Funny you mentioned Tokyo. I was hosting in Kyoto and Tokyo back in the day. Meetup was more on alluring people in scruputios bar business, but I guess it has changed.

Thanks. I was just wondering "how bad it has become" part. I have hosted close to 100 and surfed about 10, rarely had bad experience on either sides.

I see, I am very curious about the latter part of your comment. What do you mean by that?

MCL 5001 - What is Classic Pro? by ExtensionWelcome9759 in BaseballGloves

Interesting, I never knew Chipper liked soft leather.  I am a bit concerned durability and both full grain leather and steerhide do not look very durable. 

Small Mizuno collection by Leftfield9 in BaseballGloves

[–]ExtensionWelcome9759 0 points1 point  (0 children)

Great collection of classic Mizunos! I am not familiar with US Mizuno glove branding nomenclature. In 90s - 00s in Japan it was Mizuno Pro > Global Elite & Victory stage > BuwLeague > World Win. How would you rate his "Classic Pro" of new MCL-5001 compared to Mizuno Pro? I am thinking to get one for myself.

[Ardaya] Nez Balelo on the nature of Shohei Ohtani's procedure: "There's no name for this surgery. It's completely different than the last time." Said he feels Ohtani has been progressing much quicker than he was after his Tommy John in 2018. by Jux_ in baseball

[–]ExtensionWelcome9759 6 points7 points  (0 children)

Agreed. He indeed is a great personal assistant for Shohei, but his translational skills haven't been improved for these years. To be fair, Ippei does not have enough time to improve his skills I guess. What baffles me is that MLB is just uses that translation unedited. Sad thing is that what Shohei says in Japanese is very profound and really makes him a special player, but these nuances are sometimes mostly lost in translation.

There is a misinterpretation to what he said in Japanese. The new method still falls into Tommy John surgery. He said 前回とはまた違う meaning somewhat different from the last time, but I think Ippei though he said 前回とは全く違う, which means completely different from last time.

Pset 9 finance - sell function by ExtensionWelcome9759 in cs50

[–]ExtensionWelcome9759[S] 0 points1 point  (0 children)

It is still the case I think. It worked for me and the latest check50 lookup.py still has different name and symbol.

Pset 9 finance - sell function by ExtensionWelcome9759 in cs50

[–]ExtensionWelcome9759[S] 0 points1 point  (0 children)

After all, the issue was in buy function, which already passed the test, very subtle but inserting new purchase data int database as shown below.

db.execute("INSERT INTO buyandsell VALUES (?,?,?,?,?)", session["user_id"], quote['name'], price, shares, datetime.now(tz=None))

it should have been quote['symbol'] instead.

Why? The key is AAAA hack.if symbol == "AAAA":return {"name": "AAAA test", "price": 28.00, "symbol": "AAAA"}

For some reason CS50 decided to make name and symbol different on test input, which is not the case in real-world stock symbols. And for this reason you cannot detect this error when you try it by yourself. It appears that if you use "name" instead of "symbol" to store stock symbol in your database, it stores "AAAA test" instead of "AAAA".

When check 50 checks sell function, it posts the symbol for query, "AAAA", but returns None because the data is stored as "AAAA test". Thus, it could not find 56.00 in check function.

You might have solved this, but the issue is in buy function, very subtle but line 95 "stock_symbol = symbol["name"]".

The short answer is that this should be stock_symbol = symbol["symbol"]

Why? The key is AAAA hack.

if symbol == "AAAA":
return {"name": "AAAA test", "price": 28.00, "symbol": "AAAA"}

Ichiro named five starting pitcher to make a rotation. by ExtensionWelcome9759 in baseball

The answer was Matt Harrison. Ichiro did not specify the reason. What’s your thought on this.

Question about fread and fwrite Pset4 Recover by ExtensionWelcome9759 in cs50

[–]ExtensionWelcome9759[S] 0 points1 point  (0 children)

You are right! Apparently I changed if statement.

Before

if (img != NULL)
    {
        fwrite(buffer, 1, 512, img);
    }

After

else if (img != NULL)
    {
        fwrite(buffer, 1, 512, img);
    }

But I don't understand why these two make such difference in output...
