing happens. In reality we have buttons which call the non-existant functions takeOff()
and land()
, so perhaps we should create those functions.
First we need to include our socket.io scripts on our html page. After the  tag and before the  tag we will add the scripts.
The first one adds socket.io.
The second script creates client side functions to trigger server side functions (in app.js).
Making progress!! Now we have two empty client side functions which are triggered when the corresponding button is pressed. If we consider what we want the functions to do, I can think of three things.
Most importantly, I want the function in the client side to tell the server side to do someting (like make the drone take off). We do this by telling the socket to "emit" a call to the server side.
socket.emit('takeOff');
I also want show a message on our page saying what the drone is (supposed to be) doing. We do this by getting the element we created with the id of "message" and setting the html to whatever we want.
document.getElementById('message').innerHTML = "taking off!";
The third thing, a personal preference, I like to console log something, so I can see in the console when the function has been called.
console.log("Flying");
After repeating the same process for the landing function, your index.html file should look something like this.
If we want to start up our app again and check functionality, your buttons would log the commands "taking off!" and "landing!" It also should show our message in the div when the button is pressed:
Our client side functions are working! They are emitting a call to the server side. Now let's build the functions in app.js which can tell the drone what we want it to do.
Lets start with our empty function to receive the call from the client side.
socket.on('takeOff', function () { }); socket.on('land', function () { });
This basically says, when you receive the "takeOff" call from the client side, do something. Remember way back when we first started we used client.takeOff();
to make the drone take off? Well, we are going to do it again, just within the functions this time. Same with client.land();
Simply paste those two lines into their corresponding functions.
I also like to add in a console.log("App Takeoff!")
and console.log("App land!")
so I know we are in the app functions. Below is a screen shot of my browser page and terminal at this point.
OK now that we have the understanding of how the socket works, add in the rest of the commands you might want (turn left, turn right, etc)
Embeded Video
Through all of this (building the express app) your server port 8000 should still be able to stream video while your port 3000 has the client side. It would be nice if we could see the video on the page with the buttons though, right?
Lets look at how to do that.
First let’s make another button in the index.html file
<button type="button" name="button" onclick="streamVideo()">Stream Video</button>
Also in index.html, let’s add a div where the video will go:

I also threw a couple line breaks in between, just so things are lined up a bit neater
Now the body of my html looks like this:
Now our button needs a function in the socket.io script to call. In the index.html file we will add a function.
function streamVideo(){ socket.emit('streamVideo'); document.getElementById('message').innerHTML = "Streaming Video!"; console.log("streaming"); document.getElementById('video').innerHTML = "<iframe width='640' height='360' src='http://<IP_ADDRESS>:8000/index.html'>"; };
The script portion of our index.html should look like this:
To round out the server side of this function, we will add a function in app.js.
socket.on('streamVideo', function () {
console.log('App video');
});
Which simply logs ‘App video’ in the terminal.
Let’s try it out.
- connect to the drone
- run app.js in terminal
- open localhost:8000 and localhost:3000
- in localhost:3000 click the stream video button
- your video should show up in a box just under your stream video button
And now you have a drone which you can control from an app you built, while watching the video stream! Check out the drone features and make new buttons! Do flips! Do fun stuff!
Also feel free to style your page as you would like. I used bootstrap and my buttons are now much better.


An Alien-Themed Brothel Just Bought a Sex Robot
by Dan RobitzskiSex Robot
Alien Cathouse, a UFO-themed brothel in Nevada, just bought a sex robot for clients who want to have a sci-fi inspired romp.
The brothel’s management wouldn’t disclose which type of robot they were purchasing to the tabloid Daily Star, but did say that it would have artificial intelligence capabilities and would allow the brothel to cater to customers with fetishes that don’t interest the human sex workers who work there. The high-tech upgrade is a bit of a bizarre novelty — what alien-themed sex robot wouldn’t be? — but it’s also sign that sex robots are slowly becoming mainstream.
The Future Is Coming
Sex workers at Alien Cathouse who spoke to Daily Star had mixed reactions to the news, which is coupled with the debut of “teledildonics” services for remote clientele.
“As an honest-to-goodness, flesh-and-blood, cougar-ific cuddle queen I am very excited about the addition of sex-bot playtime and remote interaction options at the brothel,” Cathouse employee Stella Renée told Daily Star. “Expanding our technological and social stiletto-print is imperative. Adapt or die!”
Just Another Thing
Other sex workers, like Cathouse employee Lisa Grace, were more ambivalent about the incoming technology and saw it as just another tool.
“I’m not really bothered by it. Sex toys have been around for centuries. Most customers come in for the human interaction.”


The vibrant city of Vienna is host to a great range of annual events and festivals, with everything from jazz festivals, to light shows, to film festivals. Whether you are in the city to sight-see over the weekend or on a trip for business, plan your stay right to make sure it coincides with one of these unique festivals in Berlin.
Vienna's lifeball is a surprising success story. It was started in 1993 in Vienna as an AIDS charity event and quickly became the biggest, most color- and successful event of its sort throughout Europe.The ball's aim is rather obvious: fund raising to support various AIDS related activities from preventation to counselling and direct aid to HIV positive people.
Open-air festival 'Donauinselfest' has taken place over 20 time and is already a favourite among locals and visitors. The festival is organised once a year and spreads all over the popular recreational mecca Danube Island. It attracts up to 3 million visitors with free entry and international stars. The island can easily accommodate this amount of visitors: More than 19 stages ('isles') offer entertainment from pop, rock, jazz to hip hop. Don't miss it!
Vienna's major film festival Viennale took place for the first time in 1960. Since then it has aimed to present international and Austrian films of high-quality and is proud of its international reputation.Venues are spread over Vienna's historic centre. Usually, about 200 films, documentaries and short films are broadcast and attract more than 70,000 visitors!
At midnight you will hear famous Pummerin (St. Stephen’s Cathedral) strike! Apart from that, everything can happen during the biggest celebration of the year. You can opt for an open-air party inclusive last minute waltz course all over Vienna’s first district (‘Silvesterpfad’), escape three-four time at various clubs.Just before midnight you can watch the official fireworks, which are supported by considerable private efforts, illuminate the city!
Visiting the Prater, a large natural park between the Danube and the Danube Canal, is a little like stepping into another world.A highlight for sightseers is taking a ride on the famous Giant Wheel,landmark that has provided views over the city.
Know MoreOne of the world's largest and most splendid theaters, the Vienna State Opera House (Wiener Staatsoper) has hosted many of the world's most prominent composers, conductors, soloists, and dancers.
Know MoreThe National Theater, has been famous for its productions of German-language plays. After devastation by bombing and fire in 1945, the theater eventually reopened in 1955 and has since grown in stature as the country's most important theater.
Know More


Please comes with built-in rules for Go, Python, Java, C++, Protocol Buffers and a few other bits & pieces. While it's nice to have a bunch of capabilities by default, it's obviously not practical for every language to be part of the core repo, and indeed part of the original design was to make it easy to add support for new languages without having to update the core code.
We collect support for additional languages in a separate repo. These are somewhat pithily named Pleasings and have rules for various new languages that are either still pretty early stage and unstable (the rules, not the language :) ) or sufficiently esoteric that having them part of the core seems inappropriate.
The simplest and most lightweight way to load new rules is to do it directly with
subinclude
, like so:
subinclude('@pleasings//rust')
rust_library(
name = 'my_rust_lib',
srcs = ['mine.rs'],
)
Some rules may have extra requirements, for example some single package in which you have to set up a one-off set of targets. The individual rules will document what's required.
As noted the above solution is nice and lightweight, and Please will take care of deduplicating & caching the download from github, so it works fairly well for straightforward cases. But there are times when you might want more control, like pinning to a particular version so you're not broken by any incompatible changes, or hash verifying the downloaded rules so you know you're always getting what you expect.
The idiomatic way of achieving this is to set up one centralised package to do the
download more carefully and subinclude from there. Conventionally we use
//build_defs
but of course this package can be anywhere. You'd set up
//build_defs/BUILD
as follows:
package(default_visibility = ['PUBLIC'])
remote_file(
name = 'rust',
url = 'https://raw.githubusercontent.com/thought-machine/pleasings/4a8158a65ef39e7dd9a1569fbfa1e5eec398e066/rust/rust.build_defs',
hashes = [
'bbfa10e522cfc870bfcbfbae6b899b770b54031a',
],
)
Then from any other package in your repo you could write the following:
subinclude('//build_defs:rust')
rust_library(
name = 'my_rust_lib',
srcs = ['mine.rs'],
)
This has the advantage of a shorter call to subinclude
in each package,
but more seriously states the expected revision & hash in a centralised location so
your build always uses the same upstream version of the rules to compile it.
